You can use DeltaCopy, an open-source incremental backup program, to create a solution consisting of two Windows computers running Iguana, one of which serves as the backup for the other. If the first computer fails, the second computer can immediately take over.

To implement this Iguana failover solution, you will need the following:

• Two computers running Windows, with the operating system being Windows 2000 or higher;
• A copy of the DeltaCopy installation file on each computer (this can be obtained here);
• A copy of the Iguana installation file on each computer (version 4.0 or later);
• IP addresses or DNS lookup entries for each of the computers.

To create the Iguana failover setup, you will need to:

• Set up the backup machine to run Iguana and the DeltaCopy server;
• Set up the primary machine to run Iguana and the DeltaCopy client;
• Start the connection between the primary machine and the backup machine;
• Create the synchronization schedule.

You will also need to know how to switch from the primary machine to the backup machine, and how to switch back to the primary machine.

The following sections describe these tasks.
