If your hosting is providing you
shell access, Drush (Drupal Shell) is a blessing if you want to make some repetitive actions faster, easier and more robust. The installation bit might be a little scary for new users (especially if it is the first time you hear the terms shell, bash, etc.) but it is definitely worth the effort.
With drush, among many many other things (e.g. install, update, enable/disable contributed modules), you can also:
backup (mysql dump) your database
reload/copy (mysql load) your database (some_database)
$ mysql some_database < backup.sql #load file into database
