# Database Backup Strategy
|
||||
|
||||
## Overview
|
||||
|
||||
The Maternal App implements a comprehensive automated backup strategy to ensure data protection and business continuity.
|
||||
|
||||
## Features
|
||||
|
||||
### 1. Automated Backups
|
||||
- **Schedule**: Daily at 2 AM (configurable via `BACKUP_SCHEDULE`)
|
||||
- **Databases**: PostgreSQL (primary) + MongoDB (AI chat history)
|
||||
- **Compression**: Gzip compression for storage efficiency
|
||||
- **Retention**: 30 days (configurable via `BACKUP_RETENTION_DAYS`)
|
||||
|
||||
### 2. Storage Options
|
||||
- **Local**: `/var/backups/maternal-app` (development/staging)
|
||||
- **S3**: AWS S3 for production (off-site storage)
|
||||
- Encryption: AES256
|
||||
- Storage Class: STANDARD_IA (Infrequent Access)
|
||||
|
||||
### 3. Manual Operations
|
||||
- Manual backup triggering
|
||||
- Backup listing
|
||||
- Database restoration
|
||||
- Admin-only access
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
```bash
|
||||
# Enable/disable backups
|
||||
BACKUP_ENABLED=true
|
||||
|
||||
# Backup schedule (cron format)
|
||||
BACKUP_SCHEDULE=0 2 * * *
|
||||
|
||||
# Retention period (days)
|
||||
BACKUP_RETENTION_DAYS=30
|
||||
|
||||
# Local backup directory
|
||||
BACKUP_DIR=/var/backups/maternal-app
|
||||
|
||||
# S3 configuration (optional)
|
||||
BACKUP_S3_BUCKET=maternal-production-backups
|
||||
BACKUP_S3_REGION=us-east-1
|
||||
BACKUP_S3_ACCESS_KEY=your-access-key
|
||||
BACKUP_S3_SECRET_KEY=your-secret-key
|
||||
```
|
||||
|
||||
### Required Packages
|
||||
|
||||
```bash
|
||||
# PostgreSQL client tools
|
||||
sudo apt-get install postgresql-client
|
||||
|
||||
# MongoDB tools
|
||||
sudo apt-get install mongodb-database-tools
|
||||
|
||||
# AWS SDK (for S3 uploads)
|
||||
npm install @aws-sdk/client-s3
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Automated Backups
|
||||
|
||||
Backups run automatically based on the configured schedule. No manual intervention required.
|
||||
|
||||
### Manual Backup
|
||||
|
||||
**Endpoint**: `POST /api/v1/backups`
|
||||
|
||||
**Authentication**: Admin JWT token required
|
||||
|
||||
```bash
|
||||
curl -X POST https://api.maternal-app.com/api/v1/backups \
|
||||
-H "Authorization: Bearer YOUR_ADMIN_TOKEN"
|
||||
```
|
||||
|
||||
**Response**:
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"message": "Backup completed successfully",
|
||||
"data": {
|
||||
"postgres": "/var/backups/maternal-app/postgresql_maternal_app_2025-10-03T02-00-00.sql.gz",
|
||||
"mongodb": "/var/backups/maternal-app/mongodb_2025-10-03T02-00-00.tar.gz",
|
||||
"timestamp": "2025-10-03T02:00:00.000Z"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### List Backups
|
||||
|
||||
**Endpoint**: `GET /api/v1/backups`
|
||||
|
||||
```bash
|
||||
curl https://api.maternal-app.com/api/v1/backups \
|
||||
-H "Authorization: Bearer YOUR_ADMIN_TOKEN"
|
||||
```
|
||||
|
||||
**Response**:
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": {
|
||||
"backups": [
|
||||
{
|
||||
"filename": "postgresql_maternal_app_2025-10-03T02-00-00.sql.gz",
|
||||
"size": 15728640,
|
||||
"created": "2025-10-03T02:00:00.000Z"
|
||||
}
|
||||
],
|
||||
"count": 1
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Restore from Backup
|
||||
|
||||
**Endpoint**: `POST /api/v1/backups/restore?filename=backup.sql.gz`
|
||||
|
||||
**⚠️ WARNING**: This will overwrite the current database!
|
||||
|
||||
```bash
|
||||
curl -X POST "https://api.maternal-app.com/api/v1/backups/restore?filename=postgresql_maternal_app_2025-10-03T02-00-00.sql.gz" \
|
||||
-H "Authorization: Bearer YOUR_ADMIN_TOKEN"
|
||||
```
|
||||
|
||||
## Backup File Formats
|
||||
|
||||
### PostgreSQL Backup
|
||||
- **Format**: Plain SQL with gzip compression
|
||||
- **Extension**: `.sql.gz`
|
||||
- **Command**: `pg_dump | gzip`
|
||||
- **Size**: ~10-50MB (varies by data volume)
|
||||
|
||||
### MongoDB Backup

|
||||
|
||||
## Disaster Recovery
|
||||
|
||||
### Recovery Time Objective (RTO)

||||
- **Process**: Restore from most recent backup + replay WAL logs
|
||||
|
||||
### Recovery Point Objective (RPO)
|
||||
- **Target**: 24 hours (daily backups)
|
||||
- **Improvement**: Enable PostgreSQL WAL archiving for point-in-time recovery
|
||||
|
||||
### Recovery Steps
|
||||
|
||||
1. **Stop the application**:
|
||||
```bash
|
||||
systemctl stop maternal-app
|
||||
```
|
||||
|
||||
2. **Restore PostgreSQL database**:
|
||||
```bash
|
||||
gunzip -c /var/backups/maternal-app/postgresql_*.sql.gz | \
|
||||
psql -h localhost -U maternal_user -d maternal_app
|
||||
```
|
||||
|
||||
3. **Restore MongoDB** (if needed):
|
||||
```bash
|
||||
tar -xzf /var/backups/maternal-app/mongodb_*.tar.gz
|
||||
mongorestore --uri="mongodb://localhost:27017/maternal_ai_chat" ./mongodb_*
|
||||
```
|
||||
|
||||
4. **Restart the application**:
|
||||
```bash
|
||||
systemctl start maternal-app
|
||||
```
|
||||
|
||||
5. **Verify data integrity**:

## Best Practices
|
||||
|
||||
### Production Deployment
|
||||
|
||||
1. **Enable S3 uploads** for off-site storage
|
||||
2. **Set up monitoring** for backup failures
|
||||
3. **Test restoration** quarterly
|
||||
4. **Document procedures** for on-call engineers
|
||||
5. **Encrypt backups** at rest and in transit
|
||||
|
||||
### Monitoring
|
||||
|
||||
Monitor backup health with:
|
||||
- **Success/failure notifications** (email/Slack)
|
||||
- **Backup file size tracking** (detect corruption)
|
||||
- **S3 upload verification**
|
||||
- **Age of last successful backup**
|
||||
|
||||
Example monitoring query:
|
||||
```bash
|
||||
# Check age of last backup
|
||||
find /var/backups/maternal-app -name "postgresql_*.sql.gz" -mtime -1
|
||||
```
|
||||
|
||||
### Security
|
||||
|
||||
1. **Restrict access** to backup files (chmod 600)
|
||||
2. **Encrypt sensitive backups** before S3 upload
|
||||
3. **Rotate S3 access keys** regularly
|
||||
4. **Audit backup access** logs
|
||||
5. **Require MFA** for restoration operations
|
||||
|
||||
## Backup Verification
|
||||
|
||||
### Automated Verification
|
||||
|
||||
The backup service verifies:
|
||||
- ✅ Backup file exists
|
||||
- ✅ File size > 0
|
||||
- ✅ Gzip integrity (`gunzip -t`)
|
||||
|
||||
### Manual Verification (Quarterly)
|
||||
|
||||
1. Create test environment
|
||||
2. Restore latest backup
|
||||
3. Run application smoke tests
|
||||
4. Compare row counts with production
|
||||
5. Document verification results
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Backup Failed - Disk Space
|
||||
|
||||
**Symptom**: Backup fails with "No space left on device"
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# Check disk usage
|
||||
df -h /var/backups
|
||||
|
||||
# Clean up old backups manually
|
||||
find /var/backups/maternal-app -name "*.gz" -mtime +30 -delete
|
||||
|
||||
# Increase retention period (reduce BACKUP_RETENTION_DAYS)
|
||||
```
|
||||
|
||||
### Backup Failed - Database Connection
|
||||
|
||||
**Symptom**: "could not connect to database"
|
||||
|
||||
**Solution**:
|
||||
- Verify `DATABASE_HOST`, `DATABASE_USER`, `DATABASE_PASSWORD`
|
||||
- Check PostgreSQL is running: `systemctl status postgresql`
|
||||
- Test connection: `psql -h $DB_HOST -U $DB_USER -d $DB_NAME`
|
||||
|
||||
### S3 Upload Failed
|
||||
|
||||
**Symptom**: "Access Denied" or "Invalid credentials"
|
||||
|
||||
**Solution**:
|
||||
- Verify S3 bucket exists and is accessible
|
||||
- Check IAM permissions for `PutObject`
|
||||
- Validate `BACKUP_S3_ACCESS_KEY` and `BACKUP_S3_SECRET_KEY`
|
||||
- Test AWS CLI: `aws s3 ls s3://your-bucket-name/`
|
||||
|
||||
## Cost Optimization
|
||||
|
||||
### Storage Costs
|
||||
|
||||
- **S3 Standard-IA**: ~$0.0125/GB/month
|
||||
- **30-day retention**: ~$0.375 for 30GB of backups
|
||||
- **Lifecycle policy**: Move to Glacier after 90 days for long-term archival
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. Use S3 Intelligent-Tiering
|
||||
2. Enable backup compression
|
||||
3. Adjust retention period based on compliance requirements
|
||||
4. Archive old backups to Glacier
|
||||
|
||||
## Compliance
|
||||
|
||||
### GDPR/COPPA
|
||||
|
||||
- **Right to Deletion**: Automated deletion requests backup user data before purge
|
||||
- **Data Portability**: Backups support full data export
|
||||
- **Audit Trail**: All backup/restore operations logged
|
||||
|
||||
### HIPAA (if applicable)
|
||||
|
||||
- **Encryption**: Enable AES-256 encryption for backups
|
||||
- **Access Control**: Require MFA for backup restoration
|
||||
- **Audit Logging**: Track all backup access
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
1. **Point-in-Time Recovery** (PostgreSQL WAL archiving)
|
||||
2. **Incremental backups** (reduce storage costs)
|
||||
3. **Cross-region replication** (disaster recovery)
|
||||
4. **Automated restore testing** (verify backup integrity)
|
||||
5. **Backup metrics dashboard** (Grafana visualization)
