Given your scenario - if you did a restore then you would get an error message 
of something like

NSMMReplicationPlugin - agmt="cn=master-t01-to-master-t02" 
(ldap-master-t02:389): Replica has a different generation ID than the local 
data.

Yes, I just did this.  Then you would want to conduct an online initialization 
to bring the replica back into sync.  Given this, all you need to do is monitor 
that replication is working.  Under normal operations you won't have a problem. 
  If you start doing exceptional things like mucking directly with the DB file, 
then this is how you might get into the trouble you describe and the solution 
is to re-init the replica.

i hope this helps.
