I'd like to configure Shadow Copy for SBS 2003, but I'd like to better understand how it works before enabling it. I have created a shared folder on the server, D:\ that contains about 33GB of files. If I enable shadow copy on this drive, how much more space is that likely to take up? And do the shadow copies get backup up with the backup utility? If it doesn't take up too much space, I'll just enable it on the D:\ drive. But is it possible to enable it on sub-folders on a drive, or does it only work at the drive level?
