Shadow Copies out of control

Tags: shadow, copies
I have a backup server for that houses about 200,000 files of various sizes.  It synchs from other servers and has shadow copies enabled.  Its a 250gb drive with about half of it full.  Right now the shadow copies are at 25gb which is about 20% of the drive.  It only has SIX days of shadow copies and im wondering why it's taking up so much space.  I thought it only saves the block differences of the files and needs the original files to be able to revert back to a past version.  If this was the case i should only have a small amount of shadow copies, not 25gb.

I deleted a file and was still able to revert back to an older version even though the original was gone.  This makes me think its making a copy of the entire file any time its changed rather than the byte/block level differences.  I read that there is two types of shadow copies but cant find a way to set it.  Anyone out there with a lot of experience using this?  I want to have a month of shadow copies but at 8 days and 25GB im starting to really worry.
