Written by: Murray White - Solution Architect at Vision SolutionsThe following video demonstrates how to protect a Windows Server 2008 R2 (Server Core) to a standby Server, using the “Full Server Failover” protection option of Double-Take Availability 6.0.Though this demo is conducted on a Server Core OS, the same Double-Take workflow applies for protecting servers running non-core versions of Windows Server (2008, 2008-R2 or 2003, 2003-R2). 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 demonstration specifically details:1) Configuring Double-Take Availability with a Full Server Protection job2) Synchronize data from source server to target server3) Monitor the Double-Take job4) Fail-over from source server to target server5) Invoke Reverse Protection while failed over6) 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.
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.
