Amanda module for Puppet

Description

Provides Amanda Network Backup server and client configuration through Puppet

Usage

The amanda module allows specifying parameterized classes that will do most of the heavy lifting in a single definition (relying on sane defaults), or for more custom configuration the utility defines can be used directly. What follows is a minimal-effort configuration that trusts the module to figure out the details.

node 'backup.cat.pdx.edu' {
  class { 'amanda::server':
    configs        => [ 'daily', 'archive' ],
    configs_source => 'modules/data/amanda',
  }
}

node 'client.cat.pdx.edu' {
  class { 'amanda::client':
    server => 'backup.cat.pdx.edu',
  }
}

Of note is the configs_source parameter. While the amanda module will install and configure server and client machines, it does not yet attempt to build amanda configs using puppet code. Rather, that legwork is still left up to the administrator, and the module will only ensure that the files which comprise the config are present on the server.

Additional parameters are available for both the amanda::server and amanda::client classes which are not documented here. At present the only way to look up how to use them is to read the source.

How Configs Work

Use the following Puppet DSL code to ensure the "daily" and "archive" configs are created on an amanda backup server.

node 'backup.cat.pdx.edu' {
  file { '/etc/amanda':
    ensure => directory;
  }

  amanda::config { 'daily':
    ensure            => present,
    configs_source    => 'modules/data/amanda',
    configs_directory => '/etc/amanda',
  }
  amanda::config { 'archive':
    ensure            => present,
    configs_source    => 'modules/data/amanda',
    configs_directory => '/etc/amanda',
  }
}

Then place your config files in the "files" directory of the module specified with the configs_source parameter. For the code above, files that make up the "archive" and "daily" amanda configs should be placed in the data module as per this example:

data
|-- files
|   `-- amanda
|       |-- daily
|       |   |-- amanda.conf
|       |   |-- chg-multi.conf
|       |   |-- disklist
|       |   `-- label-templates
|       |       |-- 3hole.ps
|       |       |-- 8.5x11.ps
|       |       |-- DIN-A4.ps
|       |       |-- DLT-A4.ps
|       |       |-- DLT.ps
|       |       |-- EXB-8500.ps
|       |       |-- HP-DAT.ps
|       |       `-- tapetypes.conf
|       `-- archive
|           |-- amanda.conf
|           |-- chg-scsi.conf
|           |-- disklist
|           `-- dumptypes.conf
|-- LICENSE
`-- README

The contents of the config directory ("daily" or "archive") will be synced as file resources to the location specified with the configs_directory specified in the amanda::config resource. For the example above, the files will be synced to the agent system as:

/
|-- etc
|   |-- amanda
|   |   |-- daily
.   |   |   |-- amanda.conf
.   .   |   |-- chg-multi.conf
.   .   |   |-- disklist
    .   |   `-- label-templates
        |       |-- 3hole.ps
        |       |-- 8.5x11.ps
        |       |-- DIN-A4.ps
        |       |-- DLT-A4.ps
        |       |-- DLT.ps
        |       |-- EXB-8500.ps
        |       |-- HP-DAT.ps
        |       `-- tapetypes.conf
        `-- archive
            |-- amanda.conf
            |-- chg-scsi.conf
            |-- disklist
            `-- dumptypes.conf

Additional Types

Besides the primary classes amanda::server and amanda::client, three utility defines are included in the module.

Amanda::Amandahosts

The amanda::amandahosts type manages the .amandahosts file, which controls access to amanda services. The important parameter to this resource is content, and the user must specify the full access line to include. For example,

amanda::amandahosts { 'replicator-amdump':
  content => "replicator.cat.pdx.edu backup amdump",
}

Amanda::Config

The amanda::config type synchronizes a directory of files in a given module to a client. A more detailed example is given in the preceding section.

amanda::config { 'daily':
  ensure            => present,
  configs_source    => 'modules/data/amanda',
  configs_directory => '/etc/amanda',
}

Amanda::Ssh_authorized_key

The amanda::ssh_authorized_key type is a convenience define used to install ssh authentication on an amanda client. The important parameter for this type is key.

amanda::ssh_authorized_key { 'replicator':
  key => hiera('pubkey/backup@replicator'),
}

Known Issues

• It doesn't have any kind of storeconfigs magic that could be used to dynamically generate the disklist file. That would be pretty cool. Totally haven't done it yet.

• The module does not include tests

• The module does not allow overriding of the client/server package name(s)
