Full Server Protection using Double-Take Availability v7

Full Server Protection using Double-Take Availability v7


The following video demonstrates how to protect a Windows Server 2012 to a standby Server, using the "Full Server Failover" protection option of Double-Take Availability 7.0. The Source server in this demonstration is running SQL Server 2012.

Data and Applications running on protected servers (such as SQL Server, MS-Exchange, Oracle) are replicated and protected as part of the full server protection job and are fully available for use on the target server following fail-over... just as they were on the source server prior to fail-over.

The Source and Target servers can be physical or virtual... and the protection can be from one to another.
Example: P2V, V2V (including cross-hypervisor), V2P, P2P

The demonstration specifically details:
  • Configuring Double-Take Availability with a Full Server Protection job
  • Synchronize data from source server to target server
  • Monitor the Double-Take job
  • Fail-over from source server to target server
  • Invoke Reverse Protection while failed over
  • Fail-over to original source server

Double-Take Full Server Protection Requirements

In addition to the Core Double-Take requirements (see User Guide), use these requirements for full server protection.
  • Operating system—The source and target servers can be any operating system listed in the Core Double-Take requirements section of the User Guide. However, keep in mind that a target server may meet these requirements but may not be suitable to stand-in for a source in the event of a source failure. See Target compatibility section of the User Guide for additional information regarding an appropriate target server for your particular source.
  • Operating system language—Your servers must be running the same Windows localized version. For example, if your source is running an English language version of Windows, your target must also be running an English language version of Windows. If your source is running a Japanese language version of Windows, your target must also be running a Japanese language version of Windows. This applies to all localized languages.
  • Source and target preparation—Uninstall any applications or operating system features that are not needed from both your source and target. For example, unused language packs will slow down failover since there are thousands of extra files that need to be examined. Ideally, your target should be as clean and simple a configuration as possible.
  • Source storage—If you will be enabling reverse protection, the source must have enough space to store, process, and apply the target's system state date. See the disk space requirements in Target compatibility section of the User Guide for details on the space requirements for various operating systems.
  • Storage Server Edition—If you are using Windows Storage Server Edition, you will need to check with your NAS vendor to verify if there are technical or license restrictions on failing over an image of a server to different hardware.
  • Microsoft Server Core 2008 R2 or 2012—This operating system is only supported in a Server Core to Server Core configuration. Additionally, DNS updates are not supported for Server Core servers.
  • Hyper-V servers—Full server protection of a Hyper-V server is not supported.
  • Network adapters—NIC teaming is not supported for full server protection.
  • NAT support—Full server jobs can support NAT environments only when reverse protection is disabled. Additionally, your NAT environment must be an IP-forwarding configuration with one to one port mappings. Port-forwarding is not supported. Also, only IPv4 is supported for NAT environments. Make sure you have added your servers to the Double-Take Console using the correct IP address. Review the NAT Configuration table in the Adding Servers section of the User Guide before you start the job creation process.
  • Microsoft .NET Framework—Microsoft .NET Framework version 3.5 Service Pack 1 is required on the source and target. This version is not included in the .NET version 4.0 release. Therefore, even if you have .NET version 4.0 installed, you will also need version 3.5.1. If you are using Windows 2008 or earlier, you can install this version from the Double-Take DVD, via a web connection during the Double-Take installation, or from a copy you have obtained manually from the Microsoft web site.If you are using Windows 2008 R2 or later, you can enable it through Windows features.
  • Snapshots—You can take and failover to Double-Take snapshots using a full server job. See Core Double-Take requirements in the User Guide for the specific snapshot requirements.
