- What is darc?
- -------------
- Darc is a Deduplicating ARChiver written in Python. The main goal of darc is
- to provide an efficient and secure way to backup data. The data deduplication
- technique used makes darc suitable for daily backups since only actual changes
- are stored.
- Easy to use
- ~~~~~~~~~~~
- Initialze backup repository and create a backup archive::
- $ darc init /usbdrive/my-backup.darc
- $ darc create -v /usbdrive/my-backup.darc::documents ~/Documents
- 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
- darc can store data on any remote host accessible over SSH as long as
- darc is installed.
- What do I need?
- ---------------
- Darc requires Python 3.2 or above to work. Besides Python darc also requires
- msgpack-python and sufficiently recent OpenSSL (>= 1.0.0).
- How do I install it?
- --------------------
- ::
- $ python setup.py install
- Where are the docs?
- -------------------
- Go to https://pythonhosted.org/darc/ for a prebuilt version of the docs. You
- can also build them yourself form the docs folder.
- Where are the tests?
- --------------------
- The tests are in the darc/testsuite package. To run the test suite use the
- following command::
- $ python -m darc.testsuite.run
- Where can I get help?
- ---------------------
- Send questions, comments, patches, etc. to jonas@borgstrom.se. Issues and
- pull requests can also be created on https://github.com/jborg/darc
