Many-to-one
Description Many source servers are protected by one target server.
Application 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.
