Does a solution exist for using another machine for backup that allows the user to "roll-back" to an older version. A common request from users is, "Can you retrieve the copy of this document from March that I modified in August, and was corrupted irrepairibly?" I assume there must be some sort of system that stores just the diff'ed data from Rsync, stores a base image, and then allows you to pick to what date the diffs should be applied to. Kind of like CVS for backups. This would make a second box a truly useful solution for backup without having to store a backup hard drive from yesturday, last week, last month, six months ago, last year, 2 years ago, 4 years ago, and 7 years ago (for FDA).
