Database Backups and Recovery Strategy

Backups are part of professional engineering. The goal is simple: recover data quickly after mistakes or failures.

    A practical strategy includes:
    - automated daily backups
    - encrypted storage
    - periodic restore tests
    
    ## Backup workflow (high-level)
    
    ```mermaid

      A[(Database)] --> B[Backup Job]
      B --> C[Encrypted File]
      C --> D[Offsite Storage]
      D --> E[Restore Testing]
    ```
    
    A backup is only valuable if restoring works, so scheduled restore testing matters.
