Veeam Backup & Replication 8.0 Hangs at “Deleting Helper Snapshot”

Filed under: vmware — npd @ 8:57 am

During a replication job to move a few VMs to new infrastructure (ESXi 5.0 to ESXi 5.5 in 2 different VCenters), watching the progress bar anxiously as the client is very sensitive to I/O interruptions and I have bad luck with snapshot deletions, we hang here, at “Deleting helper snapshot.”



I do have patience for these things but when we look at the previous job for DC2, we can see that this task finished in a reported 9 seconds and the job completed shortly thereafter.

Anxiously I review the logs inĀ C:\ProgramData\Application Data\Veeam\Backup\<Job_Name> and confirm that there have been no additions to the log since this last entry.

Next I review disk usage graph in VSphere console and verify that there is no I/O intensive operation occurring. There is nothing to see here.


Finally, as I prepare to open a case with Veeam, the job finally finishes successfully as shown here:


Success! Strange that it says it only took 5 seconds when it really took 2 hours.

To compare results, I looked at the log file for the job which says it took 9 seconds, and see this in the logs. Look at the discrepancy between the highlighted lines.

So, don’t worry if you are hanging at “deleting helper snapshot” in Veeam. There will be no progress on the screen and I don’t see any way to measure the progress. Relax, don’t stare at it, don’t cancel the job. There should be no impact because of this. I had no dropped pings to my server and had no I/O lockup as when deleting other snapshots.

Hope this helps!
