- 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 HMAC-SHA256.
- 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. Besides Python, Attic also requires
- msgpack-python and sufficiently recent OpenSSL (>= 1.0.0).
- In order to mount archives as filesystems, llfuse is required.
- 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 python -m attic.testsuite.run
