- ====
- |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
