Home Forums Mac Software Mac Operating Systems Time Machine scheduled backups not running

Yes, my TM is on a FW bus (and the UPS on USB), although that FW bus - on a 'Late 2014' iMac - is of course connected via a TB<>FW cable/adapter.

Having said that, I have several times experienced the phenomenon whereby attaching a thumb drive via USB has 'provoked' TM into backing up spontaneously!
