Mountain Lion includes a feature to configure multiple Time Machine locations and to back up to those locations when they become available (plugged in external drives, accessible network drives, etc). Can 10.8 or any older version of OSX, possibly including third party software, be configured to back up different data to different locations?
Use case: I have 100GB of storage available on a cloud storage server, and a 250GB external hard drive. I want everything on my computer except media (photos, videos, music) backed up to both of those locations. I have another much larger drive that is accessible less often that I keep backups of my media on. Currently I have Time Machine configured with an exception list for the media locations and it backs up to all three drives (dumbly in 10.7, but smartly when I upgrade to 10.8) and then I manually make a backup of all the media directories using rsync occasionally. I would love for the media backup to be automatic when I plug in the large drive.
