As a backup plugin, UpdraftPlus will use plenty of I/O (input/output) resources and CPU. If your website is small – e.g. just made up of some blog posts, and reasonably-sized images, then all this may not amount to much. If, on the other hand, you’ve uploaded lots of large resources (e.g. videos, audio files, or huge images) or if your site is very big and popular (e.g. has vast numbers of comments), then it may amount to more.

There is no need to uninstall this plugin but you can refer the suggestions in this update to reduce the CPU usage caused by the updraft-plus plugin.

Here are the steps to limit the resource usage:

1. Configure the timing of your backup to run overnight – via the “Fix Backup Time” add-on, if you don’t already have it. In the “small hours” of the morning, servers are usually very lightly loaded, with lots of spare resources.

2. Check that you don’t have any plugins that create enormous, mostly useless, database tables (e.g. some statistics plugins that record a new row in the database for every single visitor)

3. If you store a lot of files, then go into the ‘Expert settings’ section of the UpdraftPlus page, and reduce the default setting for how much data is stored in each zip file. e.g. Reduce it from the default of 800Mb down to 100Mb. This will mean that UpdraftPlus spends less time in manipulating large zip files – which can use a lot of resources and be quite time-consuming, especially on slower servers.
If you have a collection of large, unchanging files (e.g. historic audio/video), then you could take a one-time backup of these, store them somewhere safe and then after that exclude them from the UpdraftPlus backup using the exclusion options in UpdraftPlus. That will then save the time/resource usage that zipping them up into the UpdraftPlus backup would have taken.

We could see many images under the /uploads/2014/03 , /2014/08, /2014/10, /2014/11 folder. As there are many image files, we are not having any idea regarding the image files that has to be removed. You can delete the unwanted files from cPanel >> File Manager >> Navigate to the uploads folder >> select the image >> Delete.
