Keep data recoverable
A solid backup strategy keeps three copies on two media with one offsite, sets retention for versions, encrypts at rest, and regularly tests restores so data is actually recoverable.

Design
Use 3-2-1: primary, onsite backup, offsite/cloud; encrypt and label owners.

Test
Run periodic restore drills to verify integrity and runbooks.
