First , a quick and dirty option might be to turn off system restore and back on , it will probably wipe the system volume inforamtion file.( system restore can be quite useful for inept lazy people like myself so give it enough to back up your system.)
Otherwise the solution below shows how to set a max size for the folder.
My googlefu is on top form today.Advice from article linked below.

Now here are some commands that you could use in the Command Prompt console in administrator mode in order to view and resize the space allocated for SVI:
1. To see the space allocated and used for SVI:
- Open Command Prompt with “Run as Administrator” option
- Type in: vssadmin list shadowstorage
- You will see Used Space, Allocated Space and Maximum Space for SVI
2. To see the restore information stored therein:
- Use in the same console command: vssadmin list shadows
3. To resize the maximum allocated space:
- Type in command: vssadmin resize shadowstorage /on=[here add the drive letter]: /For=[here add the drive letter]: /Maxsize=[here add the maximum size]
- E.g., vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=4GB
- You will see a prompt confirming resize done
- You can check the status again using the command discussed in point 1 above
4. Just to get rid of the space already consumed, but sticking to the same size of max-size as before:
- Do actions as per point 3 to set the max-size t, say, 1GB
- If you check now, most likely you’ll see that used space is now 0KB
- Do the resize again and set it back to what it was before
