The File Replication Rules page displays all existing file replication rules and allows creation of new rules. Replication rules comprise optional configuration parameters that allow replications to be tuned to enable/disable specific functions or to optimize performance.
Replication Rules control values like the number of read-ahead processes, minimum file size used in block replication, when snapshots are deleted and whether replications will include migrated files. The server’s default values should be optimal in most cases; however, these values can be changed to customize replication performance characteristics based on the data set.
