MySQL/MariaDB mysqldump command

Although there are different methods for backing up MySQL and MariaDB databases, the most common and effective one is to use a native tool that both MySQL and MariaDB make available for this purpose: the mysqldump command. As its name suggests, this is a command-line executable program that allows you to perform a complete export (dump) of all the contents of a database or even all the databases in a running MySQL or MariaDB instance. Of course it also allows partial backups, i.e. only some specific tables, or even only only a subset of all the records in a table.

The mysqldump command offers a multitude of different parameters that make it very powerful and flexible. Since having so many options can be confusing, in this post I am going to collect several of the most frequent usage examples with the most common parameters and that are most useful in the day to day life of the system administrator.

Using PHP to backup MySQL databases


This post shows how to perform a partial or full backup of MySQL databases using only PHP code. This is very useful for example when a client doesn’t provide you with access data to the database of a web application and you only have an FTP connection available, or when you do have the connection data to the database but you can’t access it through the network (only available from localhost) and you can’t use tools like mysqldump to back up the information you need because you don’t have privileges for this, or simply because you have no access to a shell to which connect and run commands.

UPDATE (08-28-2017): moved the source code from myphp-backup.php and myphp-restore.php scripts to my GitHub daniloaz/myphp-backup repository
