The '''Advanced Maryland Automatic Network Disk Archiver''' ('''Amanda''') is an open source [[computer]] archiving tool that is able to back up data residing on multiple computers on a [[computer network|network]]. It uses a [[client–server model]], where the server contacts each client to perform a backup at a scheduled time.<ref>{{cite book | first1 = Dmitri | last1 = Joukovski | first2 = Stefan G. | last2 = Weichinge | editor-last1 = Preston | editor-first1 = W.{{nbsp}}Curtis | date = 2007-01-23 | chapter = 4.

Amanda was initially developed at the [[University of Maryland, College Park|University of Maryland]] and is released under a [[BSD License|BSD-style license]].{{r|AmandaLicenses}} Amanda is available both as a free community edition and fully supported enterprise edition. Amanda runs on almost any [[Unix]] or [[Unix-like]] systems. Amanda supports Windows systems using [[Samba software|Samba]] or a native Win32 client with support for open files.<ref>{{cite web | url = https://wiki.zmanda.com/index.php?title=Zmanda_Windows_Client&oldid=8901 | date = 2016-09-01 | title = Zmanda Windows Client | website = [[Zmanda]] | access-date = 2022-12-15 | language = en | archive-url = https://web.archive.org/web/20210927161456/https://wiki.zmanda.com/index.php?title=Zmanda_Windows_Client&oldid=8901 | archive-date = 2021-09-27 | url-status = live | df = dmy-all}}</ref>

Amanda supports both tape-based and disk-based backup, and provides some useful functionality not available in other backup products.  Amanda supports tape-spanning ''i.e.'' if a backup set does not fit in one tape, it will be split into multiple tapes.

==Enterprise edition==
A commercial version of Amanda was developed by the company [[Zmanda]]. It includes a management [[graphical user interface]] (GUI) and other features such as scheduler, plugin framework, and an optional [[Online backup services|cloud backup service]] support. The cloud backup option uses the [[Amazon S3]] service from [[Amazon Web Services]] as the cloud storage provider and enables safe offsite storage of the Amanda backup data. The plugin framework allows for application-specific backups and is used by Amanda Enterprise to support applications such as [[Oracle database]], Samba [[network share]], NDMP, etc. Amanda Enterprise also supports image-level backup of live [[virtual machine]] running on VMware infrastructure.
