can an external portable drive be used for both time machine back ups and for additional storage or to sync files?
I use a seagate freeagent Go drive to keep a copy of important files. Files that I use with some regularity. I sync the drive every few days to ensure I have the latest. It is a old school method, but works well. I realize that not all things are "backed up" as they would be with a real back up, like time machine.
Can one device drive do both or should I use two different drives?
