3-2-1 rule explained for client proposals

Overview

The 3-2-1 rule—three copies of data, on two media types, with one off-site—survives because it is simple for executives to remember.

How to present it

• Translate to their workloads: ERP, files, M365, VMs.
• Show what you actually deliver: backup product, immutability, DR site, tested restores.

Pitfalls

Cloud-only “two copies in one vendor” may violate insurance; clarify vendor architecture honestly.

Proposal snippet

“We maintain production data, local appliance cache, and immutable off-site copy with quarterly restore tests recorded.”

Upsell tie-in

DR runbooks and tabletop exercises as separate line items when risk warrants.
