CourseBank is a cloud backup solution for your Moodle courses. From a plugin available as an admin tool, you can send backups of your courses to the cloud and retrieve them. It takes care of keeping the course structure, which is not always an easy thing to do manually, and putting all your content into place. We reported its launch last September, and since then, lead developer Adam Riddell and Co. have kept busy, fixing issues as they appear.
Updates to CourseBank include the ability to drop old backups from local storage. You can also manage copies of your courses from the plugin. No need to leave Moodle. Currently around 60 websites use CourseBank.
CourseBank supports Moodle 2.4 to 3.1. To use CourseBank you need to sign up for a free account. This will give you 5 GB of cloud storage. Catalyst powers CourseBank with their own servers, which dwell in New Zealand.
