Unable to exclude files from snapshot

Backup agent for Microsoft Windows servers and workstations (formerly Veeam Endpoint Backup FREE)

Unable to exclude files from snapshot

Veeam Logoby jordpangborn » Mon May 04, 2015 3:51 pm

I successfully got Endpoint Backup to connect to my Veeam B&R server. I have been running backups on a handful of workstations. I am receiving a warning email from one of the workstations stating "Unable to exclude files from snapshot: Shadow Copy Optimization Writer is not available (see Windows event log for more info)."

The backups are completing and I restore files from them. But I can't seems to figure out this error.

Hello Jordan,
VSS service might be in stuck state. Does the PC reboot solve this warning?

Hello Jordan,

This used to be a known issue on servers... I can't really find a reference for workstations but can you check this URL http://blogs.technet.com/b/jonjor/archive/2010/02/18/scvmm-p2v-fails-with-at-40-percent-with-0x809933bb-or-0x80070539.aspx to see if it fixes your issue (don't worry about the P2V part... This is just ONE of the causes, there are others but normally the reg fix should be the same

Let us know

Thx

Mike

Mike's suggested link worked. I deleted a .bak in the profile list in the registry and then the backup ran successfully with no warnings.

Thanks!!!

I am getting this same error since updating to version 1.1.2.119. I have tried the steps in that ling but there are no .bak reg keys in that location. I have checked the event log and there are absolutely no additional details. Thoughts? Is this maybe a bug with the latest release?

Did you have this error before? If not, then I suggest opening a support case and investigate the reason for this change with our support team. On top of that, if it is a VSS error, then I would also suggest troubleshooting the VSS writers state.

In latest update we enhanced the mechanism of VSS optimization writer failure detection to let you know that files were not excluded from the backup. That might be the reason this warning suddenly appear after update.

Same issue here after most recent update on 2008 R2. Pre update it worked fine running daily jobs. Time to roll back ... :roll:

If the windows update is not successful it’s usually followed by another update :wink:

Dear colleagues!

I have the same problem. I backup TMG server with Endpoint backup. And 2 last backups made with an error: 06.11.2015 17:27:48 :: Unable to exclude files from snapshot: Shadow Copy Optimization Writer timed out (see Windows event log for more info). Nothing special in Event Viewer. All of the operations finished successfully. Only one special note was there:

What I have to do for resolving this problem? I tried to use solution with Registry, but nothing *.bak profiles in that branch of registry.
