Veeam backup temporary snapshots sometimes not getting removed

[holden j caufield]

There is no rhyme or reason as to when the "veeam temporary snapshot" is not removed. All the veeam backups show success but on a whim I've been checking the SAN and browsing the datastore and I see these name_of_vm_001 (or similar naming convention, I forget exactly) folders and there are snapshots that are orphaned and not removed.

I see this also in vcenter snapshot manager. If I don't manually delete all sometimes these snapshots keep building. My next question is can I just manually delete all or is the best practice to take another snapshot then delete all. It's pain to have to check each vm every week for this.

The issue is with the VMware VDDK and was supposed to be fix in a new version released last February. All of the backup vendors have to roll the fix into their software, so you'd need to check with Veeam support to see which version has it.

As far as best practice, vSphere 5 (or maybe it was 5.1) has a consolidate feature. You can use this to get rid of all the snapshots, as long as there isn't a lock on the file(s) from the backup server or from the vSphere host. If you don't have the consolidate function, then the method to use is the second one you described: take another snapshot and delete all.

We talked about this a little bit in another thread here:

You should try to identify the root cause instead of continually wasting your time.

If no Veeam jobs are running, you can delete the unneeded snapshot manually. Generally Veeam`s Snapshot Hunter deletes orphaned snapshots with no issues.

What version are you at? You may also contact their support if the issue is persistent
