Inside your drupal installation
$> drush archive-dump

/root/drush-backups/archive-dump/20150228093558/mysite.20150228_093559.tar.gz

2) local server
1. go to mysql console and set up the same mysql credentials you had for your mysql drupal database

mysql> create user 'myuser'@localhost identified by 'xxpasswordxx';
mysql> grant all privileges on *.* to 'myuser'@'localhost';
mysql> set password for 'myuser'@'localhost'=password('xxnewpasswordxx');

2. restore
go to /var/www/html and run
