Quick tip in backing up and restore your MySQL database:

Backing up and Restoring MySQL database

Backing up database:
Syntax:
mysqldump -u [username] -p [password] [databasename] > [backupfile.sql]
o    [username] -database username
o    [password] -password for your database
o    [databasename] – the name of your database
o    [backupfile.sql] – the file to which the backup should be written.
Example:
mysqldump -u root -p asterisk > asteriskbackupmarch3.sql
(just input the password when prompt for password)

Multiple database:

Syntax:
mysqldump -u [username] -p [password] –databases  [databasename1] [databasename2] > [backupfile.sql]

Example:
mysqldump -u asteriskuser -p –databases asterisk asteriskcdrdb > multibackup.sql
(then input db password)
