duplicity: duplicity (Encrypted bandwidth-efficient backup using rsync algorithm) duplicity: duplicity: Duplicity backs directories by producing encrypted tar-format volumes duplicity: and uploading them to a remote or local file server. Because duplicity duplicity: uses librsync, the incremental archives are space efficient and only duplicity: record the parts of files that have changed since the last backup. duplicity: Because duplicity uses GnuPG to encrypt and/or sign these archives, duplicity: they will be safe from spying and/or modification by the server. duplicity: duplicity: duplicity:
