Thanks Todd, -very informative.

Let me make sure I understand. If I use your snapshot schedule:

snapshot002 at 8:00 - 12:00
snapshot003 at 12:00 - 18:00
snapshot004 at 18:00 - 23:59

I can:

a) do file level restores from any snapshot with admin privileges
b) backup snapshot004 at 00:00 and capture all changes made during that business day

Sound about right?

Thanks!
