Just One Category will cause WordPress to display on a category archive page 
only those posts which are direct members of that category, i.e. this plugin 
will exclude from that category page all posts which belong to any of that 
category’s subcategories but do not belong to the category itself.

Just One Category

On a category's archive page, displays only the posts directly in that category, not in any sub-categories.

A small plugin to exclude WordPress generated image thumbnails from Updraft backups, saving space. The original, full-sized image is included in backups, so if a restoration from backup is needed, WP CLI or a plugin can be used to regenerate thumbnails using the original, full-size images.
Features:
<ul>
<li>Works for all image types and includes both native and custom image sizes added by themes and plugins.</li>
</ul>

Exclude Image Thumbnails From UpdraftPlus Backups

I have been using your plugin for so long and never left a review. 

Thanks for this, changes my image-heavy backups of a couple of gigs to much less. Thanks again.

Works like a charm
