    Use mariabackup for database backups

    Currently, Xtrabackup is used for database backups. However, Xtrabackup
    is not compatible with MariaDB 10.3. This change switches to use
    mariabackup [1], which is available in the mariadb image.

    The documented full and incremental restore procedures have been
    modified to use mariabackup, following [2] and [3].
