      1. If you don't already have one, create the 'M' size course using MDL-38197.
      2. If you don't already have one, do a backup of the course (continue through all screens using default settings).
      3. Click 'Restore' link against the backup so that the first restore screen loads.

      EXPECTED:

      About five seconds after the page header appears, you should see a progress bar which indicates unzip progress. The progress bar should move across until the unzip finishes (which is usually before it reaches 100% - the percentage isn't very accurate). At that point it should disappear and the confirm screen should appear as normal.

      4. Continue through the restore process, restoring to a new course, until the restore actually completes. (Just to confirm the new code hasn't caused an error somewhere else.)

      I finally got a backup of a large course (the 'L' size from MDL-38197) to complete successfully, resulting in a 900MB backup.

      Unfortunately, this cannot be restored. On the first step of restore, I get this error:

      Fatal error: Maximum execution time of 120 seconds exceeded in /fs1/www_root/sm449/coremoodle/lib/filestorage/zip_archive.php on line 247

      I think the system needs to display progress during the unzip. (Progress is needed during the zip too for backup - see MDL-41087 - so I'll try to build API changes that can also be used for that.)
