Mitigating the "fat-finger delete" with Queryable Backups, available in MongoDB OpsManager 3.6+ and MongoDB Atlas, allows database administrators to connect to a backup snapshot from within the management UI, eliminating the need for hardware-based restores. This feature enables users to query for deleted data without having to download and install additional software or manually obtain server certificates. By connecting directly to the backup, users can retrieve their lost data more efficiently, reducing the time and cost associated with large-scale restore operations.
