Unable to exclude files from snapshot

Post by jordpangborn »

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/archi ... 70539.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:

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.

Hi,

In order to open a case please follow this guide. Btw, which version do you use? Please make sure that it's the newest available.

Thank you.

Hi Anna,
Unable to exclude files from snapshot
Just to clarify, are you running the entire pc backup / volume level backup mode or it’s a file level backup with enabled exclusions? As Pavel said, the support ticket should be opened thru the Endpoint’s UI (Control Panel > Support tab > Technical Support) - it collects the application logs automatically which makes the troubleshooting a lot easier.

P.S. Please upgrade your Veeam Endpoint Backup to the latest available version. You can download it from the website, all further updates can be installed thru the application's auto update functionality.

2Pavel: I have newest version - 1.1.2.119, but I can't to choose it in the case.

2Dmitry: I do the file backup with exclusions, right. I couldn't use that server for opening case in outside web server, excuse me. How could I gather logs by other ways?

I suggest you to choose any version and submit the case. I believe that you will be able to explain everything to your support engineer when he contacts you.

Re: Unable to exclude files from snapshot

Understood – thanks! You can open a case from any other machine connected to the internet and with VEB on board (just highlight it in the case). Another life hack is to open a case at customer care portal but refer to any other Veeam product - just ask to be redirected to Endpoint support team in case details.

To tell the truth there is no need to open the case for this particular error/ warning since backup is eventually created. The error is displayed when specified files cannot be excluded due Microsoft Shadow Copy Optimization writer being inactive or timed out. When it happens VEB cannot leverage it to exclude the specified files from the previously created snapshot and you got this notification in backup session, however created backup file is fully operation.

Thinking of possible workarounds:
- The best way to utilize exclusions is to select several big files. Selecting thousands of smaller files will probably cause Microsoft optimization writer to fail.
- Issue might be fixed by rebooting the OS at some point.
- If the exclusions are not critical, switch to volume level backup / entire pc backup mode or disable the file level exclusions. These to modes support the bare metal recovery while file level recover does not.

I understood, but we can't optimize this backup from file to volume: here is huge volumes and we don't have possibility to storage all of these volumes. That's why we use file level backup for this server.

Understood – thanks! And is it possible to change the exclusion list, so it consist of a very limited number of files? Thanks

I optimized it. There are a lot of logs, cause it's a TMG.
We restarted this server on weekend. The issue wasn't resolved =( And I wanna ask about incremental backups: is it all right if the backup is only incremental after first full?

Hi Anna,

How many files do you have in exclusion list this time? VEB runs forever incremental backup mode so first full is always followed by incremental restore points.
