What is the 3-2-1 backup rule and why is it important for photographers?

• A. 3 copies of data, 2 local on different drives, 1 offsite.
• B. Three copies of data, all stored locally.
• C. 2 copies of data on the same drive.
• D. 1 copy of data stored in the cloud only.

Answer: (B)

Having multiple backups in different locations and on different media protects against data loss. The 3-2-1 rule means you should have three copies of your data in total, two stored locally on different drives or devices, and one kept offsite (such as in the cloud or at a separate location). This matters for photographers because RAW files are valuable and time-consuming to recreate, and hardware failures, theft, fires, or floods can wipe out everything if all copies are in one place. With two local copies on different media, you’re protected against a single drive failing, and with an offsite copy, you’re protected against local disasters. The option that suggests all copies are local misses the critical offsite piece, leaving you vulnerable to broader risks. Practical tips include automating backups, regularly testing restores, and using reliable drives alongside a trusted offsite solution.
