The 300MB .vbk size is for the file server only. My whole environment .vbk is 1 TB.
So it can only handle 3 restore points. 4 is pushing it.
Storage Spaces is very interesting. Thank you for the link.
The problem is the remote PC OS is Win 7 Pro where the USB drive attached to.
Another thing that I'm worried about is data corruption when one drive goes bad. I might as well do a NAS at the offsite location.
Have you had any success with Storage Spaces?
I might have to do a little research.
