Backupninja formula
===================

Backupninja allows you to coordinate system backup by dropping a few simple
configuration files into /etc/backup.d/. Most programs you might use for
making backups don't have their own configuration file format.

Backupninja provides a centralized way to configure and schedule many
different backup utilities. It allows for secure, remote, incremental
filesytem backup (via rdiff-backup), compressed incremental data, backup
system and hardware info, encrypted remote backups (via duplicity), safe
backup of MySQL/PostgreSQL databases, subversion or trac repositories, burn
CD/DVDs or create ISOs, incremental rsync with hardlinking.


Sample pillars
==============

Backup client with ssh/rsync remote target

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: rsync
          host: 10.10.10.208
          user: backupninja

Backup client with ssh/rsync remote target with specific rsync options

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: rsync
          engine_opts: "-av --delete --recursive --safe-links"
          home_dir: /srv/volumes/backup/backupninja
          host: 10.10.10.208
          user: backupninja

Backup client with s3 remote target

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: dup
          url: s3+http://bucket-name/folder-name
          auth:
            awsaccesskeyid: awsaccesskeyid
            awssecretaccesskey: awssecretaccesskey

Backup client with webdav target

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: dup
          url: webdavs://backup.cloud.example.com/box.example.com/
          auth:
            gss:
              principal: host/${linux:network:fqdn}
              keytab: /etc/krb5.keytab

Backup client with exact backup times


.. note:: This settings will configure global backupninja backup to be
   triggered at exactly set times.

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        auto_backup_disabled: false
        backup_times:
          day_of_week: 1
          hour: 2
          minute: 32

.. note:: This will trigger backup every monday at 2:32 AM.

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        auto_backup_disabled: false
        backup_times:
          day_of_month: 24
          hour: 14
          minute: 12

.. note:: This will trigger backup every 24th day of every month at 14:12 (2:12 PM).

.. note:: Available parameters:
   ``day_of_week`` (0, 3, 6 ...). If not set, defaults to '*'.
   ``day_of_month`` (20, 25, 12, ...). If not set, defaults to '*'.
     Only ``day_of_week`` or ``day_of_month`` can be defined at the same time.
   ``hour`` (1, 10, 15, ...). If not defined, defaults to `1`. Uses 24 hour format.
   ``minute`` (5, 10, 59, ...). If not defined, defaults to `00`.

..note:: Parameter ``auto_backup_disabled`` is optional. It disables automatic
  backup when set to true. It's set to ``false``by default when not defined.

Backup server rsync/rdiff

.. code-block:: yaml

    backupninja:
      server:
        enabled: true
        rdiff: true
        key:
          client1.domain.com:
            enabled: true
            key: ssh-key

Backup server without strict client policy restriction

.. code-block:: yaml

    backupninja:
      server:
        restrict_clients: false

Backup client with local storage

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: local
