Does Upraft Plus Create Old Versions of Files in

Hey, does Updraft Plus leave several versions of the files in wp-content?

For example, in the wp-content directory, I currently have the following files:

litespeed
litespeed-old
litespeed-old-old
index.php
index.php-old
index.php-old-old
etc

I have no idea what is causing. Please let me know if this is an Updraft Plus feature.

Thanks!
