What to Back Up
| Component | Contains | Priority |
|---|
| PostgreSQL | All verification data, sessions, AML results, users, settings | Critical |
| MinIO / Storage | KYC documents, selfies, ID photos, address proofs | Critical |
.env file | Configuration, license key, passwords | Critical |
| Redis | Cache and queue state (ephemeral) | Low |
Database Backup
Manual Backup
docker compose exec postgres pg_dump -U verilock verilock > backup-$(date +%Y%m%d-%H%M%S).sql
Compressed Backup
docker compose exec postgres pg_dump -U verilock verilock | gzip > backup-$(date +%Y%m%d).sql.gz
Automated Daily Backup
Create a cron job on the host:
Add:
0 2 * * * cd /path/to/verilock && docker compose exec -T postgres pg_dump -U verilock verilock | gzip > /backups/verilock-$(date +\%Y\%m\%d).sql.gz
Document Storage Backup
MinIO to Local
# Install mc (MinIO client) on host
docker compose exec minio mc mirror local/verilock-documents /tmp/backup-documents
# Copy from container
docker compose cp minio:/tmp/backup-documents ./backup-documents
MinIO to S3
docker compose exec minio mc alias set aws https://s3.amazonaws.com YOUR_KEY YOUR_SECRET
docker compose exec minio mc mirror local/verilock-documents aws/your-backup-bucket/verilock/
Restore
Database
# Stop the app (prevent writes during restore)
docker compose stop app
# Restore
cat backup-20260317.sql | docker compose exec -T postgres psql -U verilock -d verilock
# Or from gzip
gunzip -c backup-20260317.sql.gz | docker compose exec -T postgres psql -U verilock -d verilock
# Restart
docker compose start app
Documents
docker compose cp ./backup-documents minio:/data/verilock-documents
docker compose restart minio
Disaster Recovery
For full disaster recovery, maintain offsite copies of:
- Database dump (daily)
- Document storage (daily or real-time sync)
.env file (after any config change)docker-compose.yml (after any modification)
Store backups in a different location than your deployment. Use encrypted storage for backups containing PII.
