You could also “attach to the server” (if you are running it in a container) and
Issue
urbackupsrv --help
which will list all the commands you can do …like
“remove-unknown” and “cleanup”
Hopefully you will find this
urbackupsrv man page useful.
PS - Tchak came up with a script to clean out the urbackup logs from the sqlite database. HERE is his/her/it/thing’s post.
