Here is my scenario. I have hundreds of Gb of photos on my iMac internal hard drive. I am currently backing them all up with Time Machine as part of my normal HD backup. My disk is getting too full, so I am in the process of moving older photo files off my internal HD to an external HD. I can copy this disk to another to create my own backup.
I wonder if I can have 2 separate Time Machine backups running. The first would backup my internal HD to an external backup drive A. The second would backup my external Photo HD to another external backup drive B.
It would be a simple solution. Is this possible? If so, how do I configure Time Machine to do this?
