One-to-many
Description
One source server sends data to multiple target servers. The target servers may or may not be
accessible by one another.
Applications
This configuration provides offsite disaster recovery, redundant backups, and data distribution. For
example, this configuration can replicate all data to a local target server and separately replicate a
subset of the mission-critical data to an offsite disaster recovery server.
Considerations
Updates are transmitted multiple times across the network. If one of the target servers is on a WAN,
the source server is burdened with WAN communications.
