A couple of weeks ago I was using my MBP Retina 13" which I use quite rarely. I have an external drive attached (it contains my Photos and iTunes Libraries as well as quite a bit of other data) which is included in the backup.
At the time I wasn't doing anything much, just reviewing emails I think. I think I had used it the previous day after unmounting the external drive for some lap work. I reattached the external drive and it mounted typically without event. Shortly after it set about a routing back up. After a long "Preparing your backup" it said, the backup is too large for your backup drive. The backup file currently is around 650GB made up of ~550GB on the external drive and ~100GB on the MBP. My backup drive is 1TB and has ~300GB+ of free space. I suspect TM has had a fit and thinks it has to do a large backup of something, but hardly anything has changed. Just the emails I viewed and some browsing. Do I blow away the sparesebundle (again) and reset the backup or is there another fix for this on going habit of TM?
