Recovering to a Backup Site

In the event of a production site failure, you manually activate the backup site.

To recover to the backup site, issue the dr-recover command at the backup site.

Recovering from a disaster only requires one appliance be available at the backup site. The full quad is required to setup the DR feature, but not to recover from a DR event. For example if one of the appliances at the backup site is down for repair, you can still recover to the available appliance.

  • If both Backup-A and Backup-B are available, OR if only Backup-A is available, then issue dr-recover on Backup-A.
  • If only Backup-B is available, issue dr-recover from Backup-B.

dr-recover erases all prior EMS server data from the backup site and overwrites it with the data from the production site snapshots.
