  1. What is Attic?
  2. --------------
  3. Attic is a deduplicating backup program. The main goal of attic is to provide
  4. an efficient and secure way to backup data. The data deduplication
  5. technique used makes Attic suitable for daily backups since only actual changes
  6. are stored.
  7. Easy to use
  8. ~~~~~~~~~~~
  9. Initialze backup repository and create a backup archive::
  10. $ attic init /usbdrive/my-backup.attic
  11. $ attic create -v /usbdrive/my-backup.attic::documents ~/Documents
  12. Main features
  13. ~~~~~~~~~~~~~
  14. Space efficient storage
  15. Variable block size deduplication is used to reduce the number of bytes
  16. stored by detecting redundant data. Each file is split into a number of
  17. variable length chunks and only chunks that have never been seen before are
  18. compressed and added to the repository.
  19. Optional data encryption
  20. All data can be protected using 256-bit AES encryption and data integrity
  21. and authenticity is verified using HMAC-SHA256.
  22. Off-site backups
  23. attic can store data on any remote host accessible over SSH as long as
  24. attic is installed.
  25. Backups mountable as filesystems
  26. Backup archives are mountable as userspace filesystems for easy backup
  27. verification and restores.
  28. What do I need?
  29. ---------------
  30. Attic requires Python 3.2 or above to work. Besides Python attic also requires
  31. msgpack-python and sufficiently recent OpenSSL (>= 1.0.0).
  32. How do I install it?
  33. --------------------
  34. ::
  35. $ pip install Attic
  36. Where are the docs?
  37. -------------------
  38. Go to https://pythonhosted.org/Attic/ for a prebuilt version of the docs. You
  39. can also build them yourself form the docs folder.
  40. Where are the tests?
  41. --------------------
  42. The tests are in the attic/testsuite package. To run the test suite use the
  43. following command::
  44. $ python -m attic.testsuite.run
