NAME

6       amcryptsimple - reference simple crypt program for Amanda symmetric
7       data encryption
8

SYNOPSIS

10       amcryptsimple  to be called by Amanda only
11

DESCRIPTION

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

HOW TO CREATE PASSPHRASE

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

NOTES

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.
