Today I’ve played aorund with urbackup and tried following
- setting up urbackup with docker on a linux server
- install windows 11 in a vm
- make snapshot (with the vm tools)
- install urbackup client
- play around with file- and image-backups
- goto last vm-snapshot (so I have a clean windows again)
- install urbackup client (downloaded from urbackup-web-interface for the specific client)
after the client is reconnected to the server (I had to confirm the a changed client-id) I can do backups again but I don’t see the older backups that I’ve done before going back to the snapshot.
To be precise: I don’t see the backups if I use “access/resotre backups” from tray icon - in this case I see only the backups that I did after the reconnect.
If I open the webinterface manually (as admin) and check the backups for this vm I see all backups from beginning.
Is this a bug or a feature? 
Using the Restore-Button from the web-interface seems to work for older and newer backups.
issue was also described here (but without solution): Unable to access previous backups after client PC formated - client - UrBackup - Discourse
This is how the admin-part looks
and this the result after using the tray-icon
