Overview

Disaster recovery engine is a piece of software created and used within the Infrascale Disaster Recovery to back up target machines (clients) running Windows. It is installed on a client along with the DR backup agent.

Engine options

DR engine is set for each client individually as part of the DR image backup settings. To view the available DR engine options, go to the CFA Management Console > Clients > Edit, select the desired client, and then click the Engine drop-down list in the Disaster Recovery Image group.

Option Description
Auto Set by default. Recommended. If selected, the system automatically chooses a DR engine to use for client backups
Standard If selected, the system uses the standard DR engine for client backups
Legacy Not recommended unless instructed by Infrascale Support. See details

Standard engine

Standard is the current implementation of the Infrascale DR engine used by default starting from Infrascale Disaster Recovery 8.0.

It is designed and used to create application-consistent backups of the entire physical machines, and of the VSS-aware applications, for example Microsoft Exchange Server, Microsoft SQL Server, SharePoint Server, and others.

It fully integrates with Microsoft VSS, and uses available VSS writers for the respective applications to provide consistent, reliable, and fast backup results.

Standard DR engine supports the following Windows versions:

  • Windows 7 SP1 or later
  • Windows Server 2008 R2 SP1 or later
