I'm not sure its an option for you, but the best way to go about this is what Tata and AndySavage already said: to take a snapshot of the data files from the production server and then install them on your local box by using Percona's innobackupex. It will backup InnoDb tables in a consistent way and perform a write lock on MyISAM tables.

Prepare a full backup on the production machine:

Copy (or pipe via SSH while making the backup - more info here) the backed up files to your local machine and restore them:

Restore the backup:

You can find the full documentation of innobackupex here: http://www.percona.com/doc/percona-xtrabackup/2.1/innobackupex/innobackupex_script.html

The restoration time will be MUCH faster than reading an SQL dump.
