Back ups suggestions

Back ups suggestions

I have 3 main suggestions for back ups
  • automatically delete oldest when you reach the limit of back ups
  • have more than 3 back ups per application
  • rename back ups

I have an application which I want to back up regularly. When I go to back it up, I see the following message,  "Already three backup's for this application assets is present. You are allowed to have only three copies"
I always have to delete the older back up before I can click the back up button.   Can you automatically delete the oldest back up via the prompt before proceeding with the back up? 

Also, is there a way to have more than 3 back ups per application? To be extra safe, I would rather have more if it was possible.

Also, can you rename back ups or allow users to give back ups a description?
