How to force a new 'clean' Time machine backup
I ran out of space on my backup hard drive.
I wanted to wait a few months before buying a time capsule, so I thought I could save some space on my backup by starting again from scratch.
I erased my external backup hard drive and threw everything in the trash and renamed it.
However, the time machine backup still seems to want to keep all the versions, making the required backup size too big for my external hard drive.
How can I force TM to zero all its backup info out and start from scratch with a clean new backup.
