Many-to-one
Description Many source servers are protected by one target server.
Applications
This configuration is appropriate for offsite disaster recovery. This is
also an excellent choice for providing centralized tape backup
because it spreads the cost of one target server among many source
servers.
Considerations
●
The target server must be carefully managed. It must have
enough disk space and RAM to support replication from all of
the source systems. The target must be able to accommodate
traffic from all of the servers simultaneously.
●
If using failover, scripts must be coordinated to ensure that, in
the event that the target server stands in for a failed server,
applications will not conflict.
●
You must pause the target when backing up database files on
the target.
