Quick answer
To test whether your business can restore data, define recovery objectives for each system, including how much data loss is acceptable and how quickly service must return, confirm what is backed up and where, keep at least one copy isolated from production, then perform scheduled test restores to a separate environment, verify the restored data and record how long recovery took.
Key takeaways
- Define acceptable data loss and downtime per system.
- Keep at least one backup copy isolated from production.
- Test restores regularly and measure recovery time.
- Document recovery steps so more than one person can follow them.
Who this guide is for
Business owners, IT managers and operations leaders responsible for business applications, databases and files.
Set recovery objectives
For each important system, agree how much data you can afford to lose, called the recovery point objective, and how quickly the system must be usable again, called the recovery time objective. An order system may need minimal data loss and quick recovery; an archive may tolerate days. These objectives determine backup frequency and recovery design.
Inventory what must be backed up
Include databases, uploaded files, configuration, source code, infrastructure definitions, encryption keys and credentials stored securely. Cloud software-as-a-service tools may need their own exports. Missing configuration or keys can make backups unusable, so check the whole recovery chain. Map each system to its backups in a simple table with location, frequency, retention and owner, and keep it current. Include third-party services such as email marketing or CRM tools that hold business data outside your own servers.
Protect backups from the same disaster
Backups stored on the same server or account as production can be lost in the same incident, such as ransomware, accidental deletion or account compromise. Keep copies in a separate location or account, with restricted access and, where available, immutable or versioned storage. A widely used guideline is multiple copies on different media with one off-site.
Test restores regularly
Schedule test restores, for example quarterly for critical systems, into a separate environment. Restore the database and files, start the application and verify that data is complete and usable. Measure how long each step takes and compare it with your recovery time objective. Record each test result, including problems found and fixes made, so you have evidence of recovery capability for audits and insurers.
Verify data integrity
A restore that completes without errors may still contain corrupted or incomplete data. Check record counts, recent transactions and key reports against expectations. For financial systems, compare balances. Automated integrity checks can supplement manual verification. Involve a business user who knows what the data should look like; they will notice missing or odd records that technical checks may miss. Record what was checked and the result, so the next test can follow the same steps and compare outcomes.
Document and practise the procedure
Write step-by-step recovery instructions, including where backups are, how to access them, required credentials, order of restoration and who to contact. Ensure more than one person can follow them. Practice exercises reveal missing steps before a real incident does. Store the instructions somewhere that remains accessible during an outage, not only on the system being recovered. Update them after every test so they reflect the current setup.
Review after changes
New systems, changed architecture, new data stores and provider changes can break backup coverage. Review the backup inventory whenever systems change. A recovery review typically covers objectives, inventory, isolation, restore tests, integrity checks and documentation, with gaps prioritized by business impact. Add a backup check to your change process, so every new system or data store is covered before it goes into production use.
Scope checklist
- What data loss and downtime are acceptable per system?
- Is everything needed for recovery backed up?
- Is at least one copy isolated from production?
- When was the last successful test restore?
- Can more than one person perform recovery?
Frequently asked questions
What is the difference between RPO and RTO?
Recovery point objective is how much data loss is acceptable, measured in time. Recovery time objective is how quickly a system must be restored after an incident.
How often should backups be tested?
Critical systems should be test-restored regularly, such as quarterly, and after major changes. Frequency depends on risk and change rate.
Are cloud services like Google Workspace backed up automatically?
Providers protect their infrastructure, but accidental deletion or account compromise may still affect your data. Review retention features and consider separate backups.
