Our cyber insurance demands backup evidence and immutable storage, how do we deliver?

Insurers have tightened up: without proof of working immutable backups you don't get a policy or you pay more. The requirements tend to be well-founded and actually raise your security baseline.

Try this first

1. 1Read the policy questionnaire carefully and tie each question to the exact tool, frequency and retention. Vague 'yes we have backup' is a claim-time risk.
2. 2Provide evidence: 3 months of backup reports, screenshots of Object Lock or immutable policy, and logs of a successful restore test.
3. 3Common requirements: daily backup, immutable or air-gapped, tested, off-site, with success and failure logging. Align your tooling before applying.
4. 4At claim time you'll need the same evidence in sharper detail: date of last verified-clean backup, percentage of data recovered, time taken. Document in real time.
5. 5Don't negotiate the facts but do negotiate definitions. 'Immutable' can mean S3 Object Lock, Veeam hardened repo, or tape, ask if your setup qualifies before redesigning.
6. 6Keep policy requirements aligned with your backup stack. Yearly review, plus a quick check after every major infra change.
