System Volume Information folder is filling up hard drive on my Windows 2008 R2 Hyper V Server

I have a Windows 2008 R2 Host Hyper V server with a guest Windows 2008 R2 MSSQL server. We got an alert from Solarwinds that the hard drive had less than 10% drive space. Which is concerning since we only have about 30GB of data on a 200GB drive.

I tool a look at the file system and as it turns out we only have 30GB of SQL MDF and LDF files.

Using a free app called SpaceSniffer I see that the 'System Information Folder' is 140GB.

Doing research I see that you can run this command:
vssadmin resize shadowstorage /on=F: /For=F: /Maxsize=4GB

To reduce the size. However, we are using Backup Exec 12.5 and I know it uses VSS to backup our Virtual Servers. I want to make sure that this command will not cause any undesired effects with our backup and that it is the correct command to run.

We have Shadow Copies disabled and have no "Previous Versions".

Thanks!

I am not sure about the command you have mentioned.
I remember, my colleague backup engineer used some commands to regain drive space.
 
please refer to http://www.symantec.com/connect/forums/backup-exec-stores-system-restore-points-system-volume-information-and-does-not-delete-them and see if that helps.

The files seem to be created when we ran Backup Exec backups.

Backup Exec uses Volume Shadow Copy service (VSS) and it is creating the snapshot copies in System Volume Information folder.
Check if you find anywhere in Backup Exec an option to store the snapshots.
