Database Backups

It is strongly recommended to implement automated daily backups of your PostgreSQL database with a minimum retention period of 30 days for optimal data protection. Always perform a full database backup or server snapshot before upgrading between releases, as each release includes automatic database migrations that may introduce breaking changes.

​
Backup Strategies

  • Automated daily backups with point-in-time recovery capabilities
  • Pre-upgrade snapshots before any version migration
  • Cross-region replication for disaster recovery scenarios
  • Encrypted backup storage to ensure data security
The specific implementation details for PostgreSQL backups depend on your hosting infrastructure and deployment architecture. Refer to the official PostgreSQL backup documentation for comprehensive backup strategies.

​
Basic Backup and Restore Commands

Create a database backup: 
pg_dump -h <host> -p <port> -U <username> -W <database_name> > backup.sql
Restore from backup: 
psql -h <host> -p <port> -U <username> -W <database_name> < backup.sql
Replace <host>, <port>, <username>, and <database_name> with your actual database connection details.

​
Environment Configuration

If your deployment environment lacks secure secret management capabilities and relies on .env files for configuration, ensure these files are backed up after every modification. Store backups in encrypted repositories or password managers with proper access controls.

​
Critical Environment Variables

Backup the following configuration files:
  • Database connection strings
  • API keys and authentication tokens
  • SMTP configuration for email notifications
  • Redis connection parameters (if applicable)
