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

An UpdraftPlus extension that excludes image size thumbnails, generated by WordPress, from Updraft backups.

This plugin disables the admin notice from UpdraftPlus that warns the user that ‘DISABLE_WP_CRON’ is enabled. However, if the site is relying upon the server’s crontab, the notice is just in the way.
Features:
<ul>
<li>A very simple plugin. Just install and activate, and the ‘DISABLE_WP_CRON’ notice is gone.</li>
</ul>
