I am running into an issue where my C: drive on a Small Business Server running Exchange is running out of space on the C: partition. I have performed all of the normal cleanups recommended like log files, and WSUS. My mailboxes were always on the D: partition. While doing some digging, I found that a folder located \\windows\system32\backup is taking up almost 50 gb. The odd thing is that the sub folders are all stating less than a GB of data. What is stored in this folder and how can I shrink it? I first thought that might be a backup of the OS installed by Dell but the time stamp dates of the smaller folders are current and I guess it would not make sense for them to create a restore folder within the C: partition anyways. I am using the backup program offered with SBS to backup my server to an external NAS drive.
