Can this program be used as a virtualiser? I ask because one of the features listed on the rollback rx website claims that you can Roll-back, yet recover files from your "future" snapshot(s). So theoretically i would be able to take a snapshot surf, finish surfing, take another snapshot rollback keeping the files I wanted and delete the snapshot I took after surfing. Is this right? Wouldn't this allow me to utillise Rollback as a virtualiser? What are the disadvantages to using this as opposed to a dedicated virtualiser like returnil or shadow defender? For that matter can either returnil or shadow defender be used as backup software in a similar manner to rollback rx? All of these products use ISR technology right?
