Acronis Back-up - Not Deleting Previous Back-up Filling My Port

I have a non supported WD - My Passport. Acronis True Image is now doing the back-up to My Passport. I do a daily Incremental back-up and then on every 5 incremental back-up it does an automatic full back-up. The problem is it does not automatically delete the previous full back-up(s) and eventually it fills up my 1 TB of My Passport space. There does not seem to be a way of setting Acronis Ture Image to auto delete previous full back-ups; if there is does anyone know how to set it?

Thank you!

Hi @Waynef52,

Thank you for your reply. Since My Passport is no longer supported by WD I was told that I should download and use Acronis True Image to back up my hard drive files. The Acronis download was on the WD support MY Passport download. If I understand what you are saying, instead of Acronis True Image I should be using some back-up function in Windows 10?
