Disaster Recovery

Important!   Procedures in this chapter are for Unitrends systems running version 7.0 and higher. If replicating, both the source and target systems must be running 7.0 or higher. For systems running older versions, see the Legacy Disaster Recovery chapter. If restoring a Unitrends Backup appliance that was originally deployed on Unitrends, version 8.1 or higher, you can recover using the storage from the failed Unitrends Backup. See the "Setting up a Unitrends Backup appliance with existing backup data" procedure in one of these guides: Deployment Guide for Unitrends Backup on VMware or Deployment Guide for Unitrends Backup on Hyper-V.

Protecting an organization’s data and IT infrastructure has never been more important. This document describes the steps the Unitrends customer needs to take when planning and implementing a disaster recovery (DR) strategy. This strategy includes decisions that are best made long before a failure occurs.

An effective disaster recovery strategy consists of four aspects:

• The decision to archive or replicate
• Preparation
• Restoring to a physical or virtual system
• Restoring backup data to clients

See the following topics for details:

• Archive or replicate
• Preparation
• Restoring the system
• Scenario 1: Restoring a backup system
• Scenario 2: Recovering from a corrupt backup device
• Scenario 3: Recovering from a corrupt RAID
• Scenario 4: Recovering a corrupt internal drive
• Post-recovery considerations
• Restoring backup data to the clients
