Ansible Role: restic

Description

Restic is a versatile Go based backup solution which supports multiple backends, deduplication and incremental backups.

This role installs restic on a client, configures the backup repositories and optionally sets up cronjobs to run said backups. Aditionally, it will setup executable scripts to run a Backup manually.

Requirements

• bzip2

Role Variables

Name	Default	Description
restic_version	'0.9.5'	The version of Restic to install
restic_install_dir	'/usr/bin'	Install location for the restic binary
restic_script_dir	'~/restic'	Location of the generated backup scripts

restic_backups	[]	A list of dictionaries specifying the files and directories to be backed up
restic_create_cron	false	Should a cronjob be created for each backup

Repos

Restic stores data in repositories. You have to specify at least one repository to be able to use this role. A repository can be local or remote (see the official documentation).

Using an SFTP repository

For using an SFTP backend, the user needs passwordless access to the host. Please make sure to distribute ssh keys accordingly, as this is outside of the scope of this role.

Available variables:

Name	Required	Description
location	yes	The location of the Backend. Currently, Local and SFTP are supported
password	yes	The password used to secure this repository

Example:

restic_repos:
  local:
    location: /srv/restic-repo
    password: securepassword1
  remote:
    location: sftp:user@host:/srv/restic-repo
    password: securepassword2

Backups

A backup specifies a directory or file to be backuped. A backup is written to a Repository defined in restic_repos.

Available variables:

Name	Required	Description
name	yes	The name of this backup. Used together with pruning and needs to be unique.
src	yes	The source directory or file
stdin	no	Is this backup created from a stdin?
stdin_cmd	no (yes if stdin == true)	The command to produce the stdin.
