◈ Disaster recovery

A plan you have
run. Not a plan
you have written.

Most disaster recovery is a document. It describes a procedure nobody has performed, with assumptions nobody has tested, and it will be read for the first time on the worst day of the year.

Used for recovery, continuity, backup verification and failover.

What holds true here

Four things you stop arguing about

◆

Rehearsed, not written

Recovery is something you have done, repeatedly, rather than something you have described.

◇

Backups that are verified

A backup nobody has restored is a hypothesis. Verification happens without anyone scheduling it.

◈

Recovery points in moments

How much work a failure could cost you, measured in moments rather than in hours of re-entry.

○

Evidence for the regulator

Proof that recovery works, drawn from exercises that actually happened.

The shift

From a document to a drill

Every organisation that has had a bad recovery had a recovery plan. The plan was not the problem; the fact that it had never been executed was.

The usual arrangement
  • ✕A plan last tested at an unknown date
  • ✕Backups taken and never restored
  • ✕A recovery point of hours, discovered late
  • ✕Failover attempted for the first time live
  • ✕Continuity evidence written, not demonstrated
What replaces it
  • ✓Recovery exercised as routine
  • ✓Backups verified by restoring them
  • ✓A recovery point you know, because you measured it
  • ✓Failover performed before you needed it
  • ✓Evidence that is a record of real exercises
What you can count on

Disaster Recovery, specifically

The drill that was boring

The goal of a recovery exercise is for it to be dull. Everyone knows the steps because they have done them, the recovery point is the one documented, and the exercise ends early. A dramatic drill is not a successful one — it is a preview.

Restores that are tested

Backups verified by being restored, which is the only verification that means anything.

Any point in time

Recovering to a moment rather than to last night’s snapshot.

Failover you have used

Regional and provider failover exercised before the day it matters.

Evidence as a by-product

Continuity proof that comes from exercises instead of from a drafting session.

We had a real incident eight months in. It went exactly like the drill, including how long it took. Nobody had to make a decision under pressure.

Questions we are actually asked

Answers without the hedging

What is our recovery point, concretely?+

Moments rather than hours for most workloads — and more importantly, a number you have measured during an exercise rather than one in a document.

How do we know our backups work?+

Because they are restored. A backup that has never been restored is an assumption, however well-monitored the backup job is.

How often should we exercise recovery?+

Often enough that it is unremarkable. Teams that exercise quarterly handle real incidents noticeably better than teams that exercise annually.

Will this satisfy our continuity obligations?+

The evidence is a record of exercises you actually ran, which is stronger than a plan. Where a specific attestation is required, ask us directly.

Other capabilities

Where else this goes

Startups

Start on something that will still be right at a hundred times your size, and pay now what a startup should pay.

Enterprise Migration

Move in stages with the old arrangement still running, and cut over only once the replacement has carried real traffic.

AI & Machine Learning

Get capacity when the experiment is ready, keep what produced a result, and put models in front of users without a separate platform.

Data Platform

Keep everything at full fidelity, query it without a project, and stop deciding today what you will want to ask next year.

Web & Mobile Applications

Ship the application your users touch, on an address that stays put, with every version one click behind you.

Internal Tools

Build the tools your own teams need, at a cost that makes small improvements worth doing.

Start where it matters most

Begin with one workload. Keep what you have running. Decide whether to continue once you have seen it carry something real.

No migration required to begin. Nothing to tear down if you stop.
