Architecture

Each Double-Take installation has several key components.

• Driver—Double-Take file system drivers identify file changes on the source as they occur.
• Engine—The Double-Take engine transmits the replicated data between the source and target servers.

• Management Service—The Management Service hosts the Job Manager, which is a web service that creates, monitors, and controls the Double-Take job. The Management Service offers a SOAP-based XML web services interface.

  

• Communication—Regardless of your client type, the majority of communication from the client will be to the target server. There is minimal communication between the client and the source. The source to target communication is handled directly by the engine.
