Okay, so my machine suffered a power loss this morning, and when Time Machine went to back-up it seems to have decided it can't trust the usual event log that it uses:
02/10/2014 14:56:43.351 com.apple.backupd: Event store UUIDs don't match for volume: Macintosh HD
It then proceeds to do a deep-scan, which is understandable I suppose.
02/10/2014 14:56:43.428 com.apple.backupd: Deep event scan at path:/ reason:must scan subdirs|new event db| 02/10/2014 15:04:58.809 com.apple.backupd: Finished scan 02/10/2014 15:10:53.693 com.apple.backupd: Found 402101 files (1.8 TB) needing backup 02/10/2014 15:10:53.747 com.apple.backupd: 2.16 TB required (including padding), 1.04 TB available
However, the required space estimate is far too high; my back-up volume's total size is only 3tb, and the total data on
Macintosh HD is around 2tb, this means that if I let Time Machine continue to run it's going to delete all of my backup history and then fail with a warning that it can't backup because there isn't enough space.
This is clearly wrong however, as the back-ups on the disk are valid, and should be matching most of the files found on
Is there a way I can get Time Machine to recognise this and adjust its estimate accordingly? If not then I'm going to have to start fresh with a new back-up, but that will take days to get up to date again!
I've just tried using
tmutil associatedisk -a and
tmutil inheritbackup to no avail, after an even longer deep scan it just starts trying to discard old backups again.
