Mark Goddard 7f47ddf7f4 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].
