Sotto GNU/Linux esistono da anni programmi che possono essere utilizzati con successo come strumenti per il backup come ad esempio tar oppure dump. Quando però le esigenze si complicano un po' ecco allora che c'è bisogno di strumenti più complessi e completi. Uno dei più popolari programmi per il backup è certamente Amanda.

Amanda is a client/server application for making remote backups. While originating from a UNIX environment, it also supports backups of windows machines (via the smbclient utility). Client software for other machines is planned. See the Amanda homepage for details.The Amanda CDRW-Taper is a drop-in replacement for the taper component of the Amanda backup system. CDRW-Taper makes it possible to dump backups to CD-RW, DVD+RW or DVD-RW instead of tape.

Generalmente no consideramos de importancia o no nos damos el tiempo necesario para prevenir los problemas de un borrado accidental de datos de importancia.

AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that allows the administrator to set up a single master backup server to back up multiple hosts over network to tape drives/changers or disks or optical media. Amanda uses native dump and/or GNU tar facilities and can back up a large number of workstations running multiple versions of Unix. Amanda uses Samba or Cygwin to back up Microsoft Windows desktops and servers. The most recent stable release is version 2.5.2p1, released on June 6, 2007. Download here!
