Mozy - If Dropbox is where you stash the stuff you're working on or enjoying at the moment, Mozy is the backup service that saves everything for when your system goes black on bootup. The free accounts for PCs (and Macs) offer 2GB of free online space, and with the really smart filtering tools, you can have Mozy crawl your whole system and back up financial documents, Excel sheets, and any file with "Rick" in it. If you spring for a monthly unlimited plan, Mozy is a smart whole-system saver, one that doesn't eat bandwidth when you're using it, and works when you're not working. [Download]
