Hi!

We have a Proxmox cluster and 2 backup servers.
PVE 8.0.4
PBS 3.0-1 internal pbs syncing with external PBS 2.4-1

I have made many different restore attempts (changing VM ID, different servers from the cluster, both backup servers) but always get the same error message.

Do you have any idea what could be the reason or how to restore an already deleted container from the backup?
A backup restore of an existing KVM or container works fine.

The error message is always the same:

all Backups from this CT are verified, so this can not be the issue.
