Data loss is not just an IT failure. Under GDPR, it can be a legal disaster. It’s the kind of event that fuels sleepless nights, internal post-mortems, and mandatory breach notifications. The regulation is clear: personal data must be protected. If it’s lost, compromised, or accessed without authorization, the clock starts ticking. You have 72 hours to report it, detail the scope, and explain the measures taken to contain the damage. Fail to do this, and the fines — up to €20 million or 4% of annual revenue — will hurt more than the breach itself.
GDPR treats data loss and data breaches with equal seriousness. Data loss isn’t always a cyberattack; it can be accidental deletion, system failure, or corruption. If it impacts personal information, it falls under GDPR’s definition of a breach. Backups, encryption, and redundancy are no longer “nice to have.” They are compliance requirements, proof that you planned for failure before it happened.
The engineering challenge is twofold: preventing data loss and proving you’ve done everything to mitigate it. Real-time monitoring, immutable backups, and detailed audit logs are no longer optional. Encryption at rest and in transit is table stakes. Access controls must be enforced at the system level. Testing disaster recovery procedures is as critical as deploying code. What’s logged matters. What’s restored matters more.
