@JBS true.
@David, I think I see exactly what they are doing. Not sure I would do it that way, but I am not there.
What I first read was this second server being updated quite often, and you simply change the path of each client if there is a problem. That would BE cool! I think though, they are advocating making backup images, then if your first server "Domain Server_first four letters of your last name_SER1 (I will just refer to Server1)Server1, goes down, you restore from the latest image and use it and then restore II while working.
I don't know how many progress notes you do an hour. It just SEEMS like it would be easier to switch to premade paper templates and enter them in later.
If you ever have to do it, please let us know how it goes.
