Say you ssh into a server as the user `deployer` and have a folder on the server `~/dump`:

```sh
# on the server you are logged into
# backup the database
mysqldump -uroot -pstrongPassword railsapp_staging > ~/dump/YYYYMMDD_railsapp_staging.sql

# next logout/exit your ssh session to the server above
exit

# now download the backup from the above server
# say you have a folder db/dump in the local folder you are in
scp deployer@aboveserver.com:dump/YYYYMMDD_railsapp_staging.sql db/dump/.

# restore from backup file to local development mysql
mysql -uroot -plocalPassword railsapp_staging < YYYYMMDD_railsapp_staging.sql
