I have a G5 Tower with Leopard 10.5.2 installed. I have a (now measley) 160 GB internal HD that I am using Time Machine to back up to a Maxtor external 250GB HD. My internal drive is almost full, and my backup is almost full. With a 90GB difference between the two, why is my external so maxed out? I realize that TM is keeping backups of items I deleted on my internal drive, but 90 gigs worth? You can't even delete items on the backup (maybe you can with TM turned off?). My question: will TM continue to backup my data until my external HD explodes? I am thinking about buying a 1TB Time Capsule or a ReadyNas drive (assuming it works with Leopard), but I assume these will fill up as well. Any thoughts or direction here is greatly appreciated!!
