Peer DRS Usage Scenarios

Below are some common usage scenarios for Peer DRS along with network diagrams depicting the scenarios and which replication modules support the scenario:

1) One-to-One Standby Replication: Replicate one or more primary databases to a standby server on different servers mirroring the original configuration across a LAN or WAN.  (Probably the most common)

Supported Replication Modules:  MS SQL Server, MS Exchange Server (Target storage group and database names must match the primary)

2) Many-to-One Standby Replication: Replicate multiple primary databases residing on different primary servers or database instances to a single standby server across a LAN or WAN.

Supported Replication Modules:  MS SQL Server, MS Exchange Server (Target storage group and database names must match the primary)

3) One-to-Many Standby Replication: Replicate one or more primary databases residing on a single server to multiple standby servers on different servers tn the same LAN or across a WAN.

Supported Replication Modules:  MS SQL Server

4) One-to-One File Copy Only Replication: Perform full and incremental backups and store offsite to one or more locations for disaster recovery without needing to restore to a  stand-by. In addition, these remote locations can be used as backup archive libraries.  This configuration can also be used to support On-Demand target failover in instances where you do not want to install database server software on the target server (to avoid additional vendor licensing fees) until failover/target recovery is performed.

Supported Replication Modules:  MS SQL Server, MS Exchange Server

5) One-to-One Multiple Location Replication: Replicate a primary database to multiple standby servers on different machines across different networks to further reduce the chances of downtime. In addition, each standby server can be used for a different purpose--one server can be used for reporting, another one for providing high availability and another one to store secure copies of database backup archives on a remote server.

Supported Replication Modules:  MS SQL Server, MS Exchange Server (Target storage group and database names must match the primary and target databases cannot be mounted)

6) Clone database to Same Database Server: Backs up and copies a single database to the same server instance under a different database name.  This can be used to make a quick clone of a database for testing purposes.

Supported Replication Modules:  MS SQL Server
