VSSADMIN command line problem

Hello

Noticed my C: free space was decreasing significantly and regularly.

To check system restore point disk usage, I ran the elevated cmd vssadmin list shadowstorage and got this:



Anyone understand why?

Oddly though, I was able to successfully run:

vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=1GB

This gave me back about 8GB of free space.

Both Microsoft Software Shadow Copy Provider and Volume Shadow services are running.

Returnil is currently off, if this makes any difference and the only other s/w running is Prevx Edge.

Thanks in advance.
