I've lost close to a thousand of files over the years due to poor habits when it comes to backing up my music. I honestly just recently started backing music up weekly and it helps me sleep better at night knowing I got my files backed up. I watch this show on youtube called Pensado's Place from time to time and they have a segment where they drop technical gems.
They had some guy come in from Sweetwater Sound talking about Hard Drive etiquette. Really some insightful stuff. When you have time def check it out. Its on our Instagram IGTV you can check it out here.
