The difference between 'running' and 'working'
A common failure in data governance is confusing a successful backup log with a successful recovery strategy. A backup job might return a "success" status every night for a year, yet the data inside could be corrupted, incomplete, or technically incompatible with the current system due to schema changes.
To demonstrate that a policy works, you must validate the output, not just the input. This means regularly testing the restoration process to prove three things:
- Integrity: The data is readable and uncorrupted.
- Completeness: Relationships between records (e.g., contacts associated with deals) remain intact.
- Timeliness: The restoration meets the Recovery Time Objective (RTO) defined in your service level agreement.
1. Designing the test scenario
Testing should not be random. It should simulate specific failure modes documented in your risk register.
- The "Fat Finger" Test: Simulate the accidental deletion of a single critical record or a small batch of records. Can you locate and restore just those specific items without rolling back the entire database?
- The "Corruption" Test: Simulate a scenario where a workflow or integration has overwritten a field with bad data across thousands of records. Can you identify the exact point in time before the error occurred?
- The "Catastrophe" Test: Simulate a total loss of data for a specific object. Can you rebuild the dataset from the archive?
2. The importance of a sandbox
Never test a restoration policy in your live production environment unless you are recovering from an actual disaster. Overwriting live data to prove you can restore old data is a risk you do not need to take.
A robust testing process involves restoring data to a sandbox or a segregated staging area. This allows you to verify the data structure and content without disrupting business operations. It proves that the data can be put back, without the danger of actually putting it back into the live workflow until absolutely necessary.
3. Documenting the evidence
For compliance standards like ISO 27001 or SOC 2, the test itself is not enough; you need the paperwork.
Your restoration test log should record:
- Date and time of the test.
- Scenario tested (e.g., "Restore 50 contacts from 30 days ago").
- Time taken to complete the restore (to validate RTO).
- Validation result (e.g., "Pass: Records matched source").
- Tester signature.
This log transforms your backup strategy from a theoretical assumption into a verified control.
4. How backHUB supports validation
At Struto, we use backHUB to facilitate this validation. backHUB provides robust backup and rapid point-in-time restore for HubSpot data. Because it allows for granular recovery, you can easily run test restores of specific datasets to verify integrity.
It is designed to ensure data safety even when system changes occur. Its comprehensive change tracking supports the validation process, allowing you to prove exactly what version of the data you are restoring. This makes the periodic testing of your retention policy a manageable operational task rather than a complex engineering project.
The verdict
A backup you haven't tested is a backup you don't have. Regular restoration tests are the only way to guarantee that your safety net will hold when you fall.
