What is the primary action an administrator can take to ensure that backups can be restored without data loss?

Testing for data integrity is essential to ensure that backups can be restored without data loss. This process involves verifying that the data in the backup matches the original data, ensuring that no corruption or degradation has occurred during the backup process or while stored. If the data integrity check reveals discrepancies, it indicates that the backup may not be reliable, allowing the administrator to address issues before an actual data recovery situation occurs. This proactive approach is critical for maintaining the reliability of backup systems and ensuring that recovered data is complete and accurate.

While scheduling backups frequently helps to minimize potential data loss by ensuring more recent data is backed up regularly, it does not guarantee that the backups are functional or free of corruption. Similarly, increasing storage capacity does not address the quality or integrity of the data being backed up. Logging all access attempts may be beneficial for security auditing but does not directly contribute to the restoration quality of backups. Thus, verifying data integrity stands out as the most crucial action for ensuring reliable restores.
