Plesk Onyx VPS Disk Space Usage

Overview

The disk space is the total amount of data that can be stored on your server at any one point in time. For a Virtual Private Server (VPS), this includes both your the files for your website as well as the system level files including logs and system libraries. You can quickly determine if the excess usage is due to a website by viewing the usage per website and comparing to the total space available.
