Create a backup copy of a MySQL database on the same host

mysqldump OLD_DB | cat <(echo "CREATE DATABASE NEW_DB; USE NEW_DB;") - | mysql
This should probably only be used for testing in a dev environment as it's not terribly efficient, but if you're doing something that might trash a DB and you still want the old data available, this works like a charm.

What Others Think

Seems a little more direct: (echo "CREATE DATABASE NEW_DB; USE NEW_DB;";mysqldump OLD_DB;)|mysql
