GDPR-Compliant Backup: Data Protection and Recoverability without Compromise
GDPR Art. 32 requires technical measures for data restoration after incidents. A backup system that cannot prove this capability is worthless from a compliance perspective.
Many companies have backups, but few have backups that are GDPR-compliant and actually tested. Art. 32 GDPR requires the ability to quickly restore availability and access to personal data in the event of a physical or technical incident. This means: not just having a backup, but proving that the restore works.
The most common challenges
Backups exist, but restores were never tested
A backup that has never been restored is a hope, not a guarantee. Many companies discover during their first real restore need that data is corrupt, outdated, or incomplete.
GDPR requires deletion concepts even for backup data
If a customer requests data deletion, this data must also be removed from backups, or the backup cycle must be designed so that deleted data persists only for a defined period.
Backup data is unencrypted or not access-secured
An unencrypted backup is a security vulnerability. If the backup medium is compromised, all personal data within is exposed, triggering GDPR reporting obligations.
The CCsolutions approach
CCsolutions implements backup strategies designed for GDPR compliance from day one: AES-256 encryption of all backup data at-rest and in-transit, role-based recovery (RBAC), and backup policies that consider retention cycles for deletion requests.
Restore tests are not an optional add-on but a core part of the operational concept: automated monthly restore tests, documented RTO/RPO measurements, and alerts if a test fails. The audit log shows exactly when the last successful restore occurred.
All backups and restore tests are documented: who backed up what and when, when the last test occurred, and which RTO/RPO targets were achieved. This documentation is audit-ready and accessible for regulators on request.

Frequently asked questions
How long must backups be kept under GDPR?
GDPR does not prescribe fixed retention periods, but they must be justifiable and documented. Commercial and tax laws (6-10 years) may dictate minimum storage times.
What happens if a customer requests deletion while their data is still in backups?
The correct approach depends on the strategy: granular deletion (complex), shortened rotation cycles, or pseudonymization. CCsolutions implements the strategy that fits your context.
How often should restore tests be performed?
At least monthly for critical systems, quarterly for non-critical. The key is not just frequency, but that tests are documented and monitored for anomalies.
