WordPress provides post revisions. A great way to step back to a prior version of your post!
Whilst writing blog posts I’ve used the post revisions to check a previous version of a paragraph, or idea. and that all important recovery of a post which has had parts deleted in error.
The post revisions are shown on the right hand side of the Edit Post screen, within the Publish section.
How to enable the post revisions.
If the post revisions aren’t showing
At the top of the page there’s a tab marked as Screen Options. Click on this to expand.
Within this area are the content options which may be displayed. Check that the Revisions check box is ticked.
Click on Screen Options again to close.
The post revisions option will only show once you have saved the post a number of times.

I have also seen it written that adding
to the file wp-config.php in the root of your website may also be required. I’ve not found that I needed to add this.
Rather than filling the database with lots of post revisions, potentially slowing your website, you can limit the number of post revisions. I like to set this to 20 maximum.
In summary to be able to view the previous post revisions of your blog port ensure that the Revisions check box is ticked in the Screen Options and you’ll need a history of post revisions before it is shown.
