Disaster Recovery Overview

The Stratus everRun Disaster Recovery (DR) feature enables you to protect VMs running on everRun systems.

DR protection involves taking snapshots of VMs running on a primary system and replicating the VMs and their snapshots to a DR system located at a separate DR site. The VMs running on the first system are called primary VMs. The backup VMs on the system at the DR site are called DR VMs.

You can control how often snapshots are taken and the number of snapshots to be retained, up to the allowed maximum. Should a failure occur, DR protection provides for the recovery of VMs with minimal data loss. For maintenance and other planned outages, it provides the ability to move a running VM to a different system with no data loss.
