My new plug is for CrashPlan. The software is awesome. It’s the same software used by a commerical vendor that my company uses called Metiix (although the consumer version, CrashPlan, has more features…..go figure.) It’s cheap – $49.99 per year for unlimited data for one computer (though, if you are techy like me you can just push all of your data to one machine and back that up.)
Upload speed is not great, but I’m resigned to the fact that none of these vendors have good upload speed, except maybe https://www.sugarsync.com/, which I use as well, but only for most critical data because it’s too expensive for all of my stuff.
