“Works like a charm. I've found everything I needed here. Easy to configure and use.”
The 3-2-1 Rule, Automated
Industry best practices for data protection, implemented automatically on every instance you deploy
Three Copies of Your Data
Your live production data, plus local snapshots, plus offsite replicas. Triple redundancy means no single failure can cause data loss.
- Live production instance
- Local NVMe snapshot
- Offsite S3 replica
Two Different Storage Types
Local NVMe snapshots for instant recovery. S3-compatible object storage for durable offsite backup. Different failure modes, maximum protection.
- NVMe SSD (TopoLVM CSI)
- S3 Object Storage
- Independent failure domains
One Copy Offsite
A separate copy on dedicated storage servers in another Falkenstein datacenter building. Protected against host, rack and datacenter-level failures, and against ransomware.
- Separate datacenter building
- Ransomware protection
- Disaster recovery ready
How Your Data Is Protected
From live data to offsite recovery in three automated steps
Live Data
Your production instance running on high-performance NVMe storage
Local Snapshot
TopoLVM CSI snapshot on local NVMe cluster for instant restore
Velero Export
Kubernetes-native backup exports to S3-compatible storage
Offsite S3
Encrypted backup on separate storage servers in another Falkenstein datacenter, retained 30 days
Why Proper Backups Matter
See the difference between hoping for the best and being prepared
What Backups Cover
Snapshots, offsite replication, and point-in-time recovery
Automated Daily Snapshots
Set-and-forget backup scheduling. Every instance is automatically snapshotted daily with no configuration required.
Point-in-Time Recovery
For Managed PostgreSQL, restore to any second within the 30-day retention window. Recover from accidental deletes or corrupted transactions.
S3 Object Storage Replication
Every snapshot is automatically replicated to S3 storage on separate storage servers, using Velero for Kubernetes-native backup.
Instant Local Restore
Local NVMe snapshots restore in seconds. No waiting for downloads from cold storage when you need data fast.
Encrypted at Rest & Transit
AES-256 encryption for stored backups. TLS 1.3 for all data movement. Your backups are as secure as your live data.
Ransomware Protection
Backups live on separate storage servers behind their own credentials, isolated from your instances. Even if your primary infrastructure is compromised, recovery is possible.
Backup Use Cases
From compliance requirements to disaster recovery
Business Continuity
Ensure your business can recover from any disaster. Meet RPO and RTO requirements with automated backups and fast restore capabilities.
- Defined recovery objectives
- Automated failover procedures
- Documented recovery plans
Compliance & Audit
Meet GDPR, SOC 2, and other regulatory requirements with encrypted backups, audit trails, and EU data residency.
- GDPR-compliant storage
- Immutable audit logs
- Data residency controls
Ransomware Recovery
Backups on isolated storage with separate credentials let you recover from ransomware attacks without paying ransom or losing data.
- Isolated storage
- Separate credentials
- Independent recovery path
Development & Testing
Restore production data to staging environments for testing. Create point-in-time copies for development workflows.
- Clone to staging
- Point-in-time copies
- Isolated test environments
Simple Restore Process
Four steps to restore your data, from selection to verification
Select Recovery Point
Choose from available snapshots or specify exact timestamp for point-in-time recovery.
Choose Destination
Restore to existing instance (replace) or create new instance from backup.
Initiate Restore
One-click restore from dashboard or API. Local restores complete in under 2 minutes.
Verify & Resume
Automated integrity checks confirm successful restore. Resume operations immediately.
Encrypted, Verified, and Kept in the EU
Your backups are protected with the same rigor as your live data
AES-256 Encryption
Industry-standard encryption for all backup data at rest
TLS 1.3 In Transit
All data movement encrypted with latest TLS protocol
Integrity Verification
Automated checksum validation on every backup
EU Data Residency
All backups stored within European Union borders
Optimized for Every Service
Each service type has tailored backup strategies for maximum reliability

Backups FAQ
Snapshots, retention, restores.
The 3-2-1 rule is an industry best practice: keep 3 copies of your data, on 2 different storage types, with 1 copy offsite. DanubeData keeps your live data, local NVMe snapshots, and a copy on separate S3-compatible storage servers in another Falkenstein datacenter building.
Sleep Better Knowing Your Data Is Protected
Every DanubeData service includes 3-2-1 compliant backups. No extra fees, no complex configuration. Your data is protected from day one.
