Introduction

Juju-backup-all allows operators to perform backups across all juju controllers and models. It provides auto-discovery, backing up all applications of supported charms. The tool also includes options to exclude charms, select which juju controllers to backup, and backup local juju configs.

Supported charms:

• etcd
• postgresql
• mysql-innodb-cluster

Supported juju backups:

• Juju configs
• Juju controllers

Installation

Install juju-backup-all from Snap Store with:

snap install juju-backup-all

Then, make sure the appropriate interfaces are plugged:

snap connect juju-backup-all:juju-client-observe
snap connect juju-backup-all:ssh-keys

Usage

This tool primarily auto-discovers controllers/charms that need backing up. To backup the current controller, simply run:

juju-backup-all

This will backup all apps of all models (in the current controller) of supported charms and output them into juju-backups/ directory. It will also backup the local juju client config.

For a more complex command, here's an example that specifies an output directory, excludes certain charms, excludes the juju client config backup, and runs backups on all controllers.

juju-backup-all -o my/backups/ -e postgresql -e etcd  --all-controllers

The following command will give all the possible arguments that can be passed to the tool:

juju-backup-all -h

Security

The exporter server is an HTTP server built with the prometheus_client library, and designed to work with charm-juju-backup-all. It collects the backup results from the charms and exposes them over the HTTP protocol. The exporter service currently only supports HTTP, so the communication is not encrypted.
