Hi Ronnie,I think I mentioned I work away. Since the below email, I've been away for a swing and returned this Thursday. First thing I do is get my MacBook to do a backup with nothing else running just to bring it up to date in TM. I'd moved some video files in the time away so expected a sizeable backup and after about 20 minutes Preparing Backup, it set off doing that backup of around 20GB. Stacks of space on the backup drive (+900GB unused). Next morning I checked and it had 'finished' but said latest backup was in March 2016. I thought here we go again. Had to have some surgery (eye) today but got around to look further this afternoon, subsequent backups couldn't find the disc. All other MacBooks in the house are backing up nicely with no hiccups tothe main TM 3TB disc - all since I moved to Sierra and had the FileVault problem. That problem is resolved and not recurring fortunately. I unmounted the backup disc (it's a 2TB external drive connected via Hub to the 3TB TC and is unique to my MacBook in the house). Then remounted and restarted backup process by selecting the right disc again. A long Preparation period ~1 hour then it set off backing up again - ~20GB again. Upon that 'finishing' - Latest backup was November 2015! Then I get warnings saying last backup was 500days ago - no kidding Time Machine!!
I have a CCC backup of the whole MacBook/external drive (800GB in all) - I am thinking I'll blow away the Sparesebundle file and start again. It shouldn't be this hard. Probably a simple fix but I have 1 backup to revert should I have a MacBook HD failure so little risk for me. That will be a lengthy process as the deletion will take most of a day and the Firsttime new backup same again for full pass. This would be a bit of a 'Neanderthal' approach but will work- I've done it before as you probably recall - in the past due to my own error - but I've learnt to have kid gloves with this TM thing. I wonder if any other tips before I resort to the Primitive approach. I have 10.12.4 Sierra and a MacbookPro Retina.
