SQL-GD Peforms a Drush sql-dump and creates the filename with the following components: current branch, ISO 8601 date (YYYY-MM-DD) and the seven character SHA-1 commit hash.

A dump file created with this script will look something like this:

backup/develop_2013-08-12_e970d31.sql

• For brevity, time is not included in the date component. Instead the filename is auto-incremented if it already exists.
• Currently, a backup/ directory at the same level as the web document root is required to exist.
• Underscores are used to separate components

I recommend creating a Drush shell alias pointing to this script. In drushrc.php, add:

$options['shell-aliases']['sql-gd'] = "!drush scr /path/to/sql-gd.php";
