No mac at home. We use Time Machine at work. It backs up once an hour to a hard drive on our district network. BEST.THING.EVER! It was literally like pulling teeth to get the people I work with to back up their files. All they had to do to back up was to drag their files over to a backup drive that was installed on their desktop and drop them in, thus copying them to the backup server. Nope, too difficult. I sent emails, notes, talked to them in person, showed them how to do it, offered to do it for them, begged, pleaded and cried and they still wouldn't back up consistently. I love that now they are backed up and my job is much easier. Kinda hard to explain to someone that, sorry, their hard drive has crashed and they lost everything because they didn't back up. They think I'm magic and can make it reappear! LOL My boss would use his secret weapons and sometimes got some of their files back but not always. - At home I'm on a PC and just use Crash Plan... thankfully so as one of my EHDs went out the other day and being 100% backed up made it so much easier to live with!
