A Veeam engineer needs to copy backup files from a Windows repository in Site A to a Linux repository in Site B. The WAN connection between the two…

The Backup Copy Window is a specific feature within the backup copy job configuration designed to control network traffic. It allows an administrator to define permitted and prohibited times for data transfer. By setting up a window that excludes business hours, the engineer ensures that the backup copy job will only transfer data over the WAN connection during off-peak times, such as nights and weekends. This directly fulfills the requirement to avoid network congestion during the busy workday.

A. Immediate copy: This mode begins copying new restore points as soon as they are created, which would cause data transfer during business hours if the primary job runs then.

B. Periodic copy: This mode defines the synchronization interval (e.g., every 4 hours) but does not, by itself, prevent transfers from occurring during specific prohibited times.

C. WAN accelerator: This feature reduces the amount of data sent over the WAN but does not control the schedule or timing of when the data transfer occurs.

"Define a Schedule for the Job" section: "You can define a time window for the backup copy job. The backup copy job will be performed only within this window. If the job exceeds the allowed window

it will be automatically terminated." This explicitly describes the function of the Backup Copy Window.

"Backup Copy

" Page ID: vspherebackupcopy.html: This document outlines the two copy modes: "Immediate copy" and "Periodic copy." It clarifies that these modes determine the start condition and frequency of the copy cycle

not the allowed transfer times.

"WAN Acceleration" section: "WAN accelerators are optional components in the backup infrastructure that are used for Backup Copy and Replication jobs... to optimize data transfer over a slow WAN connection." This confirms that its purpose is optimization

not scheduling.
