Replication processing involves the interaction between
replication rules, states, and modes. Data deduplication and the updating
of client node attributes are also factors in node replication processing.
Replication rules
Replication rules control what data is replicated and the
order in which it is replicated.
Replication state
Replication state indicates whether replication
is enabled or disabled. When you disable replication, replication
does not occur until you enable it.
Replication mode
Replication mode is part
of a client node definition and indicates whether a client node is
set up to send or receive replicated data. The replication mode can
also indicate whether the data that belongs to a client node is to
be synchronized the first time that replication occurs. Data synchronization
applies only to client nodes whose data was exported from the source
replication server and imported on the target replication server.
Replication of deduplicated data
Data deduplication is a method for eliminating
redundant data that is stored in sequential-access disk (FILE) primary
storage pools, copy storage pools, and active-data storage pools.
Before the data is replicated, the source replication server determines
whether storage pools are set up for data deduplication.
