Replication configuration/ Replica server
What actually is Replica server ? this is same as actual production server that has application and copy to another physical servers?
then what is replica vaults? how the connection is made between Main site and the replica server?
I am just confused between Replica server and replica vaults. can you please explain me in detail.
Or do you have any document that has the details of replication configuration and precisely explain the Master site and replica site?
