When you work on a raw file you don't actually change it - you just give your raw processing software a set of instructions on how to interpret the raw data when presenting it to your post processing programme. PS & Lightroom then store this data for future use (and further tweaking) andgive you the option of either using the cache, or in a separate sidecar file with a xmp extension, which is what I do so I can share the raw & xmp files between my laptop when taking pictures on site, and my desktop for later processing - so there's no need to duplicate your raw files.
There is a school of though that suggest that your convert you manufactures native raw files to Adobes open source raw files which have a dng extension (digital negative) the idea being that they will still be readable if the manufactures stop support for some raw formats as time goes on ... but its not something I do - does anyone else?
