SpiderOak Offers 2GB of Free, Cross-Platform Backup [Featured Download]
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.
