Backup Strategy?
I have a new 320 GB iMac, and added two 750 GB external drives. Currently, I’m using both externals for Time Machine backups. I now want to use SuperDuper! to also create a clone backup(s).
My original thought was to continue to use one of the externals for a Time Machine backup, and delete the TM backup on the second external and use it as a SuperDuper! clone drive. Given that the externals are more than twice the size of my internal drive, that seems like I’ll end up with a SuperDuper! drive with a lot of “wasted” space.
Does it make sense to erase and reformat the second external into two partitions—a 320 GB volume for the clone and a 430 GB volume to “archive” files I no longer “need” on my internal (but which I don’t want to permanently delete)? My objective, of course, is to achieve the "best" backup "insurance" while making most efficient use of available drive space.
