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.
