NAME

       amcrypt - reference crypt program for Amanda symmetric data encryption

SYNOPSIS

       amcrypt

DESCRIPTION

       amcrypt requires aespipe, uuencode and gpg to work. Aespipe is available from : http://loop-aes.sourceforge.net

       amcrypt will search for the aespipe program in the following directories: /usr/bin:/usr/local/bin:/sbin:/usr/sbin.

       amcrypt calls amaespipe and pass the passphrase through file descriptor 3. The passphrase should be stored in ~amanda/.am_passphrase.

HOW TO CREATE ENCRYPTION KEYS FOR AMCRYPT

       1. Create 65 random encryption keys and encrypt those keys using gpg. Reading from /dev/random may take indefinitely long if kernel's
       random entropy pool is empty. If that happens, do some other work on some other console (use keyboard, mouse and disks).

       head -c 2925 /dev/random | uuencode -m - | head -n 66 | tail -n 65  | gpg --symmetric -a > ~amanda/.gnupg/am_key.gpg

       This will ask for a passphrase. Remember this passphrase as you will need it in the next step.

       2. Store the passphrase inside the home-directory of the AMANDA-user and protect it with proper permissions:
       echo my_secret_passphrase > ~amanda/.am_passphrase
       chown amanda:disk ~amanda/.am_passphrase
       chmod 700 ~amanda/.am_passphrase

KEY AND PASSPHRASE

       amcrypt uses the same key to encrypt and decrypt data.

       It is very important to store and protect the key and the passphrase properly. Encrypted backup data can only be recovered with the correct
       key and passphrase.

NAME

       amanda-applications - Application-api for amanda

DESCRIPTION

       Describe how to use application with Amanda

APPLICATIONS

       This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To
       information, consult the Amanda wiki at http://wiki.zmanda.com.

       o   amgtar(8), - use GNU Tar to backup and restore data.

       o   ampgsql(8), - use PostgreSQL's continuous WAL archiving.

       o   amraw(8), - use open and read to read the data.

       o   amsamba(8), - use smbclient to backup and restore data.

       o   amstar(8), - use star to backup and restore data.

       o   amsuntar(8), - use native tar on Solaris to backup and restore data.

       o   amzfs-sendrecv(8), - use zfs to create a snapshot and use 'zfs send' to generate the backup.

       o   amzfs-snapshot(8), - use zfs to create a snapshot and for use with other applications (e.g. amgtar)

DEFINING APPLICATIONS

       An application is defined in amanda.conf(5) as follows:

       define application-tool $appconfigname {
	  plugin "$pluginname"
	  property "$PROPERTY_NAME" "$PROPERTY_VALUE"
	  ...
       }
       and then referenced in a dumptype as

       define dumptype $dumptypename {
	  ...
	  program "APPLICATION"
	  application "$appconfigname"
       }

       Application properties, like Amanda configuration parameters, are insensitive to case, and - (dash) and _ (underscore) may be used
       interchangeably.

       See the individual plugin documentation for properties applicable to each plugin.
