@KnyteTech Copying the files should be fine - make sure you keep the same folder structure. TBH, I make it habit to have a working copy of the entire contents of the SD card on a PC which is then backed up to my NAS and also to cloud storage. I only ever edit or add files on the PC and upload them to the SD card - never the other way round. That way, I can always create a new SD card if and when the worst happens.
