Failover and Failback: Recovering From Disaster

With PHD Virtual Backup configured to backup and replicate your virtual machines, you are well protected in the event of a DR scenario. If your primary site becomes unavailable, you have multiple options available for recovering your business critical data.

Figure B - 9. An unavailable primary site with VMs powered on at the DR location.

PHD Virtual Backup's VM Replication feature allows you to failover replicated VMs. What this means is, when your primary location is unavailable, you can power on the replica VMs at your DR site to continue your day to day operations. When your primary site is recovered, or when you're ready to populate a new production site, you can use PHD Virtual Backup to fail back to your new location, by either seeding the servers at the new site, or restoring backups of the failed over VMs into your production environment. For more information on seeding, see Seeding a DR Site.

Figure B - 10. Failing back to a primary site from a DR location

When the primary location has been completely recovered (failover and failback has occurred), you can begin replicating to your DR site, once again.

For more information on configuring replication and VM failover, see Disaster Recovery - Replication.
