Unlike the existing 'domain backup online' command, this command allows an admin to back up a local samba installation using the filesystem and the tdbbackup tool instead of using remote protocols. It replaces samba_backup as that tool does not handle sam.ldb and secrets.ldb correctly. Those two databases need to have transactions started on them before their downstream ldb and tdb files are backed up.
