Hi - I am interested in purchasing FDISR and I wonder how it compares / contrasts to other products. I am looking for a product that can snapshot my system - which I can use to recover to a time point, let's say; prior to a software install; or a corrupted registry entry. I am much more interested in system level files (on a Win XP Pro system) then I am in my data files (which I copy off to an external disk every several minutes as they change). It seems that FDISR has the ability to deal with open system level files; vs. Horizondatasys's other product, GoBack. Years a go, I used a product called ConfigSafe (this was win96/win98 days) which I liked because it allowed me to compare snapshots or compare current system to last snapshot. This way I could see hcanges made in the registry since the last snapshot. Does FDISR enable one to do this? Any help in understanding these products that will help me make a decision is greatly appreciated.
