Arcserve Replication is a data protection solution that uses asynchronous real-time replication to provide disaster recovery capabilities. This host-based software provides continuous data replication that transfers changes to application data as they occur to a standby replica server located locally or over the Wide Area Network (WAN). Continuous data replication ensures that the most recent data is always available for restoring purposes. Continuous data protection is based on Data Rewind technology for recovery from data corrupted by viruses, user error, or application error.
You can also improve your data protection capabilities by adding application monitoring and fully automated failover and failback. These capabilities are provided by Arcserve High Availability (HA), which is a high-availability solution for true continuous application availability.
Arcserve High Availability offers a superset of the capabilities of Arcserve Replication. In particular, Arcserve High Availability adds the capability for push-button or automatic failover of clients from the production Master server to a secondary Replica server, without any need to reconfigure clients, as well as the ability to automatically monitor the status of the production server and the applications running on it. After the Master server is restored to its original state, Arcserve High Availability lets an IT administrator reinstate the Master server with the push of a button, automatically failing back from the Replica server with no loss of data or application availability.
