retrieving entire files from remote servers. As Puppet matures, it
expected that the ``file`` resource will be used less and less to
manage content, and instead native resources will be used to do so.
If you find that you are often copying files in from a central
location, rather than using native resources, please contact
Reductive Labs and we can hopefully work with you to develop a
native resource to support what you are doing."

newparam(:backup) do
desc "Whether files should be backed up before
being replaced. The preferred method of backing files up is via
a ``filebucket``, which stores files by their MD5 sums and allows
easy retrieval without littering directories with backups. You
can specify a local filebucket or a network-accessible
server-based filebucket by setting ``backup => bucket-name``.
Alternatively, if you specify any value that begins with a ``.``
(e.g., ``.puppet-bak``), then Puppet will use copy the file in
the same directory with that value as the extension of the
backup. Setting ``backup => false`` disables all backups of the
file in question.
Puppet automatically creates a local filebucket named ``puppet`` and
defaults to backing up there. To use a server-based filebucket,
you must specify one in your configuration::
filebucket { main:
server => puppet
}
The ``puppetmasterd`` daemon creates a filebucket by default,
so you can usually back up to your main server with this
configuration. Once you've described the bucket in your
configuration, you can use it in any file::
file { \"/my/file\":
source => \"/path/in/nfs/or/something\",
backup => main
}
This will back the file up to the central server.
At this point, the benefits of using a filebucket are that you do not
have backup files lying around on each of your machines, a given
version of a file is only backed up once, and you can restore
any given file manually, no matter how old. Eventually,
transactional support will be able to automatically restore
filebucketed files.
