I have a Macbook Air and the SSD is nearly full. Photos take up a lot of space. I am ready to migrate the Photos to an external HD- i'm hoping the process is easy. 1) I have a Time Machine HD which has been partitioned to include a second partition with 200Gb storage space. Can I put the Photo library on that partition easily, and if so, will it back itself up to Time Machine, even though it is on the same physical drive (but different partition). 2) If it is a bad idea to use the partition for Photos, if I buy another HD will Time Machine back up that photo library? 3) Is there a better way to be doing this? Thanks!!!!
