Had a little problem on my server and desktop that VSS was eating up all of my diskspace. If you have this problem just run this command (in Administrator Mode CMD prompt) and you’ll get youre diskspace back.
“vssadmin Resize ShadowStorage /For=C: /On=C: /MaxSize=900MB”
!!!NOTE: be aware that when you change the max VSS size you will lose some restore previous versions data. !!!!!
