I see. With 10.7 and earlier there is no way to "temporarily" adjust the sleep timer. If a permanent long sleep timer is not desired, then it would require the RunBefore script to set the sleep timer with pmset and a RunAfter job to set it back to normal following the backup. My Mac clients are in and out of the office seemingly at random. It is not uncommon for the users to leave in the middle of a backup. Up grading to 10.8 and using caffeinate seems to be my best option, else they will be left with a long sleep timer while traveling should they leave in the middle of a backup. It is a real pain trying to backup these "road warrior" clients. > >> You wouldn't happen to know how to enable WoWLAN on a Mac would you? > > Again, easily set in System Preferences or using pmset from the command line. > If you’ve got a lot of Macs, Apple Remote Desktop is your friend here. > (“Send Unix Command” to the whole fleet) Thanks, Joe. > > Cheers! > -Joe Rhodes > > >> For those that are backing up OS X clients, you may have noticed that 10.8 >> Mountain Lion and later is much more militant about having machines sleep. >> Even if you issue a WOL packet to start a backup, they still fall back >> asleep pretty quickly unless there?s someone actually using the mouse and >> keyboard.
