 These variables apply to both directory and PostgreSQL backups.
 
-- **`BACKUP_MODE`** _(optional)_ - Defines the backup type (`directory` or `postgres`). Defaults to `directory`.
-- **`RESTIC_PASSWORD`** _(required)_ - The encryption password for Restic.
-- **`RESTIC_REPOSITORY`** _(required)_ - The URI of the Restic repository (e.g., `rest:http://your-rest-server:8000/backup`).
