What must be verified before executing any type of backup or restore?

Before executing any backup or restore operations, it is crucial to set the default device or verify that the correct device is selected. This ensures that the data is being backed up to or restored from the intended storage medium. If the wrong device is used, it can lead to the loss of data or the restoration of incorrect data, which can significantly impact the operational integrity of the controller and the systems reliant on it.

Verifying the device is a critical step as it ensures that the system recognizes where data will be drawn from or sent to. For example, if a technician intended to backup to a USB drive but had the system set to an internal drive instead, the backup could overwrite essential files or fail entirely. Therefore, confirming that the correct device is configured avoids potential data corruption or loss and maintains a safe operational environment.

Having the controller powered on, confirming software updates, or checking battery levels are all important maintenance tasks, but they do not directly ensure that the backup or restore process will be successful. Power status is indeed necessary for operation, but it does not determine the integrity of the process without the right device being selected. Similarly, while it is good practice to have the latest software updates installed for optimal performance, they do not affect the immediate task of
