This article taught me that just one backup isn’t enough to protect my important files. It explains the 3-2-1 rule: keep three copies, use two types of storage, and store one copy off-site. I learned about different backup types, like full, incremental, and differential, and why automation is key. The author stresses testing restores and not relying only on the cloud or RAID. The article gives simple steps and tools for anyone to start a solid backup plan. I found it clear, practical, and motivating—a fantastic guide for anyone who wants to keep their data safe.
