Always keep or protect original image

[Perseus83]

While editing a specific image I can only select to "save" and overwrite the original image or to "save as" new image.

While working with other image editing tools, I'm used to have a feature that always protects the original image.
Is there a way to set something alike?

Thanks a lot!

you don't want that 'Save' is available?
