Hi farbuncle--
From the responses from others, are you talking about the amount of space
VSS takes up for System restor and restore points?
See:
Adjusting the amount of disk space System Restore uses to hold restore
points

Why do restore points in Windows Vista use so much disk space

From Jill Zoeller [MSFT]:
"It’s easy enough to decrease the shadow copy storage area, but doing could
potentially delete older shadow copies. If you need the free space more than
you need a long history of shadow copies, you can decrease the storage area
size.
Let’s say I decide to decrease the storage space on my D volume to 10 GB. I
would use the vssadmin resize shadowstorage command as follows:
V:\Windows\system32>vssadmin resize shadowstorage /on=D: /For=D:
/MaxSize=10GB
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool"
In case it's backup you're interested here's a very good article by
Christina Fok [MSFT], a Program Manager in the Storage Solution Division
of Microsoft that deals with System Restore and Backups:

Good luck,
