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
|
