I was just wondering how different folks use FD-ISR. For instance: do you run in Secondary SnapShot, Primary SnapShot, a Created Run SnapShot?? Here's my method: Run in Primary SS. This copies/updates to Daily SS every day. The Primary SS also copies/updates to Second Day SS every two days, and to Third Day SS every two days (one day after Second Day SS) Then there is Fourth Day SS which copies/updates every third day and finally there is Archive SS which copies/updates every Sunday from the Primary SS. With this configuration I'm able to go back to yesterday, the day before yesterday, the day before that, or the previous Sunday. I also have an Archive of Primary SS on an external HDD that has a copy of a clean Win XP install. I don't have a Test SS since I really don't test much SW. However if I -do install something and it goes wrong, I can go back several days to a clean SS.
