# Backup Restore Testing: Prove Recovery Before an Incident

> A successful backup job does not prove that files, databases and keys can be restored. Use a small, repeatable recovery test.

A green backup status confirms that a job finished. Recovery requires more: usable data, available encryption keys, compatible software, correct permissions and a documented order.

## Run a safe restore drill

1. Choose an isolated test location.
2. Restore files and the database from a named recovery point.
3. Supply secrets through the normal secure process.
4. Open representative pages and perform a transaction.
5. Measure elapsed time and missing dependencies.
6. Destroy test copies containing production data.

## Test different failure shapes

A deleted file, corrupted database and lost server may use different recovery paths. Include an offline or separately protected copy so compromised administrator credentials cannot erase every backup.

## Turn results into changes

Record who performed the test, which backup was used and what failed. Recovery confidence comes from evidence repeated on a schedule, not from the presence of an archive.

## Include external dependencies

A restored database may still rely on DNS, object storage, email, license servers and identity providers. Record these dependencies and decide which can be replaced during an outage.

## Protect the drill

Mask personal data where possible, prevent test systems from sending real email and deny public indexing. A recovery exercise should not create a privacy incident or duplicate production actions.

## Define the promise before choosing the tool

Recovery Point Objective describes acceptable data loss; Recovery Time Objective describes acceptable outage duration. A nightly backup cannot meet a one-hour RPO, and a terabyte archive that takes two days to restore cannot meet a four-hour RTO.

## Run a complete isolated restore

Recover files, database, configuration, secrets and external dependencies into a protected environment. Prevent test email and payments, mask personal data where possible, then verify authentication, representative records and application health. Measure time from incident declaration to usable service.

Record failed steps and update the runbook. Encryption, off-site copies and immutability protect stored backups, but only a successful restore demonstrates recoverability.
