Q: Mystery data?

This past Thursday (10/29) I did a fresh install of El Capitan (the upgrade from Yosemite was problematic) and after the upgrade, everything was going well. I then did some backups and drive images and stored them away on an external drive then last night, started a fresh Time Machine backup.  When I came into the office this morning, I noticed that my data consumption went from about 260Gb at 21:00 last night, to 336Gb this morning 0700 (on a 512Gb drive MacBook Pro Retina).  Where did the 76Gb of data come from?  Its showing up as "Other" but I'm not finding anything anomalous in my normal folders.  Most of the tools that help provide visibility to the drive by mapping it don't pick apart "Other". 

 

Has anyone else experienced this?  What did you find and what tools did you use to find the anomalies? 

 

Thanks!

MacBook Pro with Retina display, OS X El Capitan (10.11.1)

    Further digging unveiled a Time Machine snapshot for some unknown reason as the external drive where Time Machine backups are stored has been connected all along so I'm not sure how this occurred.  Needless to say, I'm trying to figure out what happened and disabled Local Snapshots going forward.
