I downgraded my Dropbox to a free account and signed on with Mozy.com. Dropbox is a great service for backing up and syncing my writing between two computers, but for backing up my family photos and videos online it just doesn’t work. There’s no way to back up files without also putting them on both computers, and my laptop doesn’t have space for all those files. With the free 2GB version, though, I back up my writing and everything is good.
Mozy.com offers unlimited backup from one computer for five bucks a month. That works out perfectly: I save the file on my laptop, dropbox copies it to the desktop (as well as keeping an online copy) and then Mozy backs it up again. I also have a 2 TB Time Capsule drive running Time Machine at its regular pace.
I hope that covers it.
Only downside is the initial backup to Mozy. I started it yesterday afternoon, and the download window says it still has three days, thirteen hours to finish.
