Being an IT guy I baxkup EVERYTHING multiple times. I was shocked when I actually stopped and figured out how many copies of everything I DO keep.
- Laptop at work
- Desktop at work
- 32GB Thumb drive (just for documents and downloads)
- 500GB Passport USB drive
- Home laptop
- Home server
- 4 count 'em 4 backups to a 1TB USB drive at home
That makes 10 copies! I've just gotten burnt to many times by hardware or human error. So I just kept adding more and more copies.
Haven't lost anything in years.
