I would like to utilise some of the vast unused space on the internal drives of two iMacs as backups for films. Is this possible? If it is possible then what is the downside? Could such a partition be later removed to restore the space to OS X? I do not want to go through the disk-erase and OS X re-install operation!
My concept is to use SuperDuper to create a sparse image (which permits smart updates) of some of the films on a USB 3 external drive. In practice I would use say three sparse images for ease of management. iMac 1 (2012) has 1TB with Fusion Drive. iMac 2 (2009) has a standard 1TB drive. I would prefer to use the Fusion Drive iMac for the backups. Both iMacs have Mavericks installed, and hence should also have Recovery partitions. (If an OS X upgrade or Boot Camp can install partitions, why not me??) I have assumed a partition would be needed, but can a sparse image simply be used as a file within the ‘Macintosh HD’ OS X startup volume structure?
