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 ``puppet master`` 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.
