Remove Snapshot Failed , Veeam Backup 4.0

[biker]

I get this message when backing up a 60 GB Server 2008 :

Initializing target session
RemoveSnapshot failed, snapshotRef "snapshot-1180", timeout "3600000".

The request refers to an object that no longer exists or never existed.

I have iscsi SAN and two ESX 3.5 U4 Hosts, no problems with other VMs.

What can i do ?

Hello, my guess is that Veeam Backup created snapshot during backup, but is unable to remove it, because it no longer exists. Some other application may have removed it. For example, someone could have delete it using the VMware Infrastructure Client. It would be best to contact support with this and they will assist you with resolution. Thanks!

I am getting the exact same error. There is nothing else that has access to my ESX cluster to remove the snapshot. Did you ever find a resolution?

Larry, please check with our support, they will look for this support case (if it was ever opened).

If I has this issue, I would first look through the vCenter/ESX event logs to see when this snapshot was removed, and see if this gives any tips on what has triggered snapshot removal.

Thanks!
