Restic
Homepage: https://restic.net/
Restic is a modern backup program that can back up your files.
Usage
Basic
Set restic_enabled: true in your inventories/<your_inventory>/group_vars/nas.yml file.
Set all the restic variables that you need (see defaults/main.yml for reference), especially the restic_repos and restic_backups variable to have your remotes added to restic config.
Consult arillso.restic role and Restic documentation for details.
Other info
This role is mostly relying on existing arillso.restic role, but actually creates the backup scripts by itself, in order to add support for restic extended options (options under restic_backups) to play nicely with Rclone remotes.
