It was my understanding that timemachine runs every hour. But I notice every morning that timemachine has not run for several consecutive hours (see picture). and after 1 hour... I wonder if this is correct (maybe it is) ?? I understand I did not use my iMac for those hours, but as I do a FULL disk backup, should timemachine not indicate the last backup was done 1 hour ago ? Or is this something to do with preferences ? Any knowledgeable insight welcome.
