Backup jobs succeed, but the team does not know whether restoration meets the SLA.
Test restoration without damaging production data.
Which operational practice is most appropriate?
Periodically restore into an isolated test environment and measure recovery time and data consistency.
Detailed explanation
File existence does not prove that the restore procedure works or meets the recovery time.

Foundation review
Evidence of recoverability
A successful backup is not evidence that a restore will succeed under outage conditions.
Measured procedure
Timing the end-to-end process exposes gaps in permissions, capacity, or runbooks.
