Restore a test file without overwriting the working copy

Choose a file with a known expected result

A restore test is strongest when you know what the file should contain. Create a small harmless document with a date and a distinctive sentence, back it up through the normal process and keep a note of its expected content. Do not use a patient record or confidential customer document merely because it is easy to find.

The aim is to verify the backup route. A test that only opens the current working file does not establish that any backup is recoverable.

Perform a non-destructive restore

1. Confirm which backup job and snapshot contain the test file. Record the job status, date and any warning that could affect the selected recovery point.
2. Sign in through the genuine recovery interface using an authorised account. Choose a separate empty destination instead of overwriting the working copy.
3. Restore the selected version using the product's supported procedure. Record start and finish times, including any time spent locating credentials or waiting for download.
4. Open the restored file with the normal application and compare the expected contents. Check whether its name, encoding and required permissions are usable for the intended owner.

Verify the relevant properties

If byte-identical recovery matters, compare hashes of the appropriate original version and restored file. A hash mismatch can be meaningful, but only if both files are meant to represent exactly the same version. A document edited after the backup naturally differs from its older recovery point.

Record the scope honestly

A successful file restore proves something useful about that file, snapshot and access path. It does not prove that the entire operating system can boot, that an application database is consistent or that every retained snapshot is valid. Keep those as separate recovery tests.

Clean up safely

Remove the temporary restored copy through the normal data-handling process when the evidence record is complete. Retain only the minimum proof needed. Do not delete the backup snapshot simply because the test succeeded; it may still be part of the agreed retention schedule.

Repeat at a sensible interval

Test after changing backup credentials, destinations, encryption settings or the protected application. Assign an owner to the next review. A recoverability record should identify the tested path and actual result, not merely repeat the backup application's green status indicator.
