Correct.

There is no way to promote a subscriber to a publisher  
unfortunately.   If you never took a BARS backup of the publisher  
then you are looking at reconfiguring everything.

You can BAT out your phones and users at least but everything else  
will have to be configured by hand.   The good news is that you still  
have the subscriber to use as a template for the config.

That’s just it we never ran BARs on the Publisher so I have no good  
back up of the publisher. I wanted to know if I could run it on the  
subscriber and uses the subscriber DB to recover the Publisher Database.

The database on the publisher should be the exact same as the last  
state of the publisher.  What it sounds like was your BARS backups  
have been failing L


TAC may be able to assist, but not likely.  It is extremely rare for  
TAC to spend the time reworking subscribers, usually only in cases  
where the issue was caused by BARS itself.


How many users and how far back would you have to go to get a good  
bars backup?

Issue: We have a Publisher and Single Subscriber Cluster. The  
Publisher has crashed and will require a new install of OS, patches  
and CCM. I would like to recover it to the Database still running on  
the subscriber. Can I


1.)     Promote the Subscriber to a Publisher and install the old  
publisher as a subscriber?

2.)     Run BARS on the Subscriber and then recover the Publisher as  
a Publisher but use the BARS to restore the database?

3.)     Change the replication process to replicate one way from the  
subscriber to the publisher

4.)     Something Else


Thanks in Advance!
