Guest funkyd Posted May 22, 2008 Posted May 22, 2008 I am using Win2K3 R2 SP2 with Symantec Backup Exec 12 with Continuous Protection that utilises VSS. Every once in a while, I get these errors in my event log along with a mass deletion of nearly all my snapshots on the volume - maybe a dozen or so: Event ID 10 Volume Shadow Copy Service information: The COM Server with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} and name SW_PROV cannot be started. Most likely the CPU is under heavy load. [0x80080005] and also: Event ID 12292 Volume Shadow Copy Service error: Error creating the Shadow Copy Provider COM class with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} [0x80080005]. and then finally: Snapshot created on '5/14/2008 9:00:31 AM' for server 'XXXXXX', volume 'F:\' containing backup destination 'backup server' has been deleted by an external source. No other backup software is in use - error 10 indicates that the server is under heavy load but there is nothing running at the time these errors are logged - not even Symantec. Symantec say this is a VSS problem as it is not their software that is deleting the snapshots. I have seen a couple of KB articles 923160 and 826936. The first doesn't really apply as I am running SP2 and the second sounds right but I can't be sure - I have applied the second hotfix and changed the size of the VSS storage area to 1.5GB instead of 300MB. I am using a dedicated volume for snapshots which always has around 100GB of free space and I would estimate that my snapshots contain about 10GB of changed files. Any help greatly appreciated!
