I am hoping to gain some suggestions and good experience with others crazed enough to do this: we are hoping to utilize a file vault for our main shared drive so that we can retain changed files forever, on a new server running 2012R2. We've considered Volume Shadow Copies, but I don't love the interface for it and I don't really want to make this available to all users either. What have you used that worked well? Free would be best but I'd like to hear everything.
Why not just use plain old backup? Mainly because we don't want to be stuck with intervals of potential loss, and that's how it works with our software.
Thanks for your thoughts!
