I agree, I logged in just to upvote the parent. Any copy is better than no copy, and if you don't risk damaging the original, I don't see the downside. This pragmatic preservation was already on my mind because of something that happened last night. I was driving on the motorway when a drunk driver caused a huge high speed crash right in front of me. I have a dash cam,and it captured the whole thing. The police officer on the scene used his body cam to film the incident from the screen of my dash cam. I'm sure it was a terrible copy, but it was an immediate backup. Of course he then collected my dash cam as evidence too. Their digital evidence team must be on point too because I got a thank you email within a couple of hours which said they had already successfully downloaded the original recording and were sending my dash cam back to me. Historians could learn a lot from this, ordinary police officers operating in difficult conditions are doing a better job of preservation than historians who's only job is preserving and studying historical artifacts under much easier conditions.
