Cross Platform (Mac, PC, Linux) - CrashPlan gives you freedom in choosing your backup destinations. Back up your new Mac to your old PC, your laptop to a friend's desktop, whichever you want. Worried about using too much space on a friend's computer? No problem! CrashPlan will use an attached USB drive to hold your files."

Even the best laid backup plans often leave out the off-site backup component.  This is especially true for home users.  The off-site options out there have often had certain limitations.  Most involve a monthly fee and require you to actually trust the company you are backing up to.  My off-site plan has been to rotate USB drives to an off-site location once every few weeks along with daily at home backups within my network.  For the importance I place on my data, I think this is adequate, but if your needs require something a little more robust and you have a friend you can backup to, a $24.99 one-time fee is all it takes.
