Duplicity is a software suite that provides encrypted, digitally signed, versioned, remote backup of files requiring little of the remote server.〔(Linux Journal: An Automated Reliable Backup Solution )〕 Released under the terms of the GNU General Public License (GPL), Duplicity is free software. Duplicity devises a scheme where the first archive is a complete (full) backup, and subsequent (incremental) backups only add differences from the latest full or incremental backup.〔(Duplicity Website: Features )〕 Chains consisting of a full backup and a series of incremental backups can be recovered to the point in time that any of the incremental steps were taken. If any of the incremental backups are missing then the incremental backups following it cannot be reconstructed. It does this using GnuPG, librsync, tar, and rdiff.〔 To transmit data to the backup repository it can use SSH/SCP/SFTP, local file access, rsync, FTP, Amazon S3,〔(Bash Script: Incremental Encrypted Backups with Duplicity (Amazon S3) )〕 Google Cloud Storage,〔(Change log of version 0.6.22 )〕 Rackspace Cloud Files,〔(A fork of dt-s3-backup to use with Rackspace Cloud Files )〕 and others. Refer to its (man page ) for the constantly growing list of back-ends. Duplicity works best under Unix-like operating systems (such as Linux, BSD, and Mac OS X),〔(Installing Duplicity on OS/X 10.5 (Leopard) )〕 though it can be used with Windows under Cygwin. Currently duplicity supports deleted files, full Unix permissions, directories, and symbolic links, fifos, and device files, but not hard links. ==See also== *List of backup software *Duplicati is a C# re-implementation of Duplicity 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Duplicity (software)」の詳細全文を読む スポンサード リンク
