Linux Magazine: On-line Backups: Flexible Enough for Home & the Office (opens in new tab)

Just glancing through, I didn't see a mention of tarsnap, my favorite tool for backing up servers online.

Rather surprised that the article did not mention CrashPlan:

http://www1.crashplan.com/landing/index.html

Works under Mac, Windows, and Linux; everything is encrypted during transfer and storage; and it can backup to any computer across the LAN or WAN, including CrashPlan's own hosted service if desired.
