Hi Guys
Had some work to do and finish to reinstall all nodes correctly.
So now i can say, that a reboot didnt solve the Problem :/
As you can see, there is some Backups there but not showing up under backups
Based on the information gathered from a forum post (https://forum.proxmox.com/threads/m...grade-from-backup-server-2-1-to-3-0-2.133369/), it appears that the error stemmed from transitioning the file system from ext4 to NTFS. According to the discussion thread, this file system switch results in the insertion of a different character instead of the expected one. Consequently, the backup system PBS is unable to properly recognize or process the backups due to this alteration.
now im able to see all my Backups again. Will try to recover some
