A feature of VVR that allows replay of the SRL from an earlier point than the current position. A checkpoint delineates with starting and ending points the section of the SRL to be replayed later.

The checkpoint is a Replicator Log position recorded by the Primary Replicated Volume Group (RVG). This can be specific to a Secondary and can be initiated either by the Primary or Secondary. The checkpoint can also be applicable to both the Primary and Secondary nodes. The checkpoints are used to restore the Secondary node(s) from an earlier known state using the checkpoint in the Replicator Log. A checkpoint is available as long as the checkstart mark exists on the Replicator Log.
