VSS failed to process snapshot

Question

Hi, One of our NetWorker client backups recently began to fail with the following error: 5388:save: Failure status of writer Registry Writer - VSS_WS_FAILED_AT_PREPARE_SNAPSHOT VSS OTHER: ERROR: VSS failed to process snapshot: The VSS writer operation failed because of an error that might recur if another shadow copy is created. ** Says to look on Event and Error help link. (VSS error 0x800423f4) 90108:save: Unable to save the SYSTEM STATE save sets: cannot create the snapshot. 94693:save: The backup of save set 'E:\' failed. ctimgdbpsvr.ctigroup.com:E:\: retried 1 times. We are running NetWorker v8.1 and the client OS is Windows Server 2003 SP2. Any idea how to fix this? Thanks, Andrew

Check Error: 'VSS error 0x800423f4' when backups fail in Managed Online Backup for System State.  While different product, the reasons behind are the same.  Checking what it says in event log might help too.

To resolve the issue, the procedure is always the same:

- User "vssadmin list writers" to detect one which is not in 'stable' state. Unfortunately you will not see a missing one.

- Try to solve the issue. You will find tons of tips in the internet for this problem.

- Worst case: reboot the server. This will do the job as well.

i have done that. all writers are stable

This may well be but how do you know that you see all at all? - Compare the list with a server where which has the same roles/features.

Also make sure that no other snapshot exist.

Finally, it may well be that you might need to increase the disk space because there is not enough free disk space left. This happened to me once. And I remember that I did not receive any info/error at all.
