Cause
There is a known issue in VSS functionality of MS SQL 2005, which is fixed in later a service pack. Or the VSS provider is broken and needs to be re-registered.
Solution
Make sure you have the latest MS SQL service packs installed for all instances on the machines.
Re-register the VSS provider using following batch file:
(!)Do not attempt this solution on Windows 2008 R2 or newer operating systems
(!) We recommend doing a partition backup before re-registering the VSS components.
After upgrading, the backups fails with "Failed to set the snapshot bitmap". To solve this issue, remove the Acronis VSS Provider from Windows registry

Hier können Sie zwei COM+ Fehler sehen. Einer der Fehler deutet auf den SnapVSSProvider und der zweite auf die snapapivss.dll. Das deutet auf ein Problem mit der Installation des Acronis VSS Providers hin.
Hier sind die beiden Fehler Codes, die im Log zu finden sind:
0x80110401 - Fehler beim Zugriff auf ein oder mehrere Objekte - die Fehler Information kann mehr Details enthalten.
0x8011041A - Die Komponenten Installation des DllRegisterServer schlägt fehl
Die häufigste Ursache für diesen Fehler ist, dass der Volume Shadow Copy Dienst deaktiviert oder nicht gestartet ist. Sie sollten sicherstellen, dass der Dienst nicht deaktiviert ist und den Dienst zum Test starten. Falls der Dienst aus irgend einem Grund scheitert, meint das es ein Problem mit dem VSS Subsystem selbst gibt.
Falls das Starten des Volume Shadow Copy Dienstes nicht hilft, fahren Sie bitte wie folgt fort:
Löschen Sie den Acronis VSS Provider aus der Systemsteuerung -> Verwaltung -> Komponentendienste -> Computers -> Mein Computer -> COM+ Anwendungen -> System Anwendungen
Löschen Sie die Datei \Windows\System32\snapapivss.dll, falls es existiert
Finden und löschen Sie alle Registry Schlüssel (Start -> Ausführen-> Regedit -> Enter), welche folgenden GUID's enthalten:

Backup on Windows XP fails with error "Failed to create volume snapshot" if MS SQL Server is installed.
This article applies to:
Acronis Backup & Recovery 11.5 (Build 11.5.37588 or higher)
Symptoms
You have installed Acronis Backup & Recovery 11.5 on a Windows XP System;
On this system MS SQL Server is installed and running;
(!) MS SQL Express 2008 is automatically installed along the installation of Acronis Management Server component.
You run a disk or volume backup with the default settings:
Use VSS option = enabled (default backup option value);
Software-System provider or Software-Select automatically selected (default backup option value);
Enable VSS Full Backup is disabled (default backup option value);
This backup fails with:
Failed to create volume snapshot.
Cause
This is an issue in the product
Solution
To work around this issue, please enable the VSS Full backup option.
Navigate to the backup plan options or to the default backup options -> Volume Shadow Copy Service and enable the VSS Full backup option. See Enabling VSS Full backup in user guide.
Case 1: Database or storage group recovery to MS Exchange fails in the end of operation:
You run database-level recovery task and it fails at the end of the task with VSS error similar to the following:
Message: A Volume Shadow Copy Service (VSS) API error has occurred. Failed to notify Microsoft Exchange Server VSS Writer that the current recovery has completed.
Also the following error may be shown in the Event Viewer:
Information Store (2356) Second Storage Group: Database C:\Program Files\Microsoft\Exchange Server\Mailbox\Second Storage Group\Public Folder Database.edb requires log files 2886-2887 in order to recover all committed data. Recovery could only locate up to log file C:\Program Files\Microsoft\Exchange Server\Mailbox\Second Storage Group\E01.log, and could not locate log generation 2887. If the log file cannot be found, the database(s) can be recovered manually, but this will result in losing committed data.
Case 2: Database or storage group recovery to MS Exchange fails at the beginning of operation.
You run database-level recovery task and it fails at the end of the task with VSS error similar to the following:
Message: A Volume Shadow Copy Service (VSS) API error has occurred. Failed to notify Microsoft Exchange Server VSS Writer to prepare for recovery.
Case 3: Recovered MS Exchange database or storage group cannot be mounted
You have recovered database or storage group to a separate folder and try to mount it - operation fails because of database dirty shutdown state.
After that you launch "eseutil /r <Enn>" to bring the database to Clean Shutdown state, but it fails with the error message:
Operation terminated with error -582 (JET_errCommittedLogFilesMissing, One or more logs that were committed to this database, are missing. These log files are required to maintain durable ACID semantics, but not required to maintain consistency if the JET_bitReplayIgnoreLostLogs bit is specified during recovery.) after 0.250 seconds.
Cause
Some transaction logs are missing (or corrupted) in the backup.
It is possible to recover such database with some additional steps, but data committed from missing transaction log will be lost.
Solution
Database in the target location may be in inconsistent state after failed recovery with VSS error.
In order to recover database from the backup to the target location successfully, it is necessary restore database files to temporary location and repair the database manually.
After that you can move extracted database files to the target location.
Please follow the steps below:
Recover database or storage group to some temporary folder;
Open a command line; Go to Start -> run -> cmd (when UAC activated, right click and start as administrator);
Navigate to temporary folder where database or storage group was extracted (using CD command), for example:
CD c:\<PATH_TO_FOLDER>\
Repair extracted database using command:
eseutil /r Enn /a /i /D <DB Catalog> (!) Enn is transaction log files prefix - for example, E00. (!)<DB Catalog> - folder with extracted .edb file
Make sure that database is healthy (for healthy database "State" field value is "Clean Shutdown"):
eseutil /m <EDB-file> (!) .EDB file name in the target folder where target database\storage group (which should be restored with data from the backup) is located.
Delete contents of target folder (after failed recovery database may be inconsistent);
Move contents of the temporary folder to target folder location;
Make sure that .EDB file name is the same as you noted on step 5. Rename it if necessary;
Mount Exchange database in target location folder.
Nach einem Upgrade schlägt ein Backup fehl mit "Snapshot Bitmap konnte nicht gesetzt werden". Um dieses Problem zu lösen, entfernen Sie den Acronis VSS Provider aus der Windows Registry.

Ursache
Während der Aktualisierung hat der Acronis Installer nicht den alten VSS Provider aus der Registry gelöscht. Wegen dieses Schlüssels scheitert die VSS Operation.
Lösung
Um das Problem zu lösen, folgen Sie diesen Schritten:
Öffnen Sie den Windows Registry Editor. Gehen Sie auf Start -> Ausführen-> regedit.exe -> drücken Sie Enter;
Als Workaround verwenden Sie den Microsoft VSS statt den Acronis VSS Provider

Acronis Backup & Recovery 11.5
Symptome
1. Sie haben einen Windows Server mit einer Active Directory Rolle (ein SBS oder Domain Controller) und der NTDS VSS Writer ist im System vorhanden. (!) Sie können die Liste der Writer im System prüfen, indem Sie das Kommando "vssadmin list writers" via Start -> Ausführen -> cmd ausführen.
The Acronis Managed Machine service user does not have appropriate rights for running this operation with VSS Service for SQL Server. As a result the snapshot of the SqlServerWriter fails.
You can check if the SqlServerWriter fails with the command vssadmin list writers.
Open command prompt (Win+R -> cmd -> Enter):
Enter this command: vssadmin list writers:
The output should contain this: .... Writer name: 'SqlServerWriter' Writer Id: {a65faa63-5ea8-4ebc-9dbd-a0c4db26912a} Writer Instance Id: {ac3d731f-6a0f-4537-8d6f-1ffad6dd9d8f} State: [8] Failed Last error: Non-retryable error ....
Solution
Please check what user is used for running the Acronis Managed Machine service:
Open command prompt (Win+R -> cmd -> Enter);
Enter this command: services.msc:
Navigate in the overview to Acronis Managed Machine service: In this example the Acronis Agent User 5 is set to start this service.
It is preferred that the user of the Acronis Managed Machine service is member of the domain admin group. If you need to add the appropriate rights manually, please see Acronis Backup & Recovery: Adding Necessary Rights.

This article describes how to resolve and troubleshoot the error "Error creating snapshot" encountered while backing up a physical or virtual machine. Generally following snapshot errors may occur:
Failed to create volume snapshot Failed to create VSS snapshot Failed to start creating the volume snapshot Awaiting task 'CreateSnapshot' has failed. Reason: Response timed out There Is Not Enough Free Space on the Drive Where the Snapshot Cache File Is Located. Failed to Set Snapshot Bitmap. Not Locked Creating a quiesced snapshot failed Failed to Read the Snapshot
Solution
Follow these steps to troubleshoot snapshot issues:
Get familiar with technology of snapshot creation in the Aboutpart.
Follow to Troubleshootingpart to troubleshoot and resolve the issue.
The SnapAPI module is in charge of all I/O operations on the hard disk of Acronis software working in Windows. It also allows creating backups under running Windows with an unlimited number of files open for reading and writing without the necessity to reboot the computer.
The Snapshot Manager driver (snapman.sys) is installed as an upper filter between the file system drivers and the volume drivers, so SnapAPI can intercept all the read and write requests passing to a partition. The SnapAPI drivers binary files and registry keys/settings are listed below:
Windows 2000, Windows 2000 Server, Windows XP, Windows 2003, Windows Server 2003, Windows Vista, Windows Server 2008, Windows Server 2012,Windows 7, Windows 8, Windows 8.1
Message: Awaiting task 'CreateSnapshot' has failed. Reason: Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.
Awaiting task has failed (Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine)
Creating a quiesced snapshot failed

An error occurred while quiescing the virtual machine. See the virtual machine's event log for details.
VMware failed to create a quiesced snapshot of the selected virtual machine. To back up the machine, power off the machine before the process or uninstall the Volume Shadow Copy Services Support feature of VMware Tools from the VM.
Awaiting task 'CreateSnapshot' has failed. Reason: Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.
Awaiting task 'CreateSnapshot' has failed. Reason: File <unspecified filename> is larger than the maximum size supported by datastore '<unspecified datastore>
Windows To use a snapshot, the backup plan has to run under the account with the Administrator or Backup Operator privileges. If a snapshot cannot be taken, the backup will fail. A user who is a member of the Backup Operators group, also has the management right to back up and recover the entire machine or any data on the machine, with or without using a disk snapshot. Using a hardware snapshot provider may still require administrative privileges. The user for Acronis Managed Machine Service must belong to the Backup operators group. On Domain Controllers, the user must also be a member of the Domain Administrators group to have access to the Active Directory during a backup with VSS. So, please ensure the user specified for backup plan and Managed Machine Service is in Backup operators group. See: 15276: Acronis Backup & Recovery: Adding Necessary Rights and 19140: Acronis Backup & Recovery 10: Changing Users for Acronis Services.
Linux When managing a machine running Linux, the user has or obtains the root privileges, and so can:
Back up and recover any data or the entire machine, having full control over all Acronis Backup & Recovery 11.5 agent operations and log files on the machine.
Manage local backup plans and tasks owned by any user registered in the operating system.
To avoid routine logging on to the system as root, the root user can log on with the ordinary user credentials and then switch user as required.
Acronis Backup & Recovery 11.5 can back up and recover the following file systems with the following limitations:
FAT16/32
NTFS
ReFS - volume recovery without the volume resize capability. Supported in Windows Server 2012/2012 R2 only.
Ext2/Ext3/Ext4
ReiserFS3 - particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
ReiserFS4 - volume recovery without the volume resize capability; particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
XFS - volume recovery without the volume resize capability; particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
JFS - particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
Linux SWAP
To create an exact copy of a disk or volume on a physical level, select the back up sector-by-sector check box. The resulting backup will be equal in size to the disk being backed up (if the Compression level option is set to 'None'). Use the sector-by-sector backup for backing up drives with unrecognized or unsupported file systems and other proprietary data formats.
Acronis Backup & Recovery 11.5 can back up and recover corrupted or non-supported file systems using the sector-by-sector approach only.
This option is effective only for Windows operating systems. This option applies to disk-level backup. This option also applies to file-level backup when the file-level backup is performed by taking a snapshot. (The File-level backup snapshot option determines whether a snapshot will be taken during file-level backup). The option determines whether to take snapshots of multiple volumes at the same time or one by one.
The preset is: Enable.
When this option is set to Enable, snapshots of all volumes being backed up will be created simultaneously. Use this option to create a time-consistent backup of data spanned across multiple volumes, for instance for an Oracle database.
When this option is set to Disable, the volumes' snapshots will be taken one after the other. As a result, if the data spans across several volumes, the resulting backup may be not consistent.
This option is effective only for file-level backup in Windows and Linux operating systems. This option defines whether to back up files one by one or by taking an instant data snapshot.
Note: Files that are stored on network shares are always backed up one by one.
The preset is: Create snapshot if it is possible. Select one of the following:
Always create a snapshot The snapshot enables backing up of all files including files opened for exclusive access. The files will be backed up at the same point in time. Choose this setting only if these factors are critical, that is, backing up files without a snapshot does not make sense. To use a snapshot, the backup plan has to run under the account with the Administrator or Backup Operator privileges. If a snapshot cannot be taken, the backup will fail.
Create a snapshot if it is possible Back up files directly if taking a snapshot is not possible.
Do not create a snapshot Always back up files directly. Administrator or Backup Operator privileges are not required. Trying to back up files that are opened for exclusive access will result in a read error. Files in the backup may be not time-consistent.
These options are effective only for Windows operating systems and Acronis Backup & Recovery products. The option defines whether a Volume Shadow Copy Service (VSS) provider has to notify VSS-aware applications that the backup is about to start. This ensures the consistent state of all data used by the applications; in particular, completion of all database transactions at the moment of taking the data snapshot by Acronis Backup & Recovery 11.5. Data consistency, in turn, ensures that the application will be recovered in the correct state and become operational immediately after recovery.
The preset is: Use Volume Shadow Copy Service
If you select Do not use VSS, the data snapshot will be taken by Acronis Backup & Recovery 11.5.
Choose Do not use VSS if your database is incompatible with VSS. Backup process is fastest, but data consistency of the applications whose transactions are not completed at the time of taking a snapshot cannot be guaranteed. You may use Pre/Post data capture commandsto indicate which commands should be performed before and after taking the snapshot. This ensures that the data is being backed up in a consistent state. For instance, specify pre-data capture commands that will suspend the database and flush all caches to ensure that all transactions are completed; and specify post-data capture commands that will resume the database operations after the snapshot is taken.
If enabled, logs of Microsoft Exchange Server and of other VSS-aware applications (except for Microsoft SQL Server) will be truncated after each successful full, incremental or differential backup.
Leave this option disabled in the following cases:
If you use Acronis Backup & Recovery 11.5 Agent for Microsoft Exchange Server or third-party software for backing up the Exchange Server data. This is because the log truncation will interfere with the consecutive transaction log backups.
If you use third-party software for backing up the SQL Server data. The reason for this is that the third-party software will take the resulting disk-level backup for its "own" full backup. As a result, the next differential backup of the SQL Server data will fail. The backups will continue failing until the third-party software creates the next "own" full backup.
If other VSS-aware applications are running on the machine and you need to keep their logs for any reason.
Enabling this option does not result in the truncation of Microsoft SQL Server logs. To truncate the SQL Server log after a single-pass backup, enable the Log truncation setting in the Single-pass disk and application backup section of the Create backup planor Back up now page.
Enable this option when using VSS on a machine that has Windows XP and runs Microsoft SQL Server. If you leave the option disabled, the backup may fail.
Ensure that Windows\system32\drivers\snapman.sys is installed and of the correct version.
Check that snapman driver is installed an working: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\snapman
In windows registry there must be single versions if snapman driver, check keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318} -> snapman* string in the UpperFilters value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F} -> snapman* string in the LowerFilters value
It is always better to use the most actual SnapAPI drivers. Request the latest stable version and install it. Generally released version is available under: 5831: SnapAPI Versions for Acronis Products.
For Linux operating systems check 41283: Updating SnapAPI Module in Linux. The setup program tries to automatically compile the SnapAPI module for your Linux kernel. If it fails to do so, please refer to the file /usr/lib/Acronis/BackupAndRecovery/HOWTO.INSTALL.
Due to the limits of VSS architecture at one time only one application in the system can create a snapshot. In other words, a critical part of creating a VSS snapshot is serialized. When a collision occurs application receives the error VSS_E_SNAPSHOT_SET_IN_PROGRESS (0x80042316). Acronis VssRequestor then performs several attempts to create a snapshot. By default it makes 10 attempts for 5 minutes.
Beginning with the SnapAPI build #2228 these values can be set in the registry:
Collect following information and contact Acronis Customer Central. Note that all logs should be collected on the machine which is performing backup. In case a virtual machine is being backed up over host logs from the host as well as from the guest system should be collected.
create key HKLM\SOFTWARE\Acronis\SnapAPI::DWORD::"VssComApiTracing"==1 to trace (disable with ==0)
log files will be saved in 2000/XP/2003: Documents and Settings\All Users\Application Data\Acronis\VssComLogs\ Vista/Win7/2008: Users\All Users\Acronis\VssComLogs\
vss_requestor.exe tracing (SnapAPI installer build #2170 and higher)
create key HKLM\SOFTWARE\Acronis\SnapAPI::DWORD::"VssRequestorTracing"==1 to trace (disable with ==0)
log files will be saved in 2000/XP/2003: Documents and Settings\All Users\Application Data\Acronis\VssRequestorLogs\ Vista/Win7/2008: Users\All Users\Acronis\VssRequestorLogs\
Note: always collect system information after the issue has been reproduced. If Debug tracing, SnapAPI logs and VssRequestor logs are enabled, System Report (or AcronisInfo) will include all these logs.
The better way to provide backup plan settings is to export the backup plan as .xml file. See Export and import of backup plans. For Acronis True Image create screenshots of the backup plan settings: Creating Screenshots. Also provide exact details of what is being backed up.

Hier können Sie zwei COM+ Fehler sehen. Einer der Fehler deutet auf den SnapVSSProvider und der zweite auf die snapapivss.dll. Das deutet auf ein Problem mit der Installation des Acronis VSS Providers hin.
Hier sind die beiden Fehler Codes, die im Log zu finden sind:
0x80110401 - Fehler beim Zugriff auf ein oder mehrere Objekte - die Fehler Information kann mehr Details enthalten.
0x8011041A - Die Komponenten Installation des DllRegisterServer schlägt fehl
Die häufigste Ursache für diesen Fehler ist, dass der Volume Shadow Copy Dienst deaktiviert oder nicht gestartet ist. Sie sollten sicherstellen, dass der Dienst nicht deaktiviert ist und den Dienst zum Test starten. Falls der Dienst aus irgend einem Grund scheitert, meint das es ein Problem mit dem VSS Subsystem selbst gibt.
Falls das Starten des Volume Shadow Copy Dienstes nicht hilft, fahren Sie bitte wie folgt fort:
Löschen Sie den Acronis VSS Provider aus der Systemsteuerung -> Verwaltung -> Komponentendienste -> Computers -> Mein Computer -> COM+ Anwendungen -> System Anwendungen
Löschen Sie die Datei \Windows\System32\snapapivss.dll, falls es existiert
Finden und löschen Sie alle Registry Schlüssel (Start -> Ausführen-> Regedit -> Enter), welche folgenden GUID's enthalten:

Cause
By default the product uses COPY method of VSS snapshotting. However, Microsoft 'SqlServerWriter' VSS Writer doesn't support VSS COPY method on Windows XP - and thus VSS snapshot can't be created successfully in this OS. The workaround is to switch to VSS Full backup option (see below) which will switch the VSS snapshot method to FULL - and it is supported properly by SqlServerWriter in Windows XP.
Solution
To work around this issue, please enable the VSS Full backup option.
Navigate to the backup plan options or to the default backup options -> Volume Shadow Copy Service and enable the VSS Full backup option. See Enabling VSS Full backup in user guide.
More information
(!) Ifthe issue happens NOT on Windows XP, or the above workaround implemented on Windows XP machine doesn't help - then there must be some other Microsoft VSS corruption (e.g. another component of Microsoft VSS subsystem malfunctions). You'll need to investigate this VSS issue separately, e.g. as described in Acronis Backup & Recovery: VSS Troubleshooting Guide
Case 1: Database or storage group recovery to MS Exchange fails in the end of operation:
You run database-level recovery task and it fails at the end of the task with VSS error similar to the following:
Message: A Volume Shadow Copy Service (VSS) API error has occurred. Failed to notify Microsoft Exchange Server VSS Writer that the current recovery has completed.
Command 'Recovering Microsoft Exchange databases' has failed.

Also the following error may be shown in the Event Viewer:
Information Store (2356) Second Storage Group: Database C:\Program Files\Microsoft\Exchange Server\Mailbox\Second Storage Group\Public Folder Database.edb requires log files 2886-2887 in order to recover all committed data. Recovery could only locate up to log file C:\Program Files\Microsoft\Exchange Server\Mailbox\Second Storage Group\E01.log, and could not locate log generation 2887. If the log file cannot be found, the database(s) can be recovered manually, but this will result in losing committed data.
Case 2: Database or storage group recovery to MS Exchange fails at the beginning of operation.
You run database-level recovery task and it fails at the end of the task with VSS error similar to the following:
Message: A Volume Shadow Copy Service (VSS) API error has occurred. Failed to notify Microsoft Exchange Server VSS Writer to prepare for recovery.
Failed to recover storage group or database 'Mailbox Database 0328867699'.

Case 3: Recovered MS Exchange database or storage group cannot be mounted
You have recovered database or storage group to a separate folder and try to mount it - operation fails because of database dirty shutdown state.
After that you launch "eseutil /r <Enn>" to bring the database to Clean Shutdown state, but it fails with the error message:
Operation terminated with error -582 (JET_errCommittedLogFilesMissing, One or more logs that were committed to this database, are missing. These log files are required to maintain durable ACID semantics, but not required to maintain consistency if the JET_bitReplayIgnoreLostLogs bit is specified during recovery.) after 0.250 seconds.
Cause
Some transaction logs are missing (or corrupted) in the backup.
It is possible to recover such database with some additional steps, but data committed from missing transaction log will be lost.
Solution
Database in the target location may be in inconsistent state after failed recovery with VSS error.
In order to recover database from the backup to the target location successfully, it is necessary restore database files to temporary location and repair the database manually.
After that you can move extracted database files to the target location.
Please follow the steps below:
Recover database or storage group to some temporary folder;
Open a command line; Go to Start -> run -> cmd (when UAC activated, right click and start as administrator);
Navigate to temporary folder where database or storage group was extracted (using CD command), for example:
CD c:\<PATH_TO_FOLDER>\
Repair extracted database using command:
eseutil /r Enn /a /i /D <DB Catalog> (!) Enn is transaction log files prefix - for example, E00. (!)<DB Catalog> - folder with extracted .edb file
Make sure that database is healthy (for healthy database "State" field value is "Clean Shutdown"):
eseutil /m <EDB-file> (!) .EDB file name in the target folder where target database\storage group (which should be restored with data from the backup) is located.
Delete contents of target folder (after failed recovery database may be inconsistent);
Move contents of the temporary folder to target folder location;
Make sure that .EDB file name is the same as you noted on step 5. Rename it if necessary;
Mount Exchange database in target location folder.

Ursache
VSS Provider mit CLSID angegeben in der Ereignisanzeige-Fehlermeldung schlägt bei der Initializierung des Snapshots fehl und verursacht Fehlschlagen von Snapshot.
Lösung
Um das Problem zu lösen, reparieren Sie den fehlerhaften VSS-Provider:
Prüfen Sie, ob der fehlerhafte Provider registriert ist: vssadmin list providers
Prüfen Sie, ob der entsprechende Dienst existiert und aktiviert ist:
Finden Sie den entsprechenden Dienst unter den Diensten. Stellen Sie den Starttyp auf manuell.
Navigieren Sie zu der Registry und finden Sie den Dienst. Stellen Sie sicher, der Schlüssel ist nicht leer: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services[VSS Provider Name]
Wenn eine der Voraussetzungen nicht getroffen ist, führen Sie die Reparaturinstallation von der Provider durch. Starten Sie die Installationdatei von der entsprechenden Software und führen Sie die Reparaturinstallation durch. Für Acronis VSS Provider starten Sie die Installationsdatei von Acronis Backup & Recovery, wählen Sie "Acronis Backup & Recovery installieren", weiter wählen Sie "Reparieren". Kontaktieren Sie den Softwarehersteller von einer Drittparteisoftware.
Soll die Reparaturinstallation das Problem nicht beheben bzw. nicht möglich sein, entfernen Sie den fehlerhaften VSS Provider:
Öffnen Sie die Registry Start -> Ausführen -> regedit.exe -> Enter;
Navigieren Sie zu diesem Schlüssel: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\Providers\

Protokollname: Application Quelle: VSS Datum: Ereignis-ID: 8193 Aufgabenkategorie:Keine Ebene: Fehler Schlüsselwörter:Klassisch Benutzer: Nicht zutreffend Computer: Beschreibung: Volumeschattenkopie-Dienstfehler: Beim Aufrufen von Routine "Cannot find anymore diff area candidates for volume \\?\Volumexxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx\ [0]" ist ein Fehler aufgetretten. hr = 0x8000ffff
Ursache
Nicht genügend Speicher, um Volumenschattenkopie zu erstellen oder Schattenkopie ist für die Volume nicht aktiviert.
Lösung
Um prüfen zu können, ob die Volume genügend Speicher für eine Schattenkopie hat, erstellen Sie eine Schattenkopie mit Windows nativen Mitteln und stellen Sie sicher, dass die Schattenkopie erfolgreich erstellt werden kann. Falls notwendig, verschieben Sie Schattenspeicher zu einer anderen Volume oder machen Sie Platz frei.
Wählen Sie, auf welchem Betriebssystem das Backup ausgeführt wird:: Server OS or Workstation OS.
Navigieren Sie zu Mein Computer -> Klicken Sie mit der rechten Maustaste auf eine interne Volume -> Schattenkopien konfigurieren
Wählen Sie die Volume, die Sie prüfen müchten und klicken Sie auf Schattenkopie erstellen um zu prüfen, ob Speicherplatz für Schattenkopie ausreicht. Falls notwendig, passen Sie Speicherplatz an.
Sie können auch vssadmin utility benutzen, um Schattenkopie zu prüfen, Speicherplatz zu vergrößern oder zu verschieben.
Navigieren Sie zu Start -> Ausführen -> diskmgmt.msc. Überprüfen Sie die Größe von allen Volumen. Falls eine Volume 1024 MB oder kleiner ist, kann es nicht mit VSS gesichert werden, Erklärung dafür finden Sie in diesem Artikel von MSDN. Vergrößern Sie die Volume bis zu 1025 MB oder mehr, oder schließen Sie die Volume aus dem Backup aus.
Navigieren Sie zur Systemsteuerung -> System - >Computerschutz
Wählen Sie die Volume, die Sie prüfen möchten und klicken Sie auf Schattenkopie erstellen um sicherzustellen, dass Speicherplatz für eine Schattenkopie ausreicht. Falls notwendig, stellen Sie die Computerschutz ein und vergrößern Sie Schattenkopiespeicher.
Um prüfen zu können, ob eine Volume genügend Speicherplatz frei hat und eine Schattenkopie zu erstellen, führen Sie die ntbackup Utility aus und sichern Sie einige Daten von der Volume, die Sie prüfen möchten. Starten Sie cmd und geben Sie ntbackup.exe ein.
Falls notwendig, können Sie Speicherplatz für eine Schattenkopie vergrößern, indem Sie zu Systemsteuerung -> System -> Systemwiederherstellung navigieren und Speicherplatz konfigurieren.
Als Workaround verwenden Sie den Microsoft VSS statt den Acronis VSS Provider

Die Ursache der Probleme liegt in der Kommunikation zwischen dem Acronis VSS Provider und dem NTDS Writer, verursacht durch Acronis VSS Provider Limitationen. Wenn der Acronis VSS Provider für die VSS Unterstützung verwendet wird, erfolgt der finale Snapshot durch die Acronis SnapAPI Treiber Technologie. Der NTDS Writer benötigt den Snapshot Pfad, der durch die Besonderheiten der SnapAPI Snapshot Spezifikationen und den Acronis VSS Provider Funktionen nicht geliefert werden kann.
Lösung
Als Workaround verwenden Sie den Microsoft VSS Provider statt dem Acronis VSS Provider. Sie müssen die Änderung in der Option Volume Shadow Copy Service umstellen. Stellen Sie sicher, dass die Option VSS verwenden ausgewählt ist. Als Snapshot Provider stellen Sie folgendes ein: Software - System Provider.
(!) Es kann ein separates Problem mit Backups unter Verwendung des Microsoft VSS Providers auf Windows Small Business Server 2011 Systemen geben, nachdem das Microsoft SharePoint Foundation 2010 Service Pack 1 (SP1) installiert wurde.
There may be a separate issue where backups with Microsoft VSS provider on may not work correctly after installation.
Um das Dienstprogramm zu starten:
Öffnen Sie ein Administratives Kommando Prompt;
Wechseln Sie das Verzeichnis auf C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN
(!) Dieses Problem tritt nur auf Systemen mit einem Active Directory Dienst und NTDS VSS Writer auf. Falls Sie diesen Fehler auf einem anderen Betriebssytem haben, wird das Problem nicht von diesem Artikel behandelt. Bitte kontaktieren Sie Acronis Customer Central mit einer Referenz zu diesem Artikel.
The Acronis Managed Machine service user does not have appropriate rights for running this operation with VSS Service for SQL Server. As a result the snapshot of the SqlServerWriter fails.
You can check if the SqlServerWriter fails with the command vssadmin list writers.
Open command prompt (Win+R -> cmd -> Enter):
Enter this command: vssadmin list writers:
The output should contain this: .... Writer name: 'SqlServerWriter' Writer Id: {a65faa63-5ea8-4ebc-9dbd-a0c4db26912a} Writer Instance Id: {ac3d731f-6a0f-4537-8d6f-1ffad6dd9d8f} State: [8] Failed Last error: Non-retryable error ....
Solution
Please check what user is used for running the Acronis Managed Machine service:
Open command prompt (Win+R -> cmd -> Enter);
Enter this command: services.msc:
Navigate in the overview to Acronis Managed Machine service: In this example the Acronis Agent User 5 is set to start this service.
It is preferred that the user of the Acronis Managed Machine service is member of the domain admin group. If you need to add the appropriate rights manually, please see Acronis Backup & Recovery: Adding Necessary Rights.

This article describes how to resolve and troubleshoot the error "Error creating snapshot" encountered while backing up a physical or virtual machine. Generally following snapshot errors may occur:
Failed to create volume snapshot Failed to create VSS snapshot Failed to start creating the volume snapshot Awaiting task 'CreateSnapshot' has failed. Reason: Response timed out There Is Not Enough Free Space on the Drive Where the Snapshot Cache File Is Located. Failed to Set Snapshot Bitmap. Not Locked Creating a quiesced snapshot failed Failed to Read the Snapshot
Solution
Follow these steps to troubleshoot snapshot issues:
Get familiar with technology of snapshot creation in the Aboutpart.
Follow to Troubleshootingpart to troubleshoot and resolve the issue.
The SnapAPI module is in charge of all I/O operations on the hard disk of Acronis software working in Windows. It also allows creating backups under running Windows with an unlimited number of files open for reading and writing without the necessity to reboot the computer.
The Snapshot Manager driver (snapman.sys) is installed as an upper filter between the file system drivers and the volume drivers, so SnapAPI can intercept all the read and write requests passing to a partition. The SnapAPI drivers binary files and registry keys/settings are listed below:
Windows 2000, Windows 2000 Server, Windows XP, Windows 2003, Windows Server 2003, Windows Vista, Windows Server 2008, Windows Server 2012,Windows 7, Windows 8, Windows 8.1
Message: Awaiting task 'CreateSnapshot' has failed. Reason: Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.
Awaiting task has failed (Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine)

An error occurred while quiescing the virtual machine. See the virtual machine's event log for details.
VMware failed to create a quiesced snapshot of the selected virtual machine. To back up the machine, power off the machine before the process or uninstall the Volume Shadow Copy Services Support feature of VMware Tools from the VM.
Awaiting task 'CreateSnapshot' has failed. Reason: Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.
Awaiting task 'CreateSnapshot' has failed. Reason: File <unspecified filename> is larger than the maximum size supported by datastore '<unspecified datastore>
Windows To use a snapshot, the backup plan has to run under the account with the Administrator or Backup Operator privileges. If a snapshot cannot be taken, the backup will fail. A user who is a member of the Backup Operators group, also has the management right to back up and recover the entire machine or any data on the machine, with or without using a disk snapshot. Using a hardware snapshot provider may still require administrative privileges. The user for Acronis Managed Machine Service must belong to the Backup operators group. On Domain Controllers, the user must also be a member of the Domain Administrators group to have access to the Active Directory during a backup with VSS. So, please ensure the user specified for backup plan and Managed Machine Service is in Backup operators group. See: 15276: Acronis Backup & Recovery: Adding Necessary Rights and 19140: Acronis Backup & Recovery 10: Changing Users for Acronis Services.
Linux When managing a machine running Linux, the user has or obtains the root privileges, and so can:
Back up and recover any data or the entire machine, having full control over all Acronis Backup & Recovery 11.5 agent operations and log files on the machine.
Manage local backup plans and tasks owned by any user registered in the operating system.
To avoid routine logging on to the system as root, the root user can log on with the ordinary user credentials and then switch user as required.
Acronis Backup & Recovery 11.5 can back up and recover the following file systems with the following limitations:
FAT16/32
NTFS
ReFS - volume recovery without the volume resize capability. Supported in Windows Server 2012/2012 R2 only.
Ext2/Ext3/Ext4
ReiserFS3 - particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
ReiserFS4 - volume recovery without the volume resize capability; particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
XFS - volume recovery without the volume resize capability; particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
JFS - particular files cannot be recovered from disk backups located on Acronis Backup & Recovery 11.5 Storage Node
Linux SWAP
To create an exact copy of a disk or volume on a physical level, select the back up sector-by-sector check box. The resulting backup will be equal in size to the disk being backed up (if the Compression level option is set to 'None'). Use the sector-by-sector backup for backing up drives with unrecognized or unsupported file systems and other proprietary data formats.
Acronis Backup & Recovery 11.5 can back up and recover corrupted or non-supported file systems using the sector-by-sector approach only.
This option is effective only for Windows operating systems. This option applies to disk-level backup. This option also applies to file-level backup when the file-level backup is performed by taking a snapshot. (The File-level backup snapshot option determines whether a snapshot will be taken during file-level backup). The option determines whether to take snapshots of multiple volumes at the same time or one by one.
The preset is: Enable.
When this option is set to Enable, snapshots of all volumes being backed up will be created simultaneously. Use this option to create a time-consistent backup of data spanned across multiple volumes, for instance for an Oracle database.
When this option is set to Disable, the volumes' snapshots will be taken one after the other. As a result, if the data spans across several volumes, the resulting backup may be not consistent.
This option is effective only for file-level backup in Windows and Linux operating systems. This option defines whether to back up files one by one or by taking an instant data snapshot.
Note: Files that are stored on network shares are always backed up one by one.
The preset is: Create snapshot if it is possible. Select one of the following:
Always create a snapshot The snapshot enables backing up of all files including files opened for exclusive access. The files will be backed up at the same point in time. Choose this setting only if these factors are critical, that is, backing up files without a snapshot does not make sense. To use a snapshot, the backup plan has to run under the account with the Administrator or Backup Operator privileges. If a snapshot cannot be taken, the backup will fail.
Create a snapshot if it is possible Back up files directly if taking a snapshot is not possible.
Do not create a snapshot Always back up files directly. Administrator or Backup Operator privileges are not required. Trying to back up files that are opened for exclusive access will result in a read error. Files in the backup may be not time-consistent.
These options are effective only for Windows operating systems and Acronis Backup & Recovery products. The option defines whether a Volume Shadow Copy Service (VSS) provider has to notify VSS-aware applications that the backup is about to start. This ensures the consistent state of all data used by the applications; in particular, completion of all database transactions at the moment of taking the data snapshot by Acronis Backup & Recovery 11.5. Data consistency, in turn, ensures that the application will be recovered in the correct state and become operational immediately after recovery.
The preset is: Use Volume Shadow Copy Service
If you select Do not use VSS, the data snapshot will be taken by Acronis Backup & Recovery 11.5.
Choose Do not use VSS if your database is incompatible with VSS. Backup process is fastest, but data consistency of the applications whose transactions are not completed at the time of taking a snapshot cannot be guaranteed. You may use Pre/Post data capture commands to indicate which commands should be performed before and after taking the snapshot. This ensures that the data is being backed up in a consistent state. For instance, specify pre-data capture commands that will suspend the database and flush all caches to ensure that all transactions are completed; and specify post-data capture commands that will resume the database operations after the snapshot is taken.
If enabled, logs of Microsoft Exchange Server and of other VSS-aware applications (except for Microsoft SQL Server) will be truncated after each successful full, incremental or differential backup.
Leave this option disabled in the following cases:
If you use Acronis Backup & Recovery 11.5 Agent for Microsoft Exchange Server or third-party software for backing up the Exchange Server data. This is because the log truncation will interfere with the consecutive transaction log backups.
If you use third-party software for backing up the SQL Server data. The reason for this is that the third-party software will take the resulting disk-level backup for its "own" full backup. As a result, the next differential backup of the SQL Server data will fail. The backups will continue failing until the third-party software creates the next "own" full backup.
If other VSS-aware applications are running on the machine and you need to keep their logs for any reason.
Enabling this option does not result in the truncation of Microsoft SQL Server logs. To truncate the SQL Server log after a single-pass backup, enable the Log truncation setting in the Single-pass disk and application backup section of the Create backup planor Back up now page.
Enable this option when using VSS on a machine that has Windows XP and runs Microsoft SQL Server. If you leave the option disabled, the backup may fail.
Ensure that Windows\system32\drivers\snapman.sys is installed and of the correct version.
Check that snapman driver is installed an working: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\snapman
In windows registry there must be single versions if snapman driver, check keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318} -> snapman* string in the UpperFilters value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F} -> snapman* string in the LowerFilters value
It is always better to use the most actual SnapAPI drivers. Request the latest stable version and install it. Generally released version is available under: 5831: SnapAPI Versions for Acronis Products.
For Linux operating systems check 41283: Updating SnapAPI Module in Linux. The setup program tries to automatically compile the SnapAPI module for your Linux kernel. If it fails to do so, please refer to the file /usr/lib/Acronis/BackupAndRecovery/HOWTO.INSTALL.
Due to the limits of VSS architecture at one time only one application in the system can create a snapshot. In other words, a critical part of creating a VSS snapshot is serialized. When a collision occurs application receives the error VSS_E_SNAPSHOT_SET_IN_PROGRESS (0x80042316). Acronis VssRequestor then performs several attempts to create a snapshot. By default it makes 10 attempts for 5 minutes.
Beginning with the SnapAPI build #2228 these values can be set in the registry:
Collect following information and contact Acronis Customer Central. Note that all logs should be collected on the machine which is performing backup. In case a virtual machine is being backed up over host logs from the host as well as from the guest system should be collected.
create key HKLM\SOFTWARE\Acronis\SnapAPI::DWORD::"VssComApiTracing"==1 to trace (disable with ==0)
log files will be saved in 2000/XP/2003: Documents and Settings\All Users\Application Data\Acronis\VssComLogs\ Vista/Win7/2008: Users\All Users\Acronis\VssComLogs\
vss_requestor.exe tracing (SnapAPI installer build #2170 and higher)
create key HKLM\SOFTWARE\Acronis\SnapAPI::DWORD::"VssRequestorTracing"==1 to trace (disable with ==0)
log files will be saved in 2000/XP/2003: Documents and Settings\All Users\Application Data\Acronis\VssRequestorLogs\ Vista/Win7/2008: Users\All Users\Acronis\VssRequestorLogs\
Note: always collect system information after the issue has been reproduced. If Debug tracing, SnapAPI logs and VssRequestor logs are enabled, System Report (or AcronisInfo) will include all these logs.
The better way to provide backup plan settings is to export the backup plan as .xml file. See Export and import of backup plans. For Acronis True Image create screenshots of the backup plan settings: Creating Screenshots. Also provide exact details of what is being backed up.
