7 data encryption

10 amcryptsimple to be called by Amanda only
11
13 amcryptsimple calls gpg to perform symmetric data encryption on Amanda
14 backup. amcryptsimple will search for the gpg program in the following
15 directories: /usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin
16
17 amcryptsimple uses one passphrase to encrypt the Amanda data and uses
18 the same passphrase to decrypt the Amanda backup data. amcryptsimple
19 uses AES256 as the symmetric cipher.
20
22 Store the passphrase inside the home-directory of the Amanda user
23 ($amanda_user) and protect it with proper permissions:
24
25 echo my_secret_passphrase > ~$amanda_user/.am_passphrase
26 chown $amanda_user:disk ~$amanda_user/.am_passphrase
27 chmod 700 ~$amanda_user/.am_passphrase
28
30 Choose a good passphrase and protect it properly. Backup data can only
31 be restored with the passphrase. There is no backdoor.
32
33 If storing and securing passphrase in your environment presents
34 challenges, Amanda provide public-key data encryption through
35 amgpgcrypt. Public-key encryption uses the public key to encrypt and
36 uses the private key to decrypt.
