Ever since Lehman Brothers, the default has definitely been making a comeback. Let's see how much money I lost today.

I have also used Mozy, specifically MozyPro, for my company, for more than a year.
I had a terrible experience with it, the client initially worked well, but is so badly written that as you get to multi-gigabyte volumes, the incremental scanning kills completely stalls the OS.
So: whatever you choose, test it for a while. And, most online storage services have encryption, including DriveHQ, which I switched to. Works fine so far (6 months).
