We have a client whose server has a 1.7 TB RAID 5 array that houses all of the data for their SBS 2011 server. We have VSS running on it because it works well for doing quick data recovery whenever a user accidentally deletes a file (which happens alot). The problem is that currently its taking up about 45 percent of the drive in windows, and it sucks up more and more each day. In a month or two the drive will be completely filled up if it stays with its current rate of growth, possibly less as I've noticed the rate has increased a bit. I don't want to disable Shadow Copy, just reduce the amount of storage it uses. I've listed the things I've tried below. As a side note the storage cap was set at 88 gigs, but for some reason its way over that, sitting at around 835 gigs currently (up 15 gigs from yesterday)
Deleting some of the older shadow copies - didn't affect storage usage
Set storage cap to 1 gig - didn't affect storage usage (returned to 10 percent after trying)
Used command line tool to delete some more of the shadow copies - didn't affect storage usage
Disabled Shadow copy completely (which according to windows deletes all the shadow copies) and re-enabled - didn't affect storage usage
I'll continue googling to see what I can find, but any help would be greatly appreciated.
