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

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

1029 re-use any data found in any previous backups.  This way only new
1030 changes are stored, and as long as the files are not very different,
1031 the amount of storage required is very low.  Any of the backup files
1032 stored previously can be read back in full at any time.  The program
1033 is format-agnostic, so you can feed virtually any files to it.")
