Upgrade your client ..there are know VSS bugs (I think anything above
5.3.3)

There has been a few discussion threads, in this list, on Shadow Copy
problems. There are other things to check beyond this.

Go on the mailing list archive and search on the below error ...

TSM Backup - Volume Shadow Copy Failed






Hi All,

Please review the error reported below on the dsmerror.log files. I have
lots of these error lately on Windows machines that are running Windows
XP with no service pack.

 "ANS1950E Backup using Microsoft volume shadow copy failed."

Both client and server running TSM version 5.3.0.

Appreciate your feedbacks on above issue.

Regards,
Dinesh Pahari
