Okay, after rebooting, Roon server comes up. However, on the client it shows up as a (new?) core, asks me to connect, when i enter my username password, it then says that this server already authorised and says i have to unauthorise it. When i did that, it keeps me in a loop

I had a look to see if i could restore a backup. The backup location i can see was last updated on oct 16, but Roon can only find a very old backup from 2 years ago.
When i drill into the backup folders, i can see lots of recent backups e.g.

ROONBACKUP2
{“when”:“2022-09-07T02:00:01.5352655+01:00”,“machine_id”:“a2c55315-10c3-9fcc-b0c7-6d72cfc2c0d5”,“backup_id”:“1977e6a5-6867-4d12-b6c6-d5b59d8b21d0”,“broker_id”:“c4df42d4-5be5-4bcc-b0ca-9bb954249905”,“broker_version”:{“machine_value”:100801021,“display_value”:“1.8 (build 1021) stable”,“branch”:“stable”},“machine_name”:“AUDIOSERVER”}
…

So basically I am stuck:

The existing roon core seems to be running but when i connect to it, I’m prompted with a log in. After logging in, I get the screen above

If I unauthorise then I go back to the start, same series of events

If I try to restore from backup then it can’t see the recent backup

Please help!

After a further reboot, I went through this again, and after “unauthorise” it loaded my previous library and playlist, so all is right

I’m still concerned about the backups not working. Might set it to backup to a new folder?

I’d try an entirely different location, e.g. USB disk, and see if that works. In addition, double check that you have the correct path to the backup folder, and that you haven’t added the backup folder within an existing backup folder.
