What is one potential drawback of enabling encryption at rest?

Enabling encryption at rest provides a vital layer of security for protecting sensitive data stored within a system or database. However, one potential drawback is that it can complicate backup processes. When data is encrypted, the encryption keys need to be managed carefully to ensure that the backups can be restored successfully. This adds an additional step in backup and restoration workflows, potentially requiring specialized procedures or tools to handle the encrypted data appropriately.

Furthermore, if backups are not encrypted or if there's a failure in managing encryption keys, restoring data from backups can become challenging and may lead to data loss. Therefore, while encryption enhances security, it does introduce complexities in backup strategies and operational procedures that must be adequately addressed. This consideration helps organizations to balance security needs with operational efficiency effectively.
