FAQ
What is 3-2-1?+–
Three copies, two media types, one off-site/offline. Variants add immutability (3-2-1-1-0).
Does DR equal BC?+–
DR is IT recovery. Business continuity also covers people, sites, and manual workarounds.
How often to test restores?+–
At least annually for every critical system; quarterly is common for the most critical.
Are cloud snapshots enough?+–
They help but account-level compromise can delete snapshots unless immutability/separation exists.
