Windows/Mac/Linux (All platforms): Online backup utility SpiderOak is
notable for its true cross-platform availability, but it also offers
(like Mozy) 2 GB of non-expiring free storage space and the ability to
run in the background, making persistent backups as you change the
contents of any folders you want to watch. The creators boast of a
compression algorithm that speeds up both uploads and restoration, and
unlimited bandwidth for paying customers, but its real value comes in
its simple interface and set-and-forget nature. For any user—but
especially Linux newcomers—who doesn't quite feel comfortable
setting up their own automated backups, SpiderOak is a viable option.
SpiderOak is free to download and create a 2 GB account; each 10 GB
increment after that costs about $5/month.
