I recently acquired lots of movies and my hard drive capacity is being tested. I have a 2TB internal drive in my iMac and use about 1.7TB. I have 2 external drives, an Airport Time Capsule 2TB and a 1.5TB drive. I was using my 1.5TB drive for Time Machine, but now it is too small to back up everything. I use the 2TB drive to do a daily backup of the entire drive (using SuperDuper). Issue 1: I am adding more movies and soon I will run out of space on my internal drive. Issue 2: I would like to use TM to do a complete backup. I want 2 backups of everything, especially my music. If I lose my music, I have no way of getting it back and it's a lifetime collection. I ordered a 2TB drive from amazon for $125. I was going to replace the 1.5TB drive with this and use it for TM. I would then put all my movies on the 1.5TB drive and take them off my internal drive, freeing up quite a bit of space. I am not overly concerned about backing up the movies. Anyway, I figure there's got a be a better solution. And I'm not sure if I can daisy chain the 3 external drives. Any suggestions?
