You can also set the maximum disk space used. This tutorial give more info:

The shadowstorage you can allocate with this command:
vssadmin resize shadowstorage /for=c: /on=c: /maxsize=x%
That would be a shadowstorage allocation for the C: partition. For 'x' I suggest between 10 and 15%. In lieu of x% you can also say xGB
