Quick answer: A disaster recovery plan is a written, tested procedure answering four questions: what can fail, what must come back first, how exactly do we restore it, and how long will that take. For a typical VPS setup it fits on two pages — write it before you need it and rehearse it once a quarter.
Overview
When a server dies at 3 a.m., nobody thinks clearly. A DR plan moves the thinking to a calm afternoon: inventory, priorities, step-by-step restore instructions, credentials location, and measured recovery times (RTO) against acceptable data loss (RPO). Backups are the raw material; the plan is what turns them into recovery.
Before you start
- Working, tested backups (integrity testing) — a plan on top of untested backups is fiction.
- An inventory: servers, services on each, data locations, dependencies (DNS, mail, payment webhooks).
- Agreed targets per service: RPO (max data loss) and RTO (max downtime).
Step-by-step guide
- Inventory and rank: list every service, then order by business impact — usually database and site first, analytics last.
- Define scenarios: single-service failure, full-server loss, compromise (restore to a new server — see compromised server), regional outage.
- Write the runbook per scenario: exact commands, in order, with paths and hostnames — the restore guide is your template. Assume the person executing is stressed and knows less than you do today.
- Store access safely: the plan, backup locations and credentials must be reachable when the primary server is not — a password manager plus a printed copy beats a note on the dead machine.
- Rehearse: quarterly, restore to a scratch VPS by following the runbook literally; fix every step where you had to improvise, and record the real RTO.
Common issues
- The plan lives on the server it protects: keep copies offsite — the irony writes itself.
- Uncounted dependencies: the site is up but DNS TTLs, SSL certs or webhook IPs still point at the corpse; put them in the runbook.
- Untested heroics: a plan that has never been rehearsed takes 5× longer under pressure — the drill is the plan.

Frequently asked questions
What must a small-team DR plan contain?
An inventory of services ranked by importance, restore runbooks with exact commands, the location of backups and credentials, and measured recovery times from a real rehearsal.
What are RTO and RPO in a disaster recovery plan?
RTO is how long recovery may take (downtime tolerance); RPO is how much recent data you may lose. Together they dictate backup frequency, retention and the infrastructure you keep ready.
Where should the DR plan itself be stored?
Anywhere that survives losing your servers: a password manager, an offsite document store, even a printed copy. A plan stored only on the machine it protects is a punchline.
