I'm trying to figure out what's going on with my storage.
About This Mac > Storage shows that there's ~11GB of Backups.
Disk Utility seems to sort the same files as "Other".
Googling tells me that the backups shown in About This Mac > Storage are part of Time Machine (and that they will be automagically deleted if the space is needed), BUT Time Machine is disabled, and has never been used (and there are no /.MobileBackups or /Volumes/MobileBackups folders).
Running Disk Utility's 'First Aid' from the Recovery Partition says there's nothing wrong with the disk.
Also, Disk Utility reports two different sizes for "available" (in the same window). The difference seems to be the size of the supposed backups.

The "backups" no longer show up. Afaik I did not do anything.
