Secure Testing and Development

Develop locally, deploy globally

Develop and test your site on a local machine first. Installing Joomla locally is not as hard as it may sound, and the exercise will greatly boost your confidence.</li>

Use an IDE

Consider using an Integrated Development Environment (IDE). One free IDE that many Joomla! developers use is Eclipse. See Setting up your workstation for Eclipse development for instructions on installing Eclipse.

Use a versioning system

Be able to roll back to an earlier version of your site using a modern version control system, such as CVS, Subversion, or git.</li> The Eclipse IDE indicated above includes a Subversion plugin. This allows you to work with the Joomla! source repository as well as other projects hosted on JoomlaCode.

Setup a backup process first

The most important rule

Thou shalt at all time be able to return your site to a previous working state through regular use of a strong, off-site backup and recovery process.

Be sure your backup and recovery process is ready and tested BEFORE your site goes live.

This is the single best way (and often the only way) to recover from such inevitable catastrophes as:

1. A compromised/cracked site.
2. Broken site due to a faulty upgrade.
3. Hardware failure, such as dead hard drives, power failures, server theft, etc.
4. Authoritarian government intervention. (More common than some think.)
5. Needing to quickly relocate to a new server or hosting provider.
