Recently I'm seeing my time machine backups get big. On a typical daily time machine backup, they've gone from a gig, to 5 gigs, to today... Time machine wants to back up 329gb. I've not moved huge files around. I've not fired up VMs.
So far it's backed up 17gb of 329gb. What's going on? I'm running 10.9 on a 500gb SSD
