and uploading them to a remote or local file server.  Because duplicity uses
librsync, the incremental archives are space efficient and only record the
parts of files that have changed since the last backup.  Because duplicity
uses GnuPG to encrypt and/or sign these archives, they will be safe from
spying and/or modification by the server.")
