Time Machine is saying it can't complete my backup b/c the disk is full. It requires 108 GB, but only 67 GB are available. I've deleted a bunch of files and restarted, but I'm still getting the same message. I have a 1 TB backup drive and Time Machine options it says estimated size of full backup is 792 GB. Not sure what else to try here. I've excluded even more items and nothing happening.
