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

This plugin is an extension of UpdraftPlus: it adds a dashboard widget showing the date and time of the latest backup. It also displays how many edits were made after that, if any.
The plugin is currently available for use with UpdraftPlus Backup but it will ‘fail silently’ if used with another backup plugin (you will see a message telling you to make sure UpdraftPlus Backup plugin is installed and activated).
Please consider leaving a review if you have been using this plugin for a while.
