This patch adds asynchronous backup and restore functionality to Moodle. This is an optional feature and is not enabled by default. It can be enabled by site administrators. Asynchronous backup and restores are actioned by the Moodle adhoc task API. The progress of backup and restores is displayedin the Moodle UI. Users can also be sent a message when a backup or restore operation completes via the Moodle messaging API.
