To connect to mysql, backupninja must authenticate.
There are three possible authentication methods:
USER
With this method, you specify a system user. Backupninja will
then become this user before running mysqldump or mysqlhotcopy.
The result is that ~/.my.cnf is used for authentication.
PASSWORD
With this method, you manually specify a mysql user and
password in the backup action configuration.
DEBIAN
With this method, we use the debian-sys-maint user which is
already defined in /etc/mysql/debian.cnf. If you are running
debian, this is recommended, because no further configuration
is needed. The drawback is that this is incompatible with
mysqlhotcopy: you must use mysqldump.
