Attic seems good. Its encryption makes me uneasy (https://github.com/jborg/attic/blob/master/attic/key.py), and I don't feel qualified to review it:

  * use of pkbdf2(passphrase)[0:32] as encryption key?
  * is AES correctly used? there are many pitfalls

I would be much more comfortable with it using gpg for encryption.
