Most startups do not have a disaster recovery plan. The ones that do often have a document someone wrote six months ago that nobody has read since and nobody has tested. Then a database goes down, an engineer accidentally deletes a production table, or a cloud provider has a regional outage, and the response is pure improvisation.
We have seen companies lose days of customer data because their backups were silently failing. We have watched teams spend 12 hours recovering from an incident that should have taken 30 minutes with a tested plan. The difference between a minor inconvenience and an existential crisis is almost always preparation.
This is a disaster recovery plan designed for startups. It is not a 200 page enterprise document. It is the minimum viable plan that will actually get followed when things go wrong.
Define Your Recovery Objectives
Before anything else, answer two questions:
Recovery Time Objective (RTO): How long can you be down before it causes serious damage? For a consumer app, the answer might be 1 hour. For a B2B SaaS with enterprise clients and SLAs, it might be 15 minutes. For an internal tool, it might be 4 hours.
Recovery Point Objective (RPO): How much data can you afford to lose? If your RPO is zero, you need real time replication. If your RPO is 1 hour, hourly backups suffice. If your RPO is 24 hours, daily backups work. Most startups land between 1 hour and 15 minutes for RPO.
Write these numbers down. Every decision in your disaster recovery plan flows from them. An RTO of 15 minutes requires fundamentally different infrastructure than an RTO of 4 hours, and the cost difference is significant.
The Minimum Viable Backup Strategy
Database Backups
At minimum, you need automated daily backups stored in a different region from your production database. For most startups on Supabase or AWS RDS, this is a configuration setting, not an engineering project.
Daily automated backups as the baseline. If your RPO requires it, increase frequency to hourly or enable continuous archiving (point in time recovery). Postgres supports WAL archiving for point in time recovery to any second within your retention window.
Store backups in a separate region. If your production database is in us-east-1, store backups in us-west-2. A regional outage that takes down your database and your backups in the same region is not a hypothetical scenario. AWS has had region scoped outages that lasted hours.
Encrypt backups at rest. Use your cloud provider's managed encryption. Unencrypted backups are a data breach waiting to happen, particularly for products subject to GDPR or HIPAA.
Test your restores. This is the step that everyone skips and everyone regrets skipping. Schedule a monthly restore test. Spin up a temporary database, restore the latest backup, and verify the data is intact and the application can connect to it. Automate this if possible. An untested backup has unknown reliability, and you do not want to discover reliability issues during an actual disaster.
File and Object Storage
If your application stores user uploaded files (images, documents, videos), those need backup too. S3 and similar object storage services are highly durable (99.999999999% durability for S3), but accidental deletion, misconfigured lifecycle policies, and malicious actors can still wipe data.
Enable versioning on your storage buckets. This protects against accidental overwrites and deletions.
Enable cross region replication if your RPO requires it. This adds cost but provides geographic redundancy.
Application Configuration and Infrastructure as Code
Your application code is in version control. But is your infrastructure? If your server went down right now, could you recreate the exact environment from scratch?
Infrastructure as Code (IaC) using tools like Terraform, Pulumi, or CloudFormation ensures that your entire infrastructure, servers, load balancers, databases, DNS, security groups, is defined in code and can be recreated in minutes rather than hours of manual clicking in a console.
Store IaC in version control alongside your application code. When disaster strikes, you should be able to run a single command to recreate your infrastructure.
Incident Response Playbook
A disaster recovery plan without a response procedure is just a list of good intentions. You need a playbook that someone can follow at 3 AM while stressed and under slept.
The On Call Rotation
Someone needs to be responsible for responding to incidents at any given time. For a small team, this might be a rotation between 2 to 3 engineers. The on call person should have:
- Access to all production systems
- Authority to make decisions (roll back, failover, page additional team members)
- Notification setup that will actually wake them up (PagerDuty, Opsgenie, or at minimum a phone call, not a Slack message)
The Incident Severity Levels
Severity 1 (Critical): Production is down for all users. Data loss is occurring. Revenue impact is immediate. Response: all hands, immediate.
Severity 2 (Major): Significant degradation. A major feature is broken or a subset of users cannot access the product. Response: on call engineer plus one additional, within 15 minutes.
Severity 3 (Minor): Cosmetic issue or minor feature broken. No data loss. Limited user impact. Response: next business day.
The Response Checklist
When a Severity 1 or 2 incident occurs:
1. Acknowledge the incident within 5 minutes. Confirm someone is actively responding.
2. Assess the scope. What is broken? How many users are affected? Is data loss occurring?
3. Communicate to stakeholders. Post a status update. If you have a status page, update it. If you have enterprise clients, notify them proactively.
4. Mitigate the immediate impact. This often means rolling back the last deployment, failing over to a backup, or scaling up resources. The goal is to stop the bleeding, not find the root cause.
5. Resolve the underlying issue. Once the immediate impact is mitigated, diagnose and fix the root cause.
6. Post mortem. Within 48 hours, document what happened, why it happened, what the impact was, and what you are doing to prevent it from happening again. No blame. Just facts and action items.
The Specific Scenarios You Should Plan For
Scenario 1: Database Corruption or Accidental Deletion
An engineer runs a DELETE without a WHERE clause. A migration goes wrong and corrupts a table. A bug in the application writes invalid data at scale.
Response: Restore from the most recent backup. If you have point in time recovery, restore to the moment before the incident. If you only have daily backups, you lose up to 24 hours of data. This is why your RPO matters.
Scenario 2: Cloud Provider Outage
Your primary region goes down. This happens more often than cloud providers would like to admit. AWS, GCP, and Azure have all had multi hour regional outages in the past 2 years.
Response for most startups: Wait it out. Regional outages typically resolve in 1 to 4 hours, and the cost of maintaining a hot standby in another region is significant. If your RTO is less than 1 hour, you need multi region deployment with automated failover, and that is a meaningful infrastructure investment.
Response for critical applications: Automated failover to a secondary region. This requires multi region database replication, DNS failover (Route 53 health checks or equivalent), and application deployments in both regions.
Scenario 3: Security Breach
An attacker gains access to your systems. This could be through a compromised credential, an unpatched vulnerability, or a supply chain attack.
Response: Contain first. Revoke compromised credentials, isolate affected systems, and block the attack vector. Then assess what data was accessed. Then notify affected users and regulators as required by law (GDPR requires notification within 72 hours). Our web app security checklist covers the preventive controls that reduce the likelihood of this scenario.
Scenario 4: Deployment Gone Wrong
The new version has a critical bug that was not caught in testing. Users are seeing errors, data is being written incorrectly, or the application is crashing.
Response: Roll back immediately. This is why zero downtime deployment strategies with instant rollback capability matter. If you can roll back in 30 seconds, a bad deployment is a minor blip. If rolling back takes 20 minutes of manual work, it is a significant incident.
What This Costs
A basic disaster recovery setup (automated backups, cross region storage, a documented runbook) costs almost nothing beyond the infrastructure you are already paying for. The time investment is 2 to 3 days to set up backups, write the runbook, and test a restore.
A robust setup with multi region failover, automated health checks, and infrastructure as code adds 1 to 2 weeks of engineering time and increases your monthly infrastructure costs by 30 to 60 percent for the secondary region.
For most startups, we recommend the basic setup immediately and the robust setup once you have paying customers with SLA expectations. The important thing is to have something, because the difference between "basic plan" and "no plan" is the difference between a recoverable incident and a company ending one.
Our ongoing management service includes disaster recovery planning, backup monitoring, and regular restore testing. If your current plan is "we will figure it out when it happens," that is not a plan.
