Explanation

Regularly testing backups verifies that data can actually be restored when needed - a backup that has never been tested may be corrupt, incomplete, or use an unreadable format. Annual backups are insufficient since data changes constantly and a year of work could be lost. Storing backups on the same device as the original defeats the purpose entirely, as a hardware failure or ransomware attack would destroy both. Testing is the cornerstone of any reliable backup strategy.
