Configure duply on top of duplicity to provide a profile-based, easy to use backup and restore system.


Install duplicity and duply with all default values.

class { 'duplicity':
  ensure => present,

Install a more recent version of duply from the sourceforge project page

class { 'duplicity':
  duply_package_provider      => 'archive',
  duply_archive_version       => '2.1',
  duply_archive_checksum      => 'a8d2bfa907aacbef1c66bf1079fa24e541ad63f5d0694029e4596b030f3cb244',
  duply_archive_checksum_type => 'sha256',

Specify the backup server to be used; see the duplicity documentation for more information about the available protocols.

class { 'duplicity':
  backup_target_url      => 'ftps://',
  backup_target_username => 'username',
  backup_target_password => 'password',

In case you're using duply 1.10+ and a storage backend that requires additional environment variables to be set, use the following pattern

class { 'duplicity':
  duply_environment => [
    "export AWS_ACCESS_KEY_ID='${my_access_key}'",
    "export AWS_SECRET_ACCESS_KEY='${my_secret_key}'",

This works on a profile-level as well.

Configure a simple backup profile that stops an application before the backup starts and starts it when complete. It will run once a day, do incremental backups by default and create a full backup if the previous full backup is older than 7 days. Duplicity will keep at most two full backups and purge older ones.

duplicity::profile { 'system':
  full_if_older_than  => '7D',
  max_full_backups    => 2,
  cron_hour           => '4',
  cron_minute         => '0',
  exec_before_content => '/bin/systemctl stop myapp',
  exec_after_content  => '/bin/systemctl start myapp',

Backup a file and restore it from a previous backup if it is not existing. Setting ensure to backup will only backup the file but not restore it.

Note: a directory will only be restored if the directory is not existing - an empty directory is not replaced.

duplicity::file { '/path/to/file':
  ensure => present,

Backup a directory by using a specific backup profile and exclude a bunch of files.

$data_dir = '/var/lib/jira'

duplicity::file { $data_dir:
  profile => 'jira',
  exclude => [

Define a GnuPG key pair BEEF1234 to be used to de/encrypt the backup on the node itself and configure the backup profile to use it. The encrytion key ALICE00001 is used to decrypt the backup on another node (e.g. the admin's workstation).

duplicity::private_key { 'BEEF1234':
  content => hiera('duplicity::private_key::BEEF1234'),

duplicity::public_key { 'BEEF1234':
  content => template('path/to/'),

class { 'duplicity':
  gpg_encryption_keys => ['ALICE00001', 'BEEF1234'],
  gpg_signing_key     => 'BEEF1234',

Or turn off the encryption of backups for a particular profile altogether:

duplicity::profile { 'system':
  gpg_encryption => false,


The module has been tested on the following operating systems. Testing and patches for other platforms are welcome.

  • Debian 9.0 (Stretch)
  • Debian 10.0 (Buster)
  • Ubuntu 16.04 (Xenial Xerus)
  • Ubuntu 18.04 (Bionic Beaver)


  1. Fork it
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create new Pull Request


This project uses rspec-puppet and beaker to ensure the module works as expected and to prevent regressions.

gem install bundler
bundle install --path vendor

bundle exec rake spec
bundle exec rake beaker

(note: see Beaker - Supported ENV variables for a list of environment variables to control the default behaviour of Beaker)


Puppet module to manage backups based on duplicity.
