Protecting Personally Identifiable Information (PII) and Personal Health Information (PHI) isn’t a one-time task — it has to hold at every moment a record exists. That is the idea behind Continuous Data Protection (CDP): instead of relying on the occasional backup, you protect data continuously, so you can always recover a clean, recent state.

Classic CDP is an infrastructure technique — it journals every change to your storage so you can roll a whole system back to almost any point in time. That is invaluable for disaster recovery, but it is blind to the questions that matter most for sensitive records: who changed this customer’s data, when, and can I put one field back without restoring the entire database? For PII and PHI you need continuous protection at the record level too.

What Continuous Data Protection means

CDP goes beyond traditional periodic backups by capturing changes in real time or near-real time. Its hallmarks:

• Point-in-time recovery — restore to almost any moment, not just last night’s snapshot.
• Minimal data loss — changes are captured as they happen, driving Recovery Point Objective (RPO) toward zero.
• Fast restoration — lower Recovery Time Objective (RTO) and less downtime.

Infrastructure CDP delivers this for whole systems. Databunker adds the same philosophy to the individual records that carry your most sensitive data.

Continuous protection at the record level with Databunker Pro

Databunker Pro keeps PII and PHI protected continuously, not just backed up periodically:

• Always encrypted. Records are stored with per-record AES-256 encryption, so protection is the default — there is no window where the data sits in plaintext.
• Every change is versioned. Each create or update keeps an immutable, integrity-checked version of the record, with the values before and after the change. You can fetch any earlier version and roll a single record back — without touching the rest of your database.
• Every change is audited. A tamper-evident audit trail records who accessed or modified a record, when, and why — usable as evidence in an investigation or audit.
• Access is controlled. Conditional role-based access control (CRBAC) and gated bulk operations limit who can change records in the first place.

Together these give each record its own recoverable, audited history — continuous protection at the row level, not just the disk.

const DatabunkerproAPI = require('databunkerpro-js');

const api = new DatabunkerproAPI(
  process.env.DATABUNKERPRO_URL,
  process.env.DATABUNKERPRO_TOKEN
);

// List every saved version of a record
const versions = await api.listUserVersions('email', 'john@example.com');

// Fetch an earlier version — a point-in-time view of the record
const previous = await api.getUser('email', 'john@example.com', 2);

// Roll the record back by re-applying that version
await api.updateUser('email', 'john@example.com', previous.profile);

// See who changed the record, when, and why
const audit = await api.listUserAuditEvents('email', 'john@example.com');

Why it matters

• Undo mistakes. A bad migration or an accidental overwrite of a customer profile is one version away from being reversed.
• Investigate with confidence. When a field looks wrong, the audit trail shows exactly who changed it — a direct answer to insider-threat questions. See trace profile access and change.
• Avoid the backup-restore trap. Restoring an old system backup can quietly resurrect a user who exercised their right to erasure. When the vault is the source of truth, deletion sticks — see the GDPR user request workflow.
• Produce compliance evidence. Versioned, tamper-evident records support GDPR’s accuracy and integrity principles and HIPAA audit controls.

It complements your backups, not replaces them

To be clear: Databunker is not a backup or disaster-recovery system, and it doesn’t replace Veeam, your database snapshots, or storage-level CDP. It is the PII-aware layer on top — continuous protection, history, and accountability for the specific records that regulators and attackers care about most. Keep both.

Summary

Continuous Data Protection keeps data recoverable at every moment. Databunker Pro brings that to your most sensitive records: always encrypted, every change versioned and audited, every access controlled. Pair it with your existing backups and your PII and PHI stay protected continuously — and provably.

Frequently asked questions

Is Databunker a backup system? No. It continuously protects the records themselves — encryption, versioning, and audit — and complements your infrastructure backups rather than replacing them.

Can I restore a single PII record to a previous state? Yes. Every change is versioned, so you can fetch an earlier version and re-apply it without restoring the whole database.

Is the change history tamper-evident? Yes — versions are immutable and integrity-checked, and the audit trail records who changed what and when.

Does this help with GDPR and HIPAA? It supports GDPR’s accuracy and integrity principles and HIPAA’s audit-control requirements with a verifiable record history.
