Correct Answer: ATo transfer backups from Site B to Site A efficiently, especially when the direct connection cannot complete within the backup window, a backup copy job is ideal. A backup copy job allows for asynchronous replication of backup data, ensuring data protection and restore options are available at Site A. The correct sequence of components starts with the repository at Site B (component 6), which sends data to the WAN accelerator at Site B (component 4). The data then travels over the WAN and is received by the WAN accelerator at Site A (component 3), and finally lands in the repository at Site A (component 2). Proxy servers are not required in the backup copy job process. This configuration leverages WAN accelerators to optimize data transfer across the WAN, ensuring backups are completed within the allocated window.
