This one used car website supposedly doesn't keep archives because of volume of ads. But I need to get an ad posted in 2015 which shows that the car dealer put up the ad not private individual. I had it but my backup didn't work and I lost it. I know that police/FBI forensics can get this off the server because they do it all the time in homicides. I know I need a subpoena but does anyone know how to specifically get the deleted files and how to fill out subpoena to get that done?
Software/Hardware used: I don't know OS for website, they won't tell me
