Double-Take Requirements for SBS

In addition to the Core Double-Take requirements (see Double-Take 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. 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. To protect a Small Business Server source, your target server can be Windows Server 2003/8 Standard edition (OS family of 2003 or 2008 based on whether protecting a SBS 2003 or SBS 2008/2011 server).
  • 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.
  • 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—This operating system is only supported in a Server Core to Server Core configuration.
  • 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.
  • Double-Take licensing—If you are protecting a full server in a physical source to virtual target configuration, you will be unable to reverse if your virtual target has a Double-Take Availability Virtual Guest Edition license. If you want to reverse, you will need to have one of the other (non-virtual) Double-Take Availability licenses.
  • 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. You can install this version from the Double-Take CD, 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 installing on Server Core 2008 R2, .NET 3.5.1 functionality is included with the operating system but is disabled by default. You will need to enable it prior to installing Double-Take. See your Server Core documentation for the specific commands to enable the .NET functionality.
  • Supported configurations—The following table identifies the supported configurations for a full server job.

Full server protection of a cluster is not a default supported configuration, but it is possible with assistance from Professional Services. If you want to use a full server job in a cluster environment, contact Sales or Professional Services. Because this is an advanced configuration, you will be referred to Professional Services for further assistance.

Double-Take Foundation Edition Licensing

Windows 2003 and 2003 R2 operating systems
  • Storage Server Edition
  • Small Business Server

Windows 2008 and 2008 R2 operating systems
  • Storage Server Edition i386 and x64
  • Small Business Server Standard and Premium x64
  • Foundation Server with SAK
  • Essential Business Server x64

Virtual server protection: There is no virtual server (guest-level or host-level) protection with the Foundation Edition.
Notes: You can install the Foundation Edition on a server running other server Windows operating systems, so you do not have to pay extra for an upgraded Double-Take license. When the Foundation Edition is installed on a server running these other server Windows operating systems, the following limitations will apply.

  • The server will function in a target role only.
  • The target-only server can only protect a source that is running the Double-Take Foundation Edition and one of the operating system editions listed for the Foundation Edition.
  • Full server protection is the only supported method of failover.
