What is Attic?
--------------
Attic is a deduplicating backup program. The main goal of Attic is to provide
an efficient and secure way to backup data. The data deduplication
technique used makes Attic suitable for daily backups since only changes
are stored.
Easy to use
~~~~~~~~~~~
Initialize backup repository and create a backup archive::
$ attic init /usbdrive/my-backup.attic
$ attic create -v /usbdrive/my-backup.attic::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 a MAC (message authentication code).
Off-site backups
Attic can store data on any remote host accessible over SSH. This is
most efficient if Attic is also installed on the remote host.
Backups mountable as filesystems
Backup archives are mountable as userspace filesystems for easy backup
verification and restores.
What do I need?
---------------
Attic requires Python 3.2 or above to work.
Attic also requires a sufficiently recent OpenSSL (>= 1.0.0).
In order to mount archives as filesystems, llfuse is required.
For other python requirements, please see setup.py install_requires.
How do I install it?
--------------------
::
$ pip install Attic
Where are the docs?
-------------------
Go to https://attic-backup.org/ for a prebuilt version of the documentation.
You can also build it yourself from the docs folder.
Where are the tests?
--------------------
The tests are in the attic/testsuite package. To run the test suite use the
following command::
$ fakeroot -u tox # you need to have tox installed
.. |build| image:: https://travis-ci.org/attic/merge.svg
