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

.. code-block:: yaml

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

.. code-block:: yaml

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

Backup client with defined number of backups to keep

..code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: rsync
          host: 10.10.10.208
          user: backupninja
          keep: 4

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


Client scheduling in rsync engine
=================================

Client run backup at 5am every day.

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: rsync
        scheduling:
          when:
            - everyday at 05


Client run backup in mupltiple times.

.. code-block:: yaml

    backupninja:
      client:
        enabled: true
        target:
          engine: rsync
        scheduling:
          when:
            - everyday at 5
            - Tuesday at 05:30
            - 25 at 23:45
            - hourly

If multiple "when" options are present, then they all apply. If two configurations files are scheduled to run in the same hour, then we fall back on the alphabetical ordering specified above.
