rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago.The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. Finally, rdiff-backup is easy to use and settings have sensical defaults. Here are some key features of "rdiff-backup": · Easy to use · Creates mirror · Keeps increments · Preserves all information · Space efficient · Bandwidth efficient · Transparent data format · Filesystem feature autodetection · Mac OS X resource fork support · ACL and EA support · Keeps statistics Requirements: · Python · librsync · pylibacl · pyxattr What's New in This Release: · The --min-file-size and --max-file-size options were changed to agree with the man page. These options no longer include files, and will only apply to regular files. · Python 2.2 compatibility was fixed. · The program no longer crashes when the file system can't set the requested ACL. · The error message that is shown if a regress fails due to a security violation was improved. · The --override-chars-to-quote option was fixed.
