I needed to update to Joomla 3.7 and every time I did it ran an Akeeba backup. I already ran the back up before I started, so I just wanted to update the Joomla core.

You can do this by go into the Administrative area >> Extensions  >> and Plug-ins. Look for “System – Backup on update” and uncheck it.

This article helped me solve this.

I hope this helps someone else out there…
