First it is necessary to create a backup user on the database which has (only) read access to everything. This is because its password will be embedded in the backup script which reduces security. This can be done with:
BKUSR=backup
BKPW=backuppassword
BKDIR=/var/www/dbbackup
mkdir -p $BKDIR
echo "GRANT SELECT, LOCK TABLES ON *.* TO '$BKUSR'@'localhost' IDENTIFIED BY '$BKPW'; FLUSH PRIVILEGES;" | mysql -u root -p
In the backup script, first some variables are set up
BKUSR=backup
BKPW=backuppassword
BKDIR=/var/www/dbbackup
SITE=cfaw.info
