Re: [4.4.2]Error on automated backup, core\task\course_backup_task,array_key_exists(): Argument #2 ($array) must be of type array, null given

Hi Richard,

When I look in the tgz_packer.php file, it is the writing of a file to system :

$written += gzwrite($gz, $data);

Maybe a problem with your data storage that fails to write?

The class is handling this function:

* Utility class - handles all packing/unpacking of .tar.gz files.
