Overview

In many cases, the Code42 app's default memory setting supports backing up as much as 1 TB of data or as many as 1 million files on Mac and Linux devices, and as much as 4 TB of data or as many as 4 millions files on Windows devices. However, you may need to assign additional system memory if the Code42 app:
