The main factors to consider when planning replica synchronization
are method, scheduling, and pattern.
Several
methods for transporting update and replica-creation packets are available.
The method you choose depends on how your sites are connected, how quickly
you must transfer packets, and the importance of security.
Synchronization schedule
The synchronization schedule for a family defines when replicas
in the family send and receive updates. The schedule is affected by many factors,
including the rate of development at different sites, the connections among
sites, and whether you use MultiSite as
a backup strategy.
Synchronization pattern
The synchronization pattern for a family defines which replicas
exchange update packets and the direction of exchange.
