DRE procedures

Integrating DRE with a cloud system allows you to perform multiple procedures, like creating a DR service, updating it, and using it when a disaster occurs.

Overview

The following diagram shows the relations between the main components of a disaster recovery setup. It illustrates the case where the CMP governs all zones:

Note that the diagram shows only the essential disaster recovery operations. The actual implementation contains more actions.

Protection models

The DR Engine supports multiple protection models:

  • Active-passive VMs in a primary site are protected in a recovery site, used solely for recovering workloads in a disaster scenario.

  • Active-active Two zones run VMs, and both zones send recovery points to the remote zone, each acting as both a primary and a recovery zone for the other.

  • Many-to-one Multiple primary zones run workloads that are protected in a single recovery zone used solely for recovering workloads in a disaster scenario.

  • Multi-site mesh Multiple zones run workloads and protect each other, acting as both primary and recovery sites.

Disaster recovery procedures

Using the REST API of the DRE allows you to perform the following procedures:
