# == Class: cinder::backup::nfs
#
# Setup Cinder to backup volumes into NFS
#
# === Parameters
#
# [*backup_share*]
# (required) The NFS share to attach to, to be specified in
# fqdn:path, ipv4addr:path, or "[ipv6addr]:path" format.
#
# [*backup_driver*]
# (optional) The backup driver for NFS back-end.
# Defaults to 'cinder.backup.drivers.nfs'.
#
# [*backup_file_size*]
# (optional) The maximum size in bytes of the files used to hold
# backups. If the volume being backed up exceeds this size, then
# it will be backed up into multiple files. This must be a multiple
# of the backup_sha_block_size_bytes parameter.
# Defaults to 1999994880
#
# [*backup_sha_block_size_bytes*]
# (optional) The size in bytes that changes are tracked for
# incremental backups.
# Defaults to 32768
#
# [*backup_enable_progress_timer*]
# (optional) Enable or Disable the timer to send the periodic
# progress notifications to Ceilometer when backing up the volume
# to the backend storage.
# Defaults to true
#
# [*backup_mount_point_base*]
# (optional) The base directory containing the mount point for the
# NFS share.
# Defaults to '$state_path/backup_mount'
#
# [*backup_mount_options*]
# (optional) The mount options that are passed to the NFS client.
# Defaults to undef
#
# [*backup_container*]
# (optional) Custom container to use for backups.
# Defaults to undef
#
# [*backup_compression_algorithm*]
# (optional) Compression algorithm to use when writing backup data.
# Defaults to 'zlib'
