This article will detail the appropriate points in configuration where the use of Checkpoints within the Veritas Volume Replicator (VVR) software is necessary.
VVR Checkpoints are user-defined markers on the Primary Replciator Log. There are 2 types of checkpoints
- RVG Checkpoint
- RLINK (Secondary) Checkpoint
The RVG checkpoint has a start (Checkstart) and an end (Checkend) and can be used for initial synchronisation.
The process requires the configuration of a CheckStart process. Once this is complete, a block level backup of the Primary Data is necessary, before performing a CheckEnd.
After this is complete, the data must be restored to the Secondary site before starting / resuming replication using the CheckPoint configured at the beginning of the process.
The RLINK (Secondary) CheckPoint is used to restore Secondary volumes in case of failure.
