|project_name| is a Deduplicating ARChiver written in Python.
The main goal of |project_name| is to provide an efficient and secure way
to backup data. The data deduplication technique used makes |project_name|
suitable for taking daily backups.
Main Features
-------------
Space efficient storage
Variable block size `deduplication`_ is used to reduce the number of bytes
stored by detecting redundant data. Each file is split into a number of
variable length chunks and only chunks that have never been seen before
are compressed and added to the repository.
Optional data encryption
All data can be protected using 256-bit AES_ encryption and data integrity
and authenticity is verified using `HMAC-SHA256`_.
Off-site backups
|project_name| can store data on any remote host accessible over SSH as
long as |project_name| is installed.
Easy to use
-----------
Initialize a new backup :ref:`repository <repository_def>` and create your
first backup :ref:`archive <archive_def>` in two lines::
$ darc init /usbdrive/my-backup.darc
$ darc create -v /usbdrive/my-backup.darc::documents ~/Documents
See the :ref:`generalusage` section for more detailed examples.
Easy installation
-----------------
You can use pip to install |project_name| quickly and easily::
$ pip install darc
