Subversion

Management software manages the different versions of your project, pools it together and backs up your files with every modification. When you work on several projects such as a website with subversion you do not have to worry about the code.

Subversion allows you to share the work of individual members to the entire team and to revert to a previous version in a single command.
For example: a developer works on a file and when finished sends the new version to subversion which is available to the entire team. If there are many people working on the same file, the software saves the changes made between the two versions and aggregates these changes into one file. If necessary, you can access versions and their differences - no work is lost.

Part of your online project (in production) is managed by subversion as if it was a classic subversion account. You can update all or part of your project online with peace of mind, without risk of data loss or conflicts between the file versions.

To install Subversion on your hosting you can follow this guide.
