There are a number of things that happen when you perform a non
authoritative restore.
FRS database, chkpoint, and log files are purged and recreated.
The server determines which replica sets it should be a member of and
rejoins them as if it is a new member.
It creates a new database, chkpoint, and logs.
It moves all the data in the replica set folders into a folder called
NTFRS_PREEXISTING.
It then proceeds to replicate across the wire any files in the replica set
that are new or have been modified. The rest of the (matching) data in the
set is moved from the pre-existing back into the replica set folder
structure.
Any data on this member that did not match the data on an upstream neighbor
(MD5 checksum comparison) will remain in the pre-existing folder until you
(the admin) reviews it and determines it is valid data or not.
Your old databse (if backed up) is completely useless at this point.
I would be surprised if the replica would work (correctly) if you attempted
to revert to the old database after performing the restore
Never tried it though.......
Sounds like a good lab excercise.
Cheers!
