Tip: Every good backup strategy follows the 3-2-1 backup rule: 3 copies of your data with 2 media types and 1 off-site. The first backup, typically stored on-site, protects you from accidents or hardware failure and ensures that you can restore your data as quickly as possible. The second backup, stored off-site, protects you against disasters, so that if the worst happens, you can retrieve your data and move forward. Watch YouTube Video
