The Volume Shadow Copy Service (VSS) is a Microsoft product that
is built into Windows (2003+). It functions similarly to the Veritas Snapshot
Provider (VSP) in that it allows you to backup open files on a volume. VSS
is recommended for 2003, but both should function. I would try the
following.
1 – run chkdsk /f on the drive with the issue, disk
corruption can kill a shadow copy
2 – reinstall the NetBackup client and Maintenance Pack
(reboot if requested)
3 – Make sure there is enough free space on the drive you
are writing the vsp cache too (configured on master server)
VSP has known issues in older versions of NetBackup. That
vsp_cache file is a known issue if a backup fails unexpectedly. You can
use process explorer to release the handle and delete it manually, or manually
delete it after rebooting.

Subject: [Veritas-bu] VSP making server hung.
There
is one windows 2003 server and we are taking it's backup via VSP .
What
we have found that in last couple of weeks that when ever tha backup starts the
server gets hung.
PS:-We
have adequate free space in all of the drives.
When
i changed snapshot from VSP to VSS:-It started working fine.
Though
i know that VSS is recommended for 2003 servers but we were using VSP since
long and thuis server hang issue is very new.
Please
explain as i am a bit confused between VSP and VSS.
Does
VSP play any part in making the server hung?
Does
VSP deletes the nbu_vsp_cache after the reboot of the server ?
Or
it's something else that ia making the server hung ?
Thanks and Regards
