What is MySQLDumper ?

MySQLDumper is a PHP and Perl based tool for backing up MySQL databases. You can easily dump your data into a backup file and - if needed - restore it. It is especially suited for shared hosting webspaces, where you don't have shell access. MySQLDumper is an open source project and released under the GNU-license.

The problem …

A PHP script has a maximum execution time that is usually set to 30 seconds on most server installations. A script running longer than this limit will simply stop working. This behavior makes backing up large databases impossible. Maybe you already had this specific problem when using other tools.

MySQLDumper fills a gap …

MySQLDumper uses a proprietary technique to avoid this problem. It only reads and saves a certain amount of data, then calls itself recursively via JavaScript and remembers how far in the backup process it was. The script then resumes backing up from that point.

The restore process is similar. Unlike other tools, splitting and splicing of large backup files is no longer necessary.

MySQLDumper can write the data directly into a compressed .gz file. The restore script is able to read this file directly without unpacking it. You can also use the script without compression, but using Gzip saves a lot of bandwidth. You can even configure the script to automatically send the backup file to an FTP account or your email adress.
