cwDup is tested successfully with local file, rsync, ftp and sftp as backend transfer methods. There are many ways to use Duplicity. Please consult Duplicity documentation and man page for details.

The recipe below is just for a kickstart:


  • Client installation includes the shell script bin\ starting cwDup in a right environment:
source /bin/

# Customize contents with your duplicity command
# See Duplicity examples on Internet

# Don't forget the encryption key below, otherwise your backups are useless.
export PASSPHRASE=your-encryption-key

# Some examples

# Local
#duplicity /home/user/src file:///home/user/dest

# Rsync
#duplicity /home/user/src rsync://user@localhost::dest

# Ftp, ncftp is used as backend
#export FTP_PASSWORD=password-for-ftp-connection-below
#duplicity /home/user/src ncftp+ftp://user@host

# SFTP, pexpect is used as backend
#export FTP_PASSWORD=password-for-sftp-connection-below
#duplicity /home/user/src pexpect+sftp://user@host/temp


  • The script above is called from the Windows batch file cwdup.cmd available at the root of the installation directory. You can schedule it according to your needs.
