Urbackupsrv remove-unknown deleted months of backups from all my nodes :(

HI

I am using 2.4.12 Server on Debian Jessie. MY nodes vary between Debian and Windows.

Yesterday I wanted to clean up unneeded backups so I ran urbackupsrv remove-unknown it was deleting some stuff but I could not tell since too much was happening in the llogs, now I check my daily backups, nothing is there and the server throws error in the log when I try to browse in the ui like this.

2020-01-07 12:02:40: ERROR: Cannot open "/media//URBACKUP/DESKTOP/191201-0047": No such file or directory (2)

It seems like it deleted at least 3 months of backups from all the nodes. The recent backups are listed in the web ui but all are empty and throws the errors similar to above.

I do not understand how this could have happened? It was clearly making backups, and they should all have beeen in the database.
