Hyperv Client - working but only with multiple errors

[uroni]

Looks like the same issue as in the other thread. Could you try the same work-around?

Hyper-V multiple disks: Request of image backup failed. Reason: Opening filesystem on device failed

Thanks for tracking this down to this extent. The cause may be a stray newline in the configuration coming from the client. If you are using a Linux server you can correct it like this for existing clients (requires restarting afterwards): echo -e "UPDATE settings SET value='ALL' WHERE value='ALL\n' AND key='image_snapshot_groups';" | sqlite3 /var/urbackup/backup_server_settings.db Will fix it on the server and client side with the next versions.

(You are on Linux, I guess? If not the powershell command is a bit below)
