A Python script to automate SQL dumps via phpMyAdmin's web interface

phpmyadmin_sql_backup.py

What is it?

A Python 3 script to automate the download of SQL backups via a phpMyAdmin web interface.

This is useful when your web hosting provider does not grant you access to a console (for mysqldump) but you want to automate the backup of your database (without having to manually use the browser).

It has been tested with Python 3.4+ on Linux and Windows and the following versions of phpMyAdmin: 4.3.x - 4.8.x, 5.0.0

Note: The web interface of phpMyAdmin may change in the future and break this script. Please file a bug report (including your version of phpMyAdmin) if you encounter this issue.

---

phpmyadmin_sql_backup.py "http://www.example.com/phpmyadmin/" your_user your_password --exclude-dbs mydb2,mydb4 --prepend-date --basename example_dump --output-directory /tmp --compression zip

Downloads a zipped dump with databases mydb2 & mydb4 excluded, the base name example_dump and a prepended UTC date / time to the directory /tmp, e.g. /tmp/2016-03-11--15-19-04-UTC_example_dump.zip.

Requirements

• A Python 3.4+ installation on your system
• Grab - python web-scraping framework: Install via pip install -U Grab or see the installation instructions if you run into problems.

Note for Windows users: while it is possible to install the requirements natively, it is often easier to use the Windows Subsystem for Linux if you are using Windows 10
