I think I just found it. Ironically enough, it was my workstation. I
have an external drive that is normally plugged into my laptop for
files I need to transport I had plugged (and left plugged) this drive
into my desktop, which was being indexed and attempted to be backed
up. Apparently, this filled the filesystem, and the backup never
completed, but the files from the partial backup were apparently
stored somewhere. Once I umounted the portable hard drive, the backup
completed, and the drive space went back down to normal levels.
I have since commented out all of /media.
Thanks,
