 376      "Rdiff-backup backs up one directory to another, possibly over a network.
 377 The target directory ends up a copy of the source directory, but extra reverse
 378 diffs are stored in a special subdirectory of that target directory, so you
 379 can still recover files lost some time ago.  The idea is to combine the best
 380 features of a mirror and an incremental backup.  Rdiff-backup also preserves
 381 subdirectories, hard links, dev files, permissions, uid/gid ownership,
 382 modification times, extended attributes, acls, and resource forks.  Also,
 383 rdiff-backup can operate in a bandwidth efficient manner over a pipe, like
 384 rsync.  Thus you can use rdiff-backup and ssh to securely back a hard drive up
 385 to a remote location, and only the differences will be transmitted.  Finally,
 386 rdiff-backup is easy to use and settings have sensible defaults.")
