What must be done prior to executing any type of backup or restore?

Making a directory is essential prior to executing any type of backup or restore because it provides a designated location where the backup files can be stored or from which they can be retrieved. This step ensures that there is an organized structure in place for managing your data effectively. Having a specific directory helps in preventing loss of data and facilitates easier access during the restoration process, as well as ensuring that the necessary permissions and storage capacity are accounted for.

Creating a backup file cannot occur without an appropriate directory to store the data, as this directory serves as the target location for the backup. Simply powering off the controller would not prepare the system for a backup or restore process, and notifying the operator, while important for communication and workflow, does not directly impact the technical requirements for performing a backup or restore. Therefore, establishing a directory is a fundamental step in this process.
