# Postgres Backup

This playbook can configure [docker-postgres-backup-local](https://github.com/prodrigestivill/docker-postgres-backup-local) for you via the [com.devture.ansible.role.postgres_backup](https://github.com/devture/com.devture.ansible.role.postgres_backup) Ansible role.

For a more complete backup solution (one that includes not only Postgres, but also other configuration/data files), you may wish to look into [borg backup](backup-borg.md).


## Configuration

To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
