This role can also set up a new repository on BorgBase, using the arguments below. Thanks to Philipp Rintz for contribution of this feature.

• create_repo: Whether to let the role create the repository for the server. Default: False
• bb_token: Your BorgBase.com API-Token. Should be Create Only for security reasons.
• bb_region: Which region the backups should be saved in. Choice: "eu" or "us".
• bb_new_sshkey: Whether to use the automatically created SSH_key. Default: True
• bb_sshkey: If there is a key already available on BorgBase.com that should be used, it can be set with this variable. The key needs to be exactly the same, including key-comment.
• bb_append: Should the permission of the newly created repository be append only? Default: True
• bb_quota: To use a quota for the Server. Default: False
• bb_quota_size: Will need to be set if bb_quota is set to True. In Gigabyte.
• bb_alertdays: After how many days of no backup activity should alerts be sent out? Defaults to off.

You can also use the BorgBase-Ansible module directly if needed:

  borgbase:
    repository_name: "{{ inventory_hostname }}"
    token: "Your Borgbase API Token"
    new_ssh_key: True
    ssh_key: "{{ some_variable }}"
    append_only: True
    quota_enable: True
    quota: 1000 #in GB
    region: eu
    alertdays: 2
  delegate_to: localhost

• Testing
• Multiple repos in one role-call instead of callng this role multiple times.
• Support more OSs, like Red Hat/Fedora/CentOS, SuSE, Gentoo, Slackware, Arch, BSD
