Veeam Backups very slow.
Veeam reporting timeout errors on the VM level.
Veeam agent service crashing intermittently.
If Veeam is running very slowly, there could be a variety of issues, but a particularly interesting situation we’ve experienced is when Virtual Machine snapshots have been removed but Veeam still thinks they exist.
This causes a long timeout whilst Veeam attempts to delete a non-existing snapshot.
You can check for the existence of these bogus snapshots in the Veeam SQL DB by running the following query in SQL:
SELECT [session_id ,[host_name ,[snapshot_ref ,[vm_ref ,[snapshot_name ,[description ,[viproxy_id ,[proxymode ,[job_id FROM [Veeambackup.[dbo.[VmWareSnapshots GO
If veeam snapshots are removed in vcenter they won’t be deleted in the veeam database and we have to do this manually by running the following query:
DELETE FROM [VeeamBackup.[dbo.[VmWareSnapshots
