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.
●
You must pause the target when backing up database files on
the target.
