How To Use WordPress Autosave And Post Revisions

Learn how to use the WordPress autosave and post revisions feature to restore and recover content revisions in your posts and pages.

WordPress Revisions And Autosave

Have you ever found yourself in a situation where, after spending a great deal of effort editing a blog post, something happens and you suddenly find that all of your hard work is lost because you didn’t hit the ‘Save’ button as you went along?

If this happens, don’t worry! WordPress comes with a powerful autosave and content recovery function that:

  • Helps to prevent losing your work if you forget to save,
  • Gets your page or post content back if your web browser crashes while you’re working, and,
  • Lets you restore an earlier draft if you’ve changed the content in your article.

This step-by-step tutorial explains how to use the WordPress autosave and revision feature to automatically restore content in your pages and posts.

WordPress Revisions And Autosave: Tutorial

Generally, after saving a post or page, you will see a notice like the one shown in the example below …

Edit Post - Post updated notification

(Edit Post – Post updated notice)

WordPress autosave and post revisions ensure that your content is saved periodically, allowing you to restore earlier post revisions when something unexpected should happen, for example:

  • The internet falls down,
  • Your internet browser freezes up,
  • You experience a power outage,
  • etc.

When you try to save your work, you may see a ‘WordPress Failure Notice’ like this instead …

(WordPress Post Save Error Message)

When you see the message “Are you sure you want to do this? Please try again” displayed and click on ‘Please try again’, you will normally go back to a screen displaying an older version of your post, minus any changes that you recently made.

This is where ’autosave’ can really save you time.

Autosave

The autosave function is automatically enabled for all WordPress pages and posts, but this does not overwrite any published content.

By default, posts are autosaved to your database every 60 seconds. This time interval can be changed by modifying code in your wp-config.php file.

Warning

We recommend making a complete backup of your data and files before modifying important website files.

Another improvement made after WP 4.6 is content recovery from loss of connection. If you lose your internet connection while writing, your drafts are saved locally to your browser. When you return to edit, WordPress notifies you if there is a more recent draft, allowing you to restore the most recent version of your content …

What Is The Post Revisions Feature?

The Post Revisions feature was introduced to WordPress in v. 2.6. Whenever a post or a page is saved in WordPress, a revision is automatically created and stored in the WP database.

Significant enhancements were made to the post revision control system after WP 3.6.

The new revision system now includes a new option to the Post/Page Publish box called Revisions. This allows you to know at a glance how many revisions you have made. and allows you to easily access the ‘Revisions’ section by clicking on the ‘Browse’ link …

WordPress Post Revisions Feature – Additional Notes

As mentioned earlier, there are some changes you can make to the WordPress revisions feature such as changing the autosave interval or even disabling the feature altogether, but these typically require modifying code in core files. If you feel worried about editing files inside your web server, then contact your web host or get professional assistance.

Let’s focus, then, on some additional aspects of WordPress post revisions that don’t require editing code.

Viewing The WordPress Post Revisions List – Post Editor Section

As soon as you create, edit, and update posts and pages, WordPress begins to store new post revisions in its database. These appear in a Revisions list at the bottom of your page or post …

Managing Content Revisions – WordPress Plugins

Autosave and post revisions are no doubt functions that help create a more effective workflow. If you write or edit a lot of content, however, the number of revisions can start to build up. This can significantly grow the size of your WordPress database, so it’s important to be able to manage your revisions.

Post revisions can really add up after a while

(Your database could be storing lots of unnecessary data)

For example, if there are 200 posts on your site with an average of 10 revisions each your WordPress database could be storing around 3,000 copies of old data. If your post is approximately 100KB data, then with 3,000 revisions of that post, the total space wasted is about 300MB.

The good news is that there are various WordPress plugins available to help you control and manage your revisions and reduce the size of your WordPress database.
