Refer to the following information on how Volume Replicator helps with disaster recovery in any application environment:

• Write Order Fidelity:

  Volume Replicator guarantees that changes made to data on the primary host are made in the same sequence on the secondary host. This ensures that the data remains in a consistent state in the event of a disaster.

• Synchronous Replication:

  Volume Replicator guarantees that changes committed on the primary host are committed on the secondary host first. This ensures that the data on the secondary host matches the data on the primary host and minimizes data loss in the event of a disaster.

• Asynchronous Replication:

  Volume Replicator reflects the changes to the application immediately on the primary, and changes are then reflected on the secondary as soon as possible. Until the data is sent to the secondary, it is stored on the Replicator Log.

• RVG Snapshot:

  This provides the ability within Volume Replicator to take a point-in-time snapshot of a volume. This allows verification of the consistency of the data on the secondary host without impacting replication between the primary and secondary hosts.

• Heterogeneous Storage Support:

  Volume Replicator provides a replication technology that works with heterogeneous storage hardware. Volume Replicator allows replication to occur between similar or dissimilar storage arrays from a vendor or between different storage arrays from different vendors. This allows for maximum use of existing hardware and provides flexibility when adding new hardware.
