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.

**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.
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 will 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.
**Compression**
All data can be compressed by zlib, level 0-9.
**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 to use
~~~~~~~~~~~
Initialize a new backup repository and create a backup archive::
$ borg init /mnt/backup
$ borg create /mnt/backup::Monday ~/Documents
Now doing another backup, just to show off the great deduplication::
$ borg create --stats /mnt/backup::Tuesday ~/Documents
Archive name: Tuesday

BORG IS NOT COMPATIBLE WITH ORIGINAL ATTIC.
EXPECT THAT WE WILL BREAK COMPATIBILITY REPEATEDLY WHEN MAJOR RELEASE NUMBER
CHANGES (like when going from 0.x.y to 1.0.0). Please read CHANGES document.
NOT RELEASED DEVELOPMENT VERSIONS HAVE UNKNOWN COMPATIBILITY PROPERTIES.
THIS IS SOFTWARE IN DEVELOPMENT, DECIDE YOURSELF WHETHER IT FITS YOUR NEEDS.

fork: s/attic/borg/g, fix URLs, add new section to AUTHORS use borg instead attic except at the places where it was used: - as toplevel package name, directory name, file name - to refer to original attic remove sphinx upload make command, will be replaced by github.io site later remove references to binary downloads and linux packages for now remove some software name references, fix grammar use borgbackup rather than borg-backup (or borg) in URLs, less name collision issues, better search results, no validity issues with "-"
