@doc = "A repository for backing up files. If no filebucket is
defined, then files will be backed up in their current directory,
but the filebucket can be either a host- or site-global repository
for backing up. It stores files and returns the MD5 sum, which
can later be used to retrieve the file if restoration becomes
necessary. A filebucket does not do any work itself; instead,
it can be specified as the value of *backup* in a **file** object.
Currently, filebuckets are only useful for manual retrieval of
accidentally removed files (e.g., you look in the log for the md5 sum and retrieve the file with that sum from the filebucket), but
when transactions are fully supported filebuckets will be used to
undo transactions.
You will normally want to define a single filebucket for your
whole network and then use that as the default backup location:
# Define the bucket
filebucket { main: server => puppet }
# Specify it as the default target
File { backup => main }
Puppetmaster servers create a filebucket by default, so this will
work in a default configuration."

in the config or at the commandline is used."
