Advanced Maryland Automatic Network Disk Archiver (Server)

Amanda is a backup system designed to archive many computers on a network to a single large-capacity tape drive. This package is suitable for large amounts of data to backup. For smaller solutions take a look at afbackup, tob, ...

 Features:
  * will back up multiple machines in parallel to a holding disk, blasting
    finished dumps one by one to tape as fast as they can be written to
    tape.  For example, a ~2 Gb 8mm tape on a ~240K/s interface to a host
    with a large holding disk can be filled by Amanda in under 4 hours.
  * built on top of standard backup software: Unix dump/restore, and
    later GNU Tar and others.
  * does simple tape management: will not overwrite the wrong tape.
  * supports tape changers via a generic interface.  Easily customizable
    to any type of tape carousel, robot, or stacker that can be controlled
    via the unix command line.
  * for a restore, tells you what tapes you need, and finds the proper
    backup image on the tape for you.
  * recovers gracefully from errors, including down or hung machines.
  * reports results, including all errors in detail, in email to operators.
  * will dynamically adjust backup schedule to keep within constraints:
    no more juggling by hand when adding disks and computers to network.
  * includes a pre-run checker program, that conducts sanity checks on both
    the tape server host and all the client hosts (in parallel), and will
    send an e-mail report of any problems that could cause the backups to
    fail.
  * can compress dumps before sending or after sending over the net, with
    either compress or gzip.
  * can optionally synchronize with external backups, for those large
    timesharing computers where you want to do full dumps when the system
    is down in single-user mode (since BSD dump is not reliable on active
    filesystems): Amanda will still do your daily dumps.
  * lots of other options; Amanda is very configurable.

For important notes, see /usr/share/doc/amanda-server/README.Debian.

Explanation of suggested programs:

 - perl is needed for some non essential server utilities
 - gnuplot is needed for plotting statistics of backups
 - to backup the tape server, you need to install the client too
