An administrator is responsible for backing up a critical application server. The backup software supports test restores, checksum verification, and log review. The administrator wants to implement a backup validation strategy that provides the highest confidence that the backups are restorable. Which approach should the administrator use?

Compare checksums of the backup files against the original source files.

Verify that the backup media is stored in a secure, offsite location.

Review the backup logs daily to ensure all jobs completed without errors.

Perform a test restore of the backup to an isolated environment and run application-level integrity checks.

How does a checksum help detect errors in a backup file?

It reveals if the data has changed

It identifies the exact location of the error

It compares the file size to the original

It repairs corrupted data automatically

What is the primary purpose of using a hash function such as SHA-256 in a backup process?

To generate a unique fingerprint of the data

To index the backup for faster retrieval

A backup administrator is configuring a backup system that stores data on a RAID array. The administrator wants to protect against silent data corruption that might not be detected by the RAID controller. Which additional measure should the administrator implement?

Rely on the RAID array's parity to detect and correct all errors.

Use a different RAID level, such as RAID 10.

Enable end-to-end checksum verification on the backup software.

Increase the frequency of full backups.

During a backup verification process, what does comparing a file's checksum before and after the backup confirm?

The file's permissions are preserved

The file is stored in the correct folder

The file's content has not changed
