charm-juju-backup-all

Description

Juju Backup All - a charm to perform Juju and database backups

This charm deploys juju-backup-all, along with a script to automate its execution, auto_backup.py. In addition, a crontab is deployed to run auto_backup.py, as well as a Nagios check which alerts on any issues when performing backups.

Usage

Deploy this charm with:

juju deploy juju-backup-all

The following Juju connection config values must be set to allow libjuju to connect controllers and models to perform the backups. It is HIGHLY recommended that a new user be created for backups (will need admin permissions so it can run actions as well as ssh to the units to gather the backup files) on all the model defined:

• controllers - YAML defining the configuration for controllers, same syntax as used by the juju client configuration (usually located at ~/.local/share/juju/controllers.yaml)
• accounts - YAML defining the configuration for juju accounts, same syntax as used by the juju client configuration (usually located at ~/.local/share/juju/accounts.yaml)

The following options are available:

• backup-dir - The directory to be used for the backups. Will be created if it does not exist.
• backup-retention-period - Retention period for backups in days. Backup files older than this will be purged during the next backup run.
• controller-names - A comma delimited list of controller names to be backed up. An empty list means that all configured controllers will backed up.
• crontab - Specifies when to run the backups. Uses standard crontab syntax.
• exclude-charms - A comma delimited list of charms to be excluded. An empty list means that all charms supported by juju-backup-all will be backed up. Note that this setting uses the name of the charm and not the name of the application.
• exclude-controller-backup - Whether to backup the controller as part of the backup operations
• exclude-juju-client-config-backup - Whether to backup the juju client data (accounts, controllers, ssh keys) as part of the backup operations.
• timeout - Timeout in seconds for long running commands. This setting is used for each task and not for the whole backup operation.

Relations

charm-juju-backup-all supports the nagios-external-master relation and provides a NRPE check to ensure that backups are working properly.
