Problems with NT Backup

One of the SBS 2003 servers I support is having a backup problem.

We use NT Backup to do a daily backup (around 20Gb) to a 500Gb USB drive and this has worked perfectly for 6 months. Now we get the following error message:

=====================<BEGIN NTBACKUP LOG FILE>=====================
Backup Status
Operation: Backup
Active backup destination: File
Media name: "Small Business Server Backup (02).bkf created 19/02/2009 at 11:41"

Volume shadow copy creation: Attempt 1.
"MSDEWriter" has reported an error 0x800423f4. This is part of System State. The backup cannot continue.

Error returned while creating the volume shadow copy:800423f4
Aborting Backup.


The operation did not successfully complete.


=======================<END NTBACKUP LOG FILE>=====================
NTBackup finished the backup with errors.

I've searched the EE database on "0x800423f4" and see I'm not alone.

1. We're on SP2, so it's not the service pack.
2. I re-registered the DLL and that didn't work.
3. There are no open files when the backup is running.

Any ideas please.

    Run two batch files, one before the bckup starts & one after it completes. The first one should run:

    net stop vss

    The second one should run

    net start vss

    Try this & if it works, then VSS is probbaly running or doing something at the same time or during your backup job.

    VSS in run started in Services.

    Doh!! Should read "VSS is NOT started in Services.

    Accepted Solution

    If I test manually and exclude System State it works fine, but included it reports the same error message.
    Any ideas - besides excluding the system state??
