I was recently turned on to CrashPlan. It is pretty cool for how flexible it is; you can backup several PCs in your house to a single point, or to each other, but the coolest feature that I'm most geeked on right now is the ability to create your own off-site backup by backing up your PCs to another PC, located anywhere in the world. For example, I just setup my PC to backup to my lady's PC at her place. If I wanted, I could also setup my PC to backup to my mom's, etc. I'm considering implementing this for a few of my business clients who refuse to use a cloud-based backup for security concerns, but they'd be OK with keeping a PC at their home to backup their office. Anyone else??
