Your hosted Moodle will contain a lot of very important data such as coursework, assignments, grades, and all administrative data, for example users and roles. Therefore, it is vital that you have a good backup strategy in place.
Moodle supports two types of backups:
Course backups are usually run on an ad hoc basis, and only save the selected course. You will learn about how to create course backups, how to restore courses and the related course import facility.
The site backup option saves all courses and their related data to a specified location at regular intervals. You will learn how to set this up and recover data from it.
Both mechanisms will be covered in detail before we look at system-level backups, which includes Moodle backups (covering the Moodle software as well as the data stored in it) and snapshot creation (full system images).
