By the way, Ken and Rob, do you think this script/query would also work for 1.9 => 1.9 scenario? I mean delete a lot of old course bacups on Moodle 1.9.x?
Also it seems that when the mdl_files table (or you just kept accumulating a lot of older course backup files), it would slow down the SQLserver. Is this still the case in the latest Moodle 2.3.x?? Thanks!
