Hi lorraine,
Thanks for posting back.
Let us refer to the following steps to troubleshoot the issue:
1.Installed the following Hot fixes
KB913648 " "http://support.microsoft.com/kb/913648/en-us> : A new Volume
Shadow Copy Service update is now available that fixes various Volume
Shadow Copy Service problems in Windows Server 2003
KB924749 " "http://support.microsoft.com/kb/924749/en-us> : Event ID 2021
is logged even though lots of non-paged pool memory is available in Windows
Server 2003
KB925903 " "http://support.microsoft.com/kb/925903/en-us> : You are forced
to replicate a large file from a Windows Server 2003 SP1-based computer
across the slow network links when small changes are made to the large file
2.Disabled compression on the Drive
3.Enable shadow copies on all drives included in the backup.Adjust the size
of the shadow copy to accommodate the backup.
1) Ran a backup after deleting the oldest 2 snapshot sets
2) Changed the setting of "Maximum Size" "No Limit" to "Use Limit" and set
it to 3071.
3) Once the backup is executed well, changed this back to "No Limit".
Changed the 'settings' of D: drive from "No limit" to "Use limit" value
3071MB
Tested a shadow copy,then do full backup again.
Changed the 'settings' of D: drive from "Use Limit " to "No limit"
4.Please refer to the following KB to verify if it is related hardware
backup device,compatibility issue between hardware and OS
Windows Server 2003 cannot perform backup jobs to tape devices on a storage
area network
http://support.microsoft.com/default.aspx?scid=kb;en-us;842411
you can Connect a USB drive to the server and ran the SBS backup wizard to
backup everything (system state, C:\, E:\, and Information Store).what's
the result? if USB drive work,indicate that it is related to your NAS
backup device.
5.if issue persists,please install windows 2003 server SP2
6.If you schedule to back up to a hard disk, does the issue occur?
Finally,I would like to confirm with you if you have manually performed
full backup to NAS device successfully as my suggestion 1 do in my previous
response, if so, that means manual backup have no problem,just scheduled
backup have problem.
This is important to identify the issue.
If issue still occur,please send me the backup log as I have mentioned
before.
I appreciate your time. I am happy to be of assistance and look forward to
your reply.
Have a nice day!
Best regards,
Jacky Luo (MSFT)
