Backed up is not the same as recoverable
The backup finished. The dashboard shows a green tick. You close the laptop and go home. But what if that green tick is lying to you? It sounds dramatic. It is not. Across organisations of every size, backups complete successfully every night while quietly storing corrupted data, broken recovery chains, or in the worst cases, malware that hitched a ride before the snapshot was taken. Nobody knows. Nothing alerts. The tick stays green. The problem only surfaces the moment you need the backup most.
