Backup fail sporadically

[chrigiboy]

Hello,
we sporadically have the error messages below. At around 11pm, about 10 Proxmox servers start backing up. However, we have backup errors all the time. Last night, for example, 5 out of 10 Proxmox servers had a backup error. The errors occur at different times. At the same time, other servers can successfully run the backup.

=> Backup was faulty, nevertheless the backup exists and is now also verified.
