Double-Take Server Recovery Option
Double-Take, when combined with the Double-Take Server Recovery Option (SRO), provides a single solution to continuously protect and recover an entire server. Protection is provided by the industry-proven real-time replication of Double-Take while recovery is performed by the Server Recovery Option. The Recovery Manager, provided as part of the Double-Take Server Recovery Option, presents the task of server recovery as a series of easy-to-understand steps. Because Double-Take replication protects the entire production server –- its operating system, applications and data, restoring the server encompasses as few steps as possible and provides a significantly better recovery time than existing solutions such as tape backup.
Built on patented Double-Take technology
The Double-Take Server Recovery Option is used in conjunction with Double-Take and its replication technology, the world's most relied-upon solution for accessible and affordable data protection solutions for disaster recovery and centralized backup. Double-Take utilizes patented replication and failover technology that continuously captures byte-level changes as they happen and replicates those changes to one or more secondary servers at any location - locally or at a recovery site miles away.
Easy implementation and management
The Double-Take SRO features additions to the Double-Take Management Console that provide an easy-to-follow wizard for creating a connection that protects the entire server. Once installed, Double-Take performs an initial mirror of the server, including data, applications and operating system. When the mirror is complete, Double-Take begins replicating changes made, at the byte level, to the operating system, data and applications. This replication of system state ensures that the entire server can be recovered in the event of a disaster or data loss. In some cases, not every volume on a server needs protected. The Double-Take Server Recovery Option provides the option to exclude one or more data volumes at either protection or recovery time based on an organization's specific requirements.
Fast and easy recovery with Recovery Manager
The Recovery Manager application, included with the Double-Take Server Recovery Option, allows you to quickly and easily configure and perform recovery, including validation steps that ensure recovery goes as planned. When a system volume or entire server fails, recovery of both system state and data can be performed from the Recovery Manager, reducing the number of steps needed to recover a server to its original state. The Recovery Manager also eliminates many of the steps required by traditional backup and restore solutions by requiring only a standard Windows OS on the new system.
Broad Application Support
The Double-Take Server Recovery Option protects the entire server so there is no need for specialized application support as is the case with tape backup solutions. The Double-Take Server Recovery Option supports most business-critical applications and replicates between any configuration of physical and virtual systems. The Double-Take SRO also integrates with Microsoft® Volume Shadow Copy Service to allow you to schedule and recover from up to 512 point-in-time copies of protected data. And, with the exception of a matching operating system, the recovery server does not have to be an exact match for the server you are recovering.
Double-Take Server Recovery Option in a Branch Office Scenario
Let's look at the initial example scenario that was provided, instead utilizing the real-time, whole-server protection and streamlined recovery of Double-Take and the Double-Server Recovery Option. When the branch server being protected fails, the administrator in the central office uses the Recovery Manager to choose the appropriate recovery server. This recovery server resides on the network at the branch office, but only requires a baseline Windows operating system to be installed - no additional provisioning of software is required. The Recovery Manager validates the compatibility of the recovery server, then quickly restores applications and data that have been protected, in real-time, by Double-Take. Once the restoration process has finished, business can resume at the branch office with minimal downtime and lost data.
Summary
Recovering your production server from backup using traditional recovery solutions can be a cumbersome and stressful process. Complex restoration software and the inability of solutions like tape backup to protect data in real-time don't improve the situation. Double-Take and the Double-Take Server Recovery Option provide a better alternative - real-time data protection with a streamlined recovery process that reduces the time and effort involved with server recovery.
