The first step in creating the failover solution is to set up the backup machine. This is the computer that will take over if the primary computer fails.

To set up the backup machine:

• Create a directory named IguanaData (for example, C:\IguanaData). In this directory, create subdirectories named Logs and Config.

	These sections will assume that the directory you have just created is C:\IguanaData. If you have created a directory elsewhere, replace C:\IguanaData with the path you have chosen.

• Use the instructions in Installing Iguana On Windows Using The Automatic Installer to install Iguana on the backup machine. When asked for a log directory, type C:\IguanaData\Logs. All other installation settings can be left as their default values.
• When the Iguana setup wizard is completed, ensure that the Open the iNTERFACEWARE Iguana Dashboard check box is selected:

• The copy of Iguana that you have just installed will appear. Do not log in yet.
• Stop the Iguana service using the instructions provided in Starting and Stopping the Iguana Service.
• Using Windows Explorer, move to the directory in which you have just installed Iguana. (Typically, this is C:\Program Files\iNTERFACEWARE\Iguana.)
• Edit iguana_service.hdf to set the Iguana configuration directory to C:\IguanaData\Config. For details on how to do this, see Specifying the Configuration File Directory.
• Move the Iguana configuration file, IguanaConfiguration.xml, from the directory in which Iguana is installed to the C:\IguanaData\Config directory.
• Modify the Iguana service so that it is started manually rather than automatically. To do this, click Start > Settings > Control Panel > Administrative Tools > Services. When the Services window appears, right-click iNTERFACEWARE Iguana and select Properties. In the window that appears, from the Startup type list box, select Manual.
• Start the Iguana service using the instructions provided in Starting and Stopping the Iguana Service.
• In your web browser, log into Iguana using the default userid and password. Use the Iguana ID shown on the installation screen to obtain an Iguana license for this server. (See Registering and Licensing Iguana Version 4.0 Or Later for instructions on how to do this.)
• Log out of Iguana and stop the Iguana service again.
• Using Windows Explorer, move to the C:\IguanaData\Logs directory. Delete all files in this directory.
• Move to the C:\IguanaData\Config directory. Delete all files in this directory except the Iguana license file (which is named IguanaLicense).
• Install DeltaCopy, following the instructions provided. (You can use the default settings when installing.) Select the Launch the program check box:

• The DeltaCopy server window appears, indicating that the DeltaCopy server is not registered yet:

• Click Register Windows Service to register the service. A password window appears:

• In the Account Name field, type the Windows user name that you want to use to run DeltaCopy (for example, Administrator).
• In the Password field, type the password for this user name. Click Ok. The DeltaCopy Server Console window appears, and a popup box indicates that the service has been created:

• Click the Virtual Directories tab. In the Existing Directories panel, select Backup:

• Right-click and select Delete Directory.
• In the Existing Directories panel, double-click <Add New Directory>. In the popup window that appears, type IguanaData:

• In the Existing Directories panel, select IguanaData. Click the Browse button located next to the Path field. In the browsing window that appears, locate the C:\IguanaData directory and select it.

• Click the Server Status tab, and click Start Server. The stoplight should change from red to yellow and then to green:

You have now successfully installed Iguana and DeltaCopy on the backup computer. The next step is to install Iguana and DeltaCopy on the primary machine.

	When you start the DeltaCopy server, you may see the following error: ` If this error occurs, click Start > Settings > Control Panel > Administrative Tools > Services to open the Services window. Right-click DeltaCopy Server and select Properties. When the Properties window appears, click the Log On tab, and select the Local system account radio button: Click OK. Return to the DeltaCopy Server window and click Start Server again. The server should start successfully.
