Setting up postgres backup (optional)

The playbook can install and configure docker-postgres-backup-local for you via the 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 instead.

Adjusting the playbook configuration

Minimal working configuration (inventory/host_vars/matrix.DOMAIN/vars.yml) to enable Postgres backup:

postgres_backup_enabled: true

Refer to the table below for additional configuration variables and their default values.

Name	Default value	Description
postgres_backup_enabled	false	Set to true to use docker-postgres-backup-local to create automatic database backups
postgres_backup_schedule	'@daily'	Cron-schedule specifying the interval between postgres backups.
postgres_backup_keep_days	7	Number of daily backups to keep
postgres_backup_keep_weeks	4	Number of weekly backups to keep
postgres_backup_keep_months	12	Number of monthly backups to keep
postgres_backup_base_path	"{{ matrix_base_data_path }}/postgres-backup"	Base path for postgres-backup. Also see postgres_backup_data_path
postgres_backup_data_path	"{{ postgres_backup_base_path }}/data"	Storage path for postgres-backup database backups

Installing

After configuring the playbook, run the installation command again:

ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
