- Close any open applications.
-
Start the installation program using the appropriate instructions, depending on your media source.
- Physical media—If auto-run is enabled, the installation program will start automatically. To manually start the program, select Start, Run and specify <drive>:\autorun.exe.
- Web download—Launch the .exe file that you downloaded from the web.
If you are installing on Server Core, copy the physical media files or web download file to the Server Core machine using a UNC share, and then launch the installation program from the Server Core machine. The installation UI will display on the Server Core machine.
- When the installation program begins, the Autorun appears allowing you to install software and view documentation and online resources. To install Double-Take Availability, select the Install Double-Take Availability link.
- Depending on your version of Windows and the components you have installed, you may see an initial screen indicating that you need to install or enable Microsoft .NET Framework. If you do not see this screen, your server already has the appropriate version of Microsoft .NET. You must install or enable Microsoft .NET before installing Double-Take. Select Yes to install or enable Microsoft .NET and click Continue.
- If you are upgrading from a previous version of Double-Take RecoverNow, and you have any Double-Take archived or deduplicated files, you will be prompted to recall and restore those files manually. Double-Take RecoverNow will automatically be uninstalled, however you must recall and restore those files first.
- You will be given the opportunity to check for a more recent version of the software.
- If you do not want to check for a later version, select No and click Next.
- If you want to check for a later version, select Yes and click Next. The installation program will establish an Internet connection from your server to the Vision Solutions web site.
- If later versions are found, they will be listed. Highlight the version you want and either download that version and install it automatically or download that version and exit the installation. (If you exit the installation, you can run the updated installation later directly from the location where you saved it.)
- If no later versions are found, continue with the current installation.
- If an Internet connection cannot be established, continue with the current installation or install a previously downloaded version.
- If you are upgrading, review the upgrade note.
- Any jobs that were created in legacy Double-Take consoles, including Replication Console, Full Server Failover Manager, Application Manager, Double-Take Move Console, or DTCL, will no longer function once the upgrade is complete.
- Jobs that were created in the version 5.2 Double-Take Console must first be upgraded to version 5.3, and then they can be upgraded to version 6.0. You can also delete any jobs created in the version 5.2 Double-Take Console, upgrade directly to version 6.0, and then re-create the jobs.
- Any jobs created in the version 5.3 Double-Take Console will be upgraded and will continue to function normally.
- If you are protecting Hyper-V virtual machines at the host-level using a cluster configuration, you cannot upgrade. You must delete the existing job, upgrade all of your nodes, and then re-create the job.
- Click Next to continue.
- If you are upgrading from Double-Take RecoverNow with TimeData, select if you want to uninstall the TimeData components. You can also remove Ontrack PowerControls if you have that installed. The uninstall may be time consuming while it removes the associated SQL instance and deletes the continuous data protection storage bins. Additionally, the TimeData uninstall may require a reboot. If you choose not to uninstall TimeData or Ontrack PowerControls, Double-Take RecoverNow will still be uninstalled, and these programs will no longer function after the upgrade. If you do not remove the products, you will have to manually remove them. See the support site for complete instructions on the manual removal process.
- Review and accept the Vision Solutions license agreement to continue with the installation program. Click Next to continue.
- Review the activation notice. Most Double-Take version 6.0 and later licenses require activation after installation for full product functionality. Failure to activate licenses that require it will cause your Double-Take jobs to fail. See License management and activation for more details.
- Click OK to continue.
-
Select the type of installation you would like to perform on this machine.
- Client and Server Components—This option installs both the client and server components. The server components are required for systems that will function as a source or target. The server requires an activation code for the service to run. The client does not require an activation code, but it is required to administer this and other Double-Take servers throughout the organization.
- Client Components Only—This option installs only the client components. The client components do not require an activation code, but are required to administer Double-Take servers throughout the organization.
- Server Components Only—This option installs only the server components. The server components are required for systems that will function as a source or target. The server requires an activation code for the service to run.
If you are installing on Server Core, you will only be able to select the Server Components Only installation. You will not be able to run the client components from the Server Core machine. The client will have to be run from another machine.
- If desired, specify where the Double-Take files will be installed by clicking Change, specifying a location, and then clicking OK.
-
Click Next to continue.
If you selected a client only installation, continue with step 15.
-
You will be prompted to enter your activation code information. Your Activation Code is a 24-character, alpha-numeric activation code which applies the appropriate license to your installation. Enter your code and click Add.
If you are installing Double-Take for the first time, you will not be required to add an activation code, however the product will not work without one. If you are upgrading an existing version, you must have an activation code to continue the installation.
- Click Next to continue.
- Double-Take uses system memory for Double-Take processing. The maximum amount is dependent on the server hardware and operating system. Specify the maximum amount of system memory that Double-Take can use and click Next to continue.
- When the allocated Double-Take system memory is exhausted, Double-Take will queue to disk. If you want to disable disk queuing, deselect Enable disk queue. Ideally, you should use disk queuing. Specify the Queue folder, which is the location of the disk queue. By default, the size of the disk queue is set to Unlimited disk queue, which will allow the queue usage to automatically expand whenever the available disk space expands. If desired, you can select Limit disk space for queue and specify a fixed disk space amount. You can also specify the Minimum free disk space, which is the minimum amount of disk space in the specified Queue folder that must be available at all times. This amount should be less than the amount of physical disk space minus the disk size specified for Limit disk space for queue. (See Double-Take queue for additional guidelines on selecting appropriate queue settings.) Click Next to continue.
- The Double-Take security information screen appears next. Review this information and click Next to continue with the installation.
- If you are satisfied with the selections you have made and are ready to begin copying the Double-Take files, click Install.
- During the installation, you may be prompted to add an exception to the Windows Firewall for Double-Take. Click OK to add the port exceptions. If you Cancel the port modification, you will have to manually modify your firewall settings for Double-Take processing. See Core Double-Take requirements.
- After the files have completed copying, click Finish to exit the installation program.
