It doesn't exist a best tecnique or policy about how to backup your data in Linux. It depends how are your data and if you want backup them locally or in remote. There are some mature tools for specific tasks and you have to decide with one suits better. There are some GUIs that simplify the job, but in case of issues, the terminal is the ONLY way to debug what is happening.

Areca is a personal file backup software developed in Java. It allows you to select files or directories to back up, filter, encrypt and compress their content, and store them on your backup location. Areca supports incremental backups and generates backup reports, which can be stored on your disk or sent by email. This guide explains how to install and use it on a Fedora 9 desktop (GNOME).

NetBackup can run several restores at the same time from a single multiplexed tape. This is done by means of theMPX_RESTORE_DELAY option, which specifies how long, in seconds, the server waits for additional restore requests of files or raw partitions that are in a set of multiplexed images on the same tape. The restore requests received within thisperiod are executed simultaneously. By default, the delay is 30 seconds.

Sitback is actual just another tar/gzip interface. It evolved from a bash-script I wrote to handle automated backup's on Linux fileservers.The script worked ok, but it soon proved difficult and tiresome to make local modifications to the script to handle various problems or differences.

KaTeker is a backup tool for Linux useful for small companies and private people.It saves data onto hard disks and CDs, DVDs or other random access media.Actual version 0.95 change logrelease is Alpha.KaTeker is designed to manage the backup of data of daily work.

Nautilus, come Kommander per KDE, è un ottimo File Manager. A volte però può risultare un po lento e pesante. Se volete alleggerire il vostro sistema o se siete semplicemente stanchi di Nautilus e volete provare qualche File Manager alternativo, beh, PCMan può fare al caso vostro. Gli utenti Gnu/Linux dispongono di un infinità di File Manager leggeri, alcuni però, come ROX-filer sono un po’ scomodi da usare, altri invece, come Thunar di Xfce, non dispongono di funzioni importanti come la navigazione a schede. PCMan è al tempo stesso leggero e completo.

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.

Bastrama is a command-line tool to manage backup files that are stored on random access memory (e.g. hard drives).It implements an infinite grandfather-father-son strategy by deleting a defined subset of the backup files, therefore saving storage space while still keeping some of the older backups in case something went wrong (and needs to be restored from) a long time ago.

DIBS is a backup system that protects your data by giving your files to peers (and in return, you store their files) so that if a catastrophe strikes your area, you can recover data from surviving peers.This solves the problem of mirroring your data by adding more disks to your own computer only ot have a fire, flood, power surge, etc. wiping out your local data center.Note that DIBS is a backup system, *not* a file sharing system like Napster, Gnutella, Kazaa, etc. In fact, DIBS encrypts all data transmissions so that the peers you trade files with can not access your data.

Dump è una semplice ma anche potente utility per il backup in Linux. Dump esamina i file in un filesystem, e determina quali sono i componenti a rischio stratificando il backup dei files in base alla sua importanza, da cima in fondo. Consente il backup incrementale e può essere controllato attraverso PServer. Come tanti altri programmi per Linux è un progetto SourceForge.net Repository CVS.
