Amanda Network Backup – Open Source Backup for Linux, Windows, UNIX and OS X

AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that allows the administrator of a LAN to set up a single master backup server to back up multiple hosts to a single large capacity tape or disk drive. Amanda uses native tools (such as GNUtar, dump) for backup and can back up a large number of workstations running multiple versions of Unix/Mac OS X/Linux/Windows.


Amanda uses a native Windows client to back up Microsoft Windows desktops and servers.

Features of Amanda:

* Written in C and Perl.

* Built on top of standard backup software: Unix dump/restore, GNU
Tar and other archival tools. It is extensible to support new
archival applications.

* Open file and tape formats. If necessary, you can use standard
tools like mt and GNU Tar to recover data.

* Backs up 32 and 64 bit Windows machines.

* Will back up multiple machines in parallel to a holding disk. Once
a dump is complete, Amanda will copy finished dumps one by one to
virtual tape on a disk or tape as fast as it can.

* Maintains a catalog of files being backed up and their location on
the media.

* For a restore, tells you what tapes you need, and finds the proper
backup image on the tape for you.

* Supports tape changers via a generic interface.  Easily
customizable to any type of tape library, carousel, robot,
stacker, or virtual tape that can be controlled via the unix
command line.

* Supports secure communication between server and client using
OpenSSH, allowing secure backup of machines in a DMZ or out in the

* Can encrypt backup archives on Amanda client or on Amanda server
using GPG or any encryption program.

* Can compress backup archives before sending or after sending over
the network, with compress, gzip or a custom program.

* Many more
