Backup in mode Snapshot fails sometimes

[Kaboom]

Good morning!

When making backups in Snapshot Mode some containers are having problems. I have to change the Mode in Suspend and then the backup will be succesfull. But I don't want it to Suspend because then the server will go offline.

Running 10 servers with latest Proxmox and Ceph.

Error message when starting backup in Snapshot Mode:

How can I delete these files that exists? Where are these located?

Thanks in advance!
