Course backup

Note for Contributors This page should explain what can be seen on the moodlesite.com/backup/backup.php page when backing up a course
Generally, you will not have to worry about backup as the primary Moodle administrator has set a schedule of site wide backups. However, it is a best management practice to perform a course backup at regular intervals, and to store this backup locally on your computer. After clicking the Backup link you will see options for specific activities you wish to backup. Simply follow the on-screen instructions to complete a backup.
