      1. Turn on full debugging
      2. Go to Site administration / ►Courses / ►Backups / ►Automated backup setup
      3. Set the following:-
        1. backup_auto_active - Enabled
        2. backup_auto_storage - Specified directory for automated backups
        3. backup_auto_destination - Path to a folder that doesn't exist
        4. Use course name in backup filename - checked
        5. backup_auto_skip_modif_days - never
        6. backup_auto_skip_modif_prev - unchecked
      4. Run php php admin/cli/automated_backups.php
      5. Make sure you get logs like:- 

        Specified backup directory is not writable -  /ankit/moodles/stable_master/backup

      6. Go to Site admin>reports>backups
      7. Make sure status of all courses that were backed up is "Error"
      8. Make sure no new backup is generated in "course automated backup area" (click on course >restore)
      9. set 'backup_auto_destination' to null, by making the input box empty.
      10. Run php php admin/cli/automated_backups.php
      11. Make sure you get logs like:- 

        No directory specified for automated backups

      12. Go to Site admin>reports>backups
      13. Make sure status of all courses that were backed up is "warning"
      14. Check course backup area, make sure there is a new backup.
      15. Now test again with a proper writable directory and make sure backups are generated properly.
      16. Now repeat everything with 'backup_auto_storage' set to "Course backup filearea and specified directory"
      17. Now set 'backup_autostorage' to 'course backup filearea' and run the backup tool. Make sure no errors are noticed in the out put. View the backup report and make sure the status of backups are "OK".
      18. Do exploratory testing with automated backups to make sure nothing is broken.

    • BACKEND Sprint 19

      We have incorrect precedence of && and || operators in automated backups.
      In backup/util/helper/backup_cron_helper.class.php we have

                  } else if (!file_exists($dir) || !is_dir($dir) || !is_writable($dir) && $storage !== 0) {

      which should be

      } else if ((!file_exists($dir) || !is_dir($dir) || !is_writable($dir)) && $storage !== 0) {

      Since that branch should be executed only if $storage !== 0

      This leads to the problem that when backup_auto_storage is set to "course backup filearea" and backup_auto_destination is empty (i.e. the default settings), no backups happen since $storage is set to 0 in this case.
