 405 The target directory ends up a copy of the source directory, but extra reverse
 406 diffs are stored in a special subdirectory of that target directory, so you
 407 can still recover files lost some time ago.  The idea is to combine the best
 408 features of a mirror and an incremental backup.  Rdiff-backup also preserves
 409 subdirectories, hard links, dev files, permissions, uid/gid ownership,
 410 modification times, extended attributes, acls, and resource forks.  Also,
 411 rdiff-backup can operate in a bandwidth efficient manner over a pipe, like
 412 rsync.  Thus you can use rdiff-backup and ssh to securely back a hard drive up
 413 to a remote location, and only the differences will be transmitted.  Finally,
 414 rdiff-backup is easy to use and settings have sensible defaults.")

 972     (description "Restic is a program that does backups right and was designed
 973 with the following principles in mind:
 974
 975 @itemize
 976 @item Easy: Doing backups should be a frictionless process, otherwise you
 977 might be tempted to skip it.  Restic should be easy to configure and use, so
 978 that, in the event of a data loss, you can just restore it.  Likewise,
 979 restoring data should not be complicated.
 980
 981 @item Fast: Backing up your data with restic should only be limited by your
 982 network or hard disk bandwidth so that you can backup your files every day.
 983 Nobody does backups if it takes too much time.  Restoring backups should only
 984 transfer data that is needed for the files that are to be restored, so that
 985 this process is also fast.
 986
 987 @item Verifiable: Much more important than backup is restore, so restic
 988 enables you to easily verify that all data can be restored.  @item Secure:
 989 Restic uses cryptography to guarantee confidentiality and integrity of your
 990 data.  The location the backup data is stored is assumed not to be a trusted
 991 environment (e.g.  a shared space where others like system administrators are
 992 able to access your backups).  Restic is built to secure your data against
 993 such attackers.
 994
 995 @item Efficient: With the growth of data, additional snapshots should only
 996 take the storage of the actual increment.  Even more, duplicate data should be
 997 de-duplicated before it is actually written to the storage back end to save
 998 precious backup space.
