VSS error 521 when attempting backup
- by blade
Hi,
I have backupassist and I attempt to run a backup, with VSS service running. However, I get this error in Windows Event Log:
The backup operation that started at '?2010?-?04?-?30T01:51:15.601000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
Code: 521.
The error in backupassist is:
The backup operation stopped before completing.
Detailed error:
ERROR - A Volume Shadow Copy Service operation error has
occurred: (0x80042336)
The writer experienced a partial failure. Check the component level error state for more information.
Log of files successfully backed up:
C:\Windows\Logs\WindowsServerBackup\Backup-29-04-2010_18-51-15.log
Log of files for which backup failed:
C:\Windows\Logs\WindowsServerBackup\Backup_Error-29-04-2010_18-51-15.log
A Volume Shadow Copy Service operation failed. Please check "VSS" and "SPP" application event logs for more information.
ERROR - A Volume Shadow Copy Service operation error has

Any idea how to fix this? I work in a company with server engineers, they all state of having no problems with 2008 and VSS (though in the company we use predominantly 2003). Without vss working, I assume no backup application will work?
Thanks
