This Laravel 5 package provides an artisan command to dump your database to a file. When installed you can dump your database with this command
php artisan db:backup
A file containing the dump of your database will be created in the directory you specified in the config-file.
I plan on adding support for using Laravel 5 Cloud storage in the near future. It will then be possible your dump on cloud based storage such as S3 or Dropbox.
