Since a few days, my backup onyl work on approx 2 of 5 days. The Backup stops on the very end of the backup-process. II back up a few VMs, but only one at a time. There is at least a 1-hour break between backups.
The source is on a SSD (PVE 8.4.14), the destination is an a harddisk (PBS 3.4.0).
Please see the log:
Any ideas how to fix this?
