Yes, so long as you used the same version of FASTBACK, the save/restore
will go flawlessly (or so it always has been for me and everyone I know!).

        3a. Format the partition using the new DOS (I always do a
            "FORMAT/S" since this seems more reliable (gut feel) than
            a format followed by a sys.

       4. SYS only if you did a FORMAT without the "/S" above.

I do not know, I have always just reinstalled FASTBACK -- a better
alternative is just copy the \fastback directory to a floppy without
using BACKUP/RESTORE (the only thing that is different from a reinstall
is the presence of the backup directory file, I think).

You're welcome (especially if I got it right!)
