I just signed up for an online backup plan with CrashPlan, something I've been meaning to do for a while. They are offering three years for the price of two this weekend, which finally tipped me over the edge. Only $150 for unlimited backup for all my computers, which is a great deal. Other similar offerings include Mozy and Carbonite, but I've read stories about people having issues with their "unlimited" backup not really being unlimited. I need at least a terabyte of backup for all my photos and videos, and I did quite a bit of research a while back on the various options and was most comfortable with CrashPlan. The other thing I really like with CrashPlan is that they will send you a 1TB hard drive (for a fee) that you can use to "seed" your backup – otherwise the initial backup is likely to take months with the amount of data that I have. I'll report back on how it goes!
