AMANDA Backup System

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 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.

Today’s businesses rarely run on just one operating system. Linux users and administrators often have strong preferences for one distribution over another; web designers might lean towards the Mac; legacy software and hardware can include various UNIX operating systems. Despite the complexity of modern business computing environments, a system administrator is expected to find a reliable backup solution.

Even in the case where users are expected to keep important files on networked resources, for true intellectual data security, desktop machines and laptops will also be backed up. The price of hard disk storage is continuously falling, bringing terabytes of storage within reach, and increasing the amount of data that can potentially be lost. (The amount of data that you have will always expand to fit the storage available; as the golden rule states.) We live in a global and e-commerce economy, where businesses run around the clock and crucial business data changes commensurately.
