Backup, Restore, and Drill Practice: A SaaS Disaster Recovery Guide

What you actually need to know

• The plan is small. Three documents, two automated processes, one quarterly drill.
• RTO and RPO are commitments. Pick them deliberately and measure against them.
• Backups live in a different account or region from the primary.
• The drill is what proves the plan is real.
• Multi region is a different problem from backup and restore.

The core argument

A SaaS disaster recovery plan is one of the simplest pieces of operational infrastructure to build well and one of the most commonly underbuilt. The reason is psychological. The work pays off only when something goes wrong. Founders who have not yet been through a real recovery event assume the backups they have are sufficient. Founders who have been through one always invest more in drills than they did before.

The plan does not need to be long. The teams that recover well do not have hundreds of pages of documentation. They have a clear inventory of what is backed up, a runbook that any senior engineer can execute, and a drill schedule with results. The documentation is shorter than most product specs. The discipline is what makes the difference.

The plan does need to be specific. Vague commitments to recovery do not survive contact with a real incident. A specific RTO of four hours with a specific RPO of fifteen minutes gives the team a target to design against. The plan should commit to numbers that are achievable and meaningful.

The plan also needs to acknowledge what is not in scope. A SaaS that targets a four hour RTO is not promising the same recovery during a regional cloud provider outage as during a database corruption. The plan should be honest about which scenarios it covers.

What to back up

How much does this cost

For a B2B SaaS at modest scale, the all in cost of a good disaster recovery setup is 100 to 500 USD per month in cloud storage and replication fees, plus four to twelve engineering hours per quarter for drills. The cost rises with retention and replication choices but is small compared to the value of being able to recover.

For products with significant compliance scope, expect 500 to 3000 USD per month for the same setup with longer retention, encrypted backup vaults, and more frequent drills. The marginal cost above the basic setup buys defensible compliance posture for enterprise customers.

Features the plan must have

• A named owner for the plan and for each drill.
• A backup inventory in version control.
• A restore runbook in version control.
• Automated backup verification that fails loudly.
• Cross account or cross region backup storage.
• Documented RTO and RPO with measurement.
• A quarterly drill schedule with results stored.
• A trust portal entry that customers can reference.

Expert opinion

Most disaster recovery work is invisible until it is not. The teams that take it seriously are not paranoid. They are the ones who have been through one real recovery and decided never to do it without practice again. The cost of the plan is small. The cost of operating without one is the kind of bill you do not get to negotiate.

How this played out on a real project

A SaaS client experienced a database corruption caused by a poorly tested migration. The corruption was discovered eighteen hours after the migration ran. The team had backups but had never done a full restore drill.

The recovery took seventy two hours. The team had to figure out the runbook in real time. They lost roughly six hours of customer data because the most recent clean point in time recovery available was older than expected. Two enterprise customers churned over the incident.

After the incident, we built the disaster recovery plan together. Three documents. Quarterly drills. Cross account backup. The next drill ran in six hours. The drill after that in four. The next real incident, six months later, was a smaller corruption with a four hour recovery and no customer churn.

Common mistakes teams make

1. Backups in the same account as the primary.
2. No verification that the backup is restorable.
3. No drill schedule. Backups untested for years.
4. Vague RTO and RPO commitments.
5. Database backed up but configuration, secrets, and files forgotten.
6. Retention that does not match compliance requirements.
7. Single person responsibility for recovery.
8. No trust portal evidence. The work happened but cannot be proven to customers.

A 30 day plan to put disaster recovery in place

1. Week one. Build the backup inventory. Identify what is backed up and what is not.
2. Week two. Fix the gaps. Add the missing backups. Move to cross account storage.
3. Week three. Write the restore runbook. Document the RTO and RPO commitments.
4. Week four. Run the first drill. Measure. Retrospect. Schedule the cadence.
