PVE runs a bunch of backups after unscheduled power cycle

I have a 3 node cluster with HA off. It runs pretty well and does as expected most of the time except when power goes out. Anytime the cluster has an unexpected power cycle or outage (like losing power to the office), when the systems come back online, Proxmox VE starts a surge of backups of a bunch of VMs and containers. Even if the cluster was only off for a few minutes (and those minutes weren't during a time backup was meant to happen).
Is there any reason for this to happen? What might be causing it?
 
Was this ever solved ?
I have 3 backup jobs set to run during the night.
All of them have "Repeat Missed" unchecked and yet every time power goes off and on during the day - all backups jobs are started.

could you post the full journal of that boot ("journalctl -b")?
 
I lost power again and when I booted up - it didn't make another backup.
I guess that journalctl -b will show details only of that last boot ?
Any way to extract previous boot details ?

I found it in the meantime - but thanks :)
Attached log I cleaned from lines that contained any of these words (as they were repeating so many times the log was too huge - I must work on them as I had no idea). I also removed the domain. Let me know if you need the full version.
