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 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.
