Disaster Recovery with Remote Replication

A two-system disaster recovery site consists of a source appliance at a production site and a replication target located at a recovery site in a geographically different location. In the event of a catastrophic production site failure, the administrator redirects client operations to the recovery site by reversing replication on the replication target, thus ensuring continuous operation. After the production site is restored to normal operation, the administrator updates the production site by reversing replication at the recovery site. To restore the original source-target relationship, replication is then reversed again.

Note:

Replication reversal is not supported to a filesystem with mandatory file retention. For information about the file retention feature, see File Retention Management.

To set up remote replication for disaster recovery, use these tasks:

  • Setting Up a Target Appliance at a Recovery Site - BUI, CLI

  • Switching Operations to the Recovery Site - BUI, CLI

  • Updating the Production Site - BUI, CLI

  • Reversing Replication Back to the Production Site - BUI, CLI
