Description: 
        What is BorgBackup?
        -------------------
        
        BorgBackup (short: Borg) is a deduplicating backup program.
        Optionally, it supports compression and authenticated encryption.
        
        The main goal of Borg is to provide an efficient and secure way to backup data.
        The data deduplication technique used makes Borg suitable for daily backups
        since only changes are stored.
        The authenticated encryption technique makes it suitable for backups to not
        fully trusted targets.
        
        See the `installation manual`_ or, if you have already
        downloaded Borg, ``docs/installation.rst`` to get started with Borg.
        There is also an `offline documentation`_ available, in mutiple formats.

        Main features
        ~~~~~~~~~~~~~
        
        **Space efficient storage**
          Deduplication based on content-defined chunking is used to reduce the number
          of bytes stored: each file is split into a number of variable length chunks
          and only chunks that have never been seen before are added to the repository.
        
          A chunk is considered duplicate if its id_hash value is identical.
          A cryptographically strong hash or MAC function is used as id_hash, e.g.
          (hmac-)sha256.
        
          To deduplicate, all the chunks in the same repository are considered, no
          matter whether they come from different machines, from previous backups,
          from the same backup or even from the same single file.
        
          Compared to other deduplication approaches, this method does NOT depend on:
        
          * file/directory names staying the same: So you can move your stuff around
            without killing the deduplication, even between machines sharing a repo.
        
          * complete files or time stamps staying the same: If a big file changes a
            little, only a few new chunks need to be stored - this is great for VMs or
            raw disks.
        
          * The absolute position of a data chunk inside a file: Stuff may get shifted
            and will still be found by the deduplication algorithm.
        
        **Speed**
          * performance critical code (chunking, compression, encryption) is
            implemented in C/Cython
          * local caching of files/chunks index data
          * quick detection of unmodified files
        
        **Data encryption**
            All data can be protected using 256-bit AES encryption, data integrity and
            authenticity is verified using HMAC-SHA256. Data is encrypted clientside.
        
        **Compression**
            All data can be optionally compressed:
        
            * lz4 (super fast, low compression)
            * zstd (wide range from high speed and low compression to high compression
              and lower speed)
            * zlib (medium speed and compression)
            * lzma (low speed, high compression)
        
        **Off-site backups**
            Borg can store data on any remote host accessible over SSH.  If Borg is
            installed on the remote host, big performance gains can be achieved
            compared to using a network filesystem (sshfs, nfs, ...).
        
        **Backups mountable as filesystems**
            Backup archives are mountable as userspace filesystems for easy interactive
            backup examination and restores (e.g. by using a regular file manager).
        
        **Easy installation on multiple platforms**
            We offer single-file binaries that do not require installing anything -
            you can just run them on these platforms:
        
            * Linux
            * Mac OS X
            * FreeBSD
            * OpenBSD and NetBSD (no xattrs/ACLs support or binaries yet)
            * Cygwin (experimental, no binaries yet)
            * Linux Subsystem of Windows 10 (experimental)
        
        **Free and Open Source Software**
          * security and functionality can be audited independently
          * licensed under the BSD (3-clause) license, see `License`_ for the
            complete license
        
        Easy to use
        ~~~~~~~~~~~
        
        Initialize a new backup repository (see ``borg init --help`` for encryption options)::
        
            $ borg init -e repokey /path/to/repo
        
        Create a backup archive::
        
            $ borg create /path/to/repo::Saturday1 ~/Documents
        
        Now doing another backup, just to show off the great deduplication::
        
            $ borg create -v --stats /path/to/repo::Saturday2 ~/Documents

        NOT RELEASED DEVELOPMENT VERSIONS HAVE UNKNOWN COMPATIBILITY PROPERTIES.
        
        THIS IS SOFTWARE IN DEVELOPMENT, DECIDE YOURSELF WHETHER IT FITS YOUR NEEDS.
        
        Security issues should be reported to the `Security contact`_ (or
        see ``docs/suppport.rst`` in the source distribution).
