I had to do a Roon restore yesterday and upon successfully completing this process, all my favourites have disappeared (99% of all albums, tracks etc). This is very disappointing, especially as I schedule regular backups.
Did you check the date of your last successful backup before doing the restore? Maybe you restored an earlier backup or the restored database can’t see your media files.
It’s be helpful is you shared more information about your setup.
I’ve tried the same restore point twice & consistent results (still no favourites). I’m going to go back further now and see if this is an issue with the latest build backup point.
OK so foolish me. I’ve found the problem. When I did a restore, it seems to default to a different user profile. I noticed this when using multiple Roon clients.
