Since WordPress 2.6 WordPress has incorporated two new features designed to make editing pages and posts easier and more secure.
These features are designed to allow you to recover from connection errors and editing mistakes. The features are called Autosave and Revisions.
The video below overview of the Autosave and revision features and how they are used. Showing how to recover a previous page/post and how to revert back to an auto saved version of a post/page.
You can also watch on Youtube.lease don’t forget to comment.
You are allowed 25 revisions which are created when you manually save/update a page or post but only one auto save.
While you are editing a page/post any changed are automatically save every minute each auto save overwrites the previous one.
If you have browser crash or loose connection to the WordPress server or just forget to save your edits then the auto save feature can be used to restore your edits.
You cannot turn the features off in the WordPress settings they are present and enabled by default.
However by changes to the wp-config file you can modify the autosave interval (6o seconds) and turnoff revisions.(not recommended)-http://codex.wordpress.org/Editing_wp-config.php
