Written by: Murray White - Regional Lead of Sales Engineering at Vision SolutionsThe 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, P2PThe 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 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.
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.
