- Restore into an isolated environment.
- Check application behaviour as well as database integrity.
- Measure data age separately from recovery time.
Define what must return
Start with an outcome: which service needs to work, which records must be present and who must be able to use it? “We have a backup” does not answer those questions. A successful copy can still omit a configuration file, depend on an unavailable key or capture an inconsistent database.
Choose a small, isolated recovery target. Do not test your first restore by replacing the production system. A separate temporary environment lets you investigate missing dependencies without turning a rehearsal into an outage.
Make consistency explicit
For a database, use a supported backup mechanism rather than assume copying an open file captures a coherent state. Python’s SQLite interface provides an online backup operation. That operation is the starting point, not the entire recovery procedure. You must still retain the application version and any configuration required to interpret the data.
Keep secrets separate from ordinary source archives. A recovery plan that depends on a password stored next to the data deserves a different security review from a backup that refers to a protected credential store.
Restore, then exercise the service
Open the restored database and check its integrity. Compare a few meaningful records and counts. Then start the matching application version against the restored state and follow the important user journeys. Can a reader find an article? Can an editor see its version history? Are permissions enforced?
A count match can miss damaged relationships. A login page can load while every account is unusable. Pick checks tied to your own service rather than collect green indicators that never touch its essential behaviour.
Measure the recovery honestly
Record when the incident scenario starts, when the copy becomes available, when the restore completes and when functional checks pass. Keep the data age separate from the time needed to recover. A very fast restore of an old backup can still lose more recent work than the organisation can tolerate.
Document obstacles as findings: missing tools, unexpected permissions, absent credentials, unclear ownership. The rehearsal is valuable precisely because it exposes these conditions before a real incident.
Leave a repeatable record
A useful evidence bundle contains the backup checksum, source version, restore steps, integrity results, functional test output and the limits of the exercise. It should be understandable to a colleague who did not watch the test.
Repeat after material changes to the application or storage design. Recovery is not a badge awarded permanently after one demonstration; it is a capability that must stay compatible with the system it protects.
