Possibly there are orphaned shadow copies and something is corrupt...

Have you tried to delete the shadow copies?  
File explorer - properties on a drive - Shadow copies....
There you can delete and disable the shadow copies....
After a restart of the Volume Shadow Copy service,, they should have zero size...

You can then have a look into device manager - Storage volume shadow copies (show hidden devices) and they should be empty...
If you see greyed out items left over (all others should be away), you have orphaned items. You can now delete all of them in device manager manually or use the tool DevNodeClean (an earlier tool from Microsoft - but possibly not available anymore....

Orphaned items need not necessarily create a problem but can be an issue...

After all Shadow copies are away, you may enable the shadow copies again (as set before) and see, if the error persists...

but on server shadow copies are not configured ?
If the shadow copies are disabled, you should not see any shadow copies in the device manager.
Check the device manager and make sure, you see hidden devices (grayed out items)...
To avoid left over orphaned items.

If VSS is disabled, this may also be the reason. It depends, how you backup your exchange... Some software rely on the Microsoft VSS, others have their own agents and writers...
Also possible that you have a permission problem, as I can see...
CsSnapRequestor::BackupComplete() - Call DeleteSnapshot()  [FAILED....


You can also use
vssadmin list shadows
to see the shadow copies..... (you may have a look if you find the GUID from above...)
If you can find the GUID, the backup system possibly has read permissions, but is not able to delete the Shadow copy...

or

vssadmin list writers
to see all shadow copy volume writers...
Do you see an "Microsoft Exchange Writer" there?
Any writers with Error (line Last error)?

ASKER

no there are no errors with writers.coomvault is using microsft vss, incremental is successful but full back up is failing with regard to above error I posted
So you use an Exchange Server Agent from Commvault?
If yes, does this agent have its own service?
Is the service running under a domain account?
Has the account the appropriate permissions?

See
http://documentation.commvault.com/commvault/v10/article?p=products/exchange_database/deployment.htm

Stated here: Backup Operator & Local Admin
And possibly - dependent from the backup method -- Exchange Permissions?
