Is it possible to delete old TimeMachine backups (without screwing up the TimeMachine file/database)? I use a NAS to backup a MBP. The backups go back to September of last year. The space allocated for TM backups now has less than 10% free. And when TM finishes a backup, after the "Finishing" step, the "Cleaning Up" step takes quite a bit of time. (I assume this will continue to get worse as the free space diminishes.) I'd be OK with me if older backups were automatically deleted, but the Cleaning Up takes a bit of time and is relatively loud. Hence, I'd like to simply go in, delete backups before a certain date and free space. Is this doable? Thanks for any assistance.
