It may be useful to make a backup of a specific database through the command line. Surely it is easier to use tools like phpMyAdmin, but in case of emergency or because you prefer use the shell, this info is certainly useful. The executable that performs the operation is “mysqldump” which is usually installed with the MySQL server.

mysqldump -h localhost -u username -p database_name > database_backup.sql

Obviously the parameters changed accordingly, localhost should be fine considering the use of the shell, while database_name username must be adjusted accordingly. After the sign > is the name chosen at your discretion. Once given the command will be prompted for a password to access the database to its content.

Can also directly produce a compressed slightly by changing the syntax as follows:

mysqldump -h localhost -u username -p database_name | gzip -9 > database_backup.sql.gz

where performs gzip compression (-9 parameter indicates the best compression possible), this is useful if you download the file through the Internet.

Whoops.. in Windows Vista and Seven the UAC (User Account Control) force the run (windows key + R) to running in your own userlevel. If you run CMD, the shell don’t have administrator privileges. Really boring, if you want to run some command in admin you have to follow this easy steps.

Choose from Start -> All programs -> Accessories, right click on Command prompt and Run as Administrator. You’ll be prompted to approve the action.
