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

 948     (description "Restic is a program that does backups right and was designed
 949 with the following principles in mind:
 950
 951 @itemize
 952 @item Easy: Doing backups should be a frictionless process, otherwise you
 953 might be tempted to skip it.  Restic should be easy to configure and use, so
 954 that, in the event of a data loss, you can just restore it.  Likewise,
 955 restoring data should not be complicated.
 956
 957 @item Fast: Backing up your data with restic should only be limited by your
 958 network or hard disk bandwidth so that you can backup your files every day.
 959 Nobody does backups if it takes too much time.  Restoring backups should only
 960 transfer data that is needed for the files that are to be restored, so that
 961 this process is also fast.
 962
 963 @item Verifiable: Much more important than backup is restore, so restic
 964 enables you to easily verify that all data can be restored.  @item Secure:
 965 Restic uses cryptography to guarantee confidentiality and integrity of your
 966 data.  The location the backup data is stored is assumed not to be a trusted
 967 environment (e.g.  a shared space where others like system administrators are
 968 able to access your backups).  Restic is built to secure your data against
 969 such attackers.
 970
 971 @item Efficient: With the growth of data, additional snapshots should only
 972 take the storage of the actual increment.  Even more, duplicate data should be
 973 de-duplicated before it is actually written to the storage back end to save
 974 precious backup space.

1007 re-use any data found in any previous backups.  This way only new
1008 changes are stored, and as long as the files are not very different,
1009 the amount of storage required is very low.  Any of the backup files
1010 stored previously can be read back in full at any time.  The program
1011 is format-agnostic, so you can feed virtually any files to it.")
