    After you have finished restore you will start replication using checkpoint using:

    vradmin -g diskgroup -c checkpoint_name startrep rvg_name

    This will replay the SRL from checkstart and if you check status of replication it will be inconsistent as during this phase, VVR is copying the blocks that were written during the backup, some of which will already be there (as it depends on whether the block was written before of after the block was written to tape).  When the SRL gets to check_end, replication will be consistent and VVR will then continure to replay SRL until it is up-to-date and will then still continue for ongoing writes.
