Remote Replication Concepts
The following is a list of the common replication terms.
replication source - An appliance that sends replication updates to one or more target
■
appliances, periodically, continuously, or on demand. Individual appliances can act as both a
source and a target, but are only one of these in the context of a particular replication action.
replication target - An appliance that will receive and store data replicated from one or
■
more source appliances. appliance. This term also refers to a configuration object on the
appliance that enables it to replicate to another appliance.
replication peer - An appliance that has been configured as a replication source or target.
■
replication action - Describes the data to be replicated, the replication schedule, and the
■
data transfer properties such as enabling or disabling encryption of the network link.
replication group - The set of datasets (exactly one project and some number of shares)
■
which are replicated as a unit. See
replica - Replicated data contained in the replication package on the target appliance.
■
replication package - Exists on the target and is associated with a replication action. It is a
■
special object that contains the replica. The loss of either object will require creating a new
action/package pair and a full replication update. The link between an action and its package
can be severed, preventing future updates but enabling write access to the replica.
clone - A replicated package can be cloned into a mutable project. This can be managed like
■
any other project on the system.
full sync (or full update) - A replication operation that sends the entire contents of a project
■
and some of its shares. The initial sync of a project and/or share will be a full sync.
incremental update - A replication operation that sends only the differences in a project
■
and its shares since the previous update (whether that one was full or incremental).
reverse replication - A replication relationship that exchanges the source and target roles.
■
Following a disaster recovery, roles can be reversed again.
