A medical research facility is concerned that some backup archives may have been changed during a recent security event. They want confidence that the backup data remains valid. Which procedure increases confidence that the backups have not been altered?
Generate cryptographic sums for all backup archives and compare them to known baselines
Perform routine manual checks of file sizes and names in backup containers
Rely on the backup application’s timestamps to verify that files are intact
Create a new snapshot of the production data and confirm it boots without errors
Comparing cryptographic sums of backup archives to their reference values is a reliable way to detect if data has been manipulated. A sum is generated from an unaltered baseline, then compared with a sum made of the backup file. If alterations have occurred, the sums will differ. Checking timestamps or file sizes might indicate changes but will not fully confirm content validity. Simply booting a snapshot may confirm the system’s functionality but may not reveal if data was changed in a less obvious way.
