/backup Command Configuration

[DylooOfficial]

          So in my server, I was testing out some commands, and one of them was /backup, and when i try to use it, it states that;

Error: An external backup script has not been configured.

            I'd like to know if their is a way to configure that command to be able to backup my server from inside it, without going to my website, or using, like a OneDrive or Google Drive. 

The /backup command is part of the Essentials Plugin.

I did find this Reddit post:

        And it kinda explains how it can clone any file and have it go into a certain directory in the cloud of your preference, but I'm unsure as to how to get it working in Mine hut, if it could even work.

Thank You,
