You need to start with Applications –> Utilities –> Airport Utility. If you delete all of your hourly incremental backups for this system, however, I can proceed.
For example, if it prompted me with “Backup device has insufficient space for normal operation. Not so good, and it’s also not so good that Apple just leaves us hanging out to dry with no user-friendly path to solve the problem.
My Time Capsule is also a 500GB drive (yeah, it’s too small! That’s a separate issue) and out of nowhere Time Machine stopped backing up and kept complaining that it needed a bigger space for its incremental than I had available.Īpparently while it deletes older backups to keep things in rotation, if you have big enough blocks, it can get into a situation where it’s “stuck” and can’t succeed at backing up the current increment. In a curious twist of fate, this question came in just as I too was seeing the same problem, having recently upgraded the hard drive in my MacBook Pro to a huge 500GB device.
