Rebit Disk Drive Backup
Rebit Disk Drive Backup is even simpler to use. Just plug in the drive (available in capacities up to 500GB for $220), give the built-in software permission to back up, and off it goes, continually protecting you in the background. By the end of January, the drive's software will get an update that manages backups for up to six PCs to a single drive (a good setup for people backing up smaller sets of data, but not for users who have multiple PCs packed with multimedia collections). The company also now offers its easy-to-use software on CD, for use with any external hard drive; the CD costs $50" at its Web site.
