Veeam Temporary Snapshot not deleted [Case# 02453931]

Post by tinto1970 » Jan 04, 2018 10:21 am

HI folks,

i've noticed in many vSphere installations i manage that snapshots remain active after backup.
I've opened the case 02453931 in this scenario:

Veeam 9.5U3
VCSA 6.5U1d
ESXi 6.5U1

it actually should be a vmware issue, because in task list i see that Veeam sent the command "Remove snapshot" and the Hypervisor replied "completed".
The worst thing is that a long snapshot chain can be created, and the removal process heavyly impacts VM performances during process.

has anyone seen this too?

Correct, we have seen such behaviour previously. Actually, we've even implemented a feature (called Snapshot Hunter) solving this issue. It finds and removes orphaned snapshots. Thanks.

Snapshot Hunter says it only detects phantom snapshots. Which are snapshots that vCenter is not aware of.
What about all the times Veeam leaves snapshots attached to a backup proxy and they still show in vCenter?
This has become an issue for me since migrating to vCenter 6.5, didn't see this issue on 5.5 at all.

Can you provide us with your support ticket ID for this issues, so that we can investigate the reasons of why snapshots are stuck on a backup proxy machine? Thanks.

I'm having the exact same issue. The snapshot chain will continue to grow to a depth of 20 and then no more can be created. Once that happens the backup fails and I have to go to vCenter and manually delete all of the snapshots. After cleaning them out the backup begins working again. I did not have this problem until switching to the vCenter Server Appliance. For some reason the snapshots aren't being removed during the backup process even though vCenter says that they are.

- Veeam Backup & Replication 9.5.0.1536
- VCSA 6.5.0 (8024368)
- ESXi 6.0U3 (5224934)

Not yet. I pulled the VCSA out of the backup list for now. I want to create a separate backup just for this VM and see if that makes it behave any differently.

Kindly, create your own support ticket and share its number here. The previous case was closed by the customer without any final conclusion about root cause made. Thanks!
