Hey,
This morning I noticed that at 03:58 this night my server terminated all sorts of processes. /var/log/syslog says:

The time seemed suspicious to me right away. Rightly so: It coincides with the time when a backup was created via rsync to Backblaze. This is not the first time this has happened and it only happens when a full backup is performed. The backup size of the full backup is 78GB. Does this size cause the backup to consume so much resources that the system has to automatically stop other services?
