Description:
Amanda is a backup system designed to archive many computers on a
network to a single large-capacity tape drive. This release is
currently in daily use at the University of Maryland at College Park
Computer Science Department, backing up all the disks on all the
workstations in the department: currently over 70 gigabytes of data
across more than 400 filesystems on more than 146 workstations and
servers, using a single 5 Gigabyte Exabyte EXB-8500. Here are some
features of Amanda:
* written in C, freely distributable.
* built on top of standard backup software: BSD Unix dump/restore, and
later GNU Tar and others.
* will back up multiple machines in parallel to a holding disk, blasting
finished dumps one by one to tape as fast as we can write files 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.
* 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.
* supports Kerberos 4 security, including encrypted dumps. The Kerberos
support is available as a separate add-on package, see the file
KERBEROS.HOW-TO-GET on the ftp site, and the file docs/KERBEROS in this
package, for more details.
* 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 over net, with either compress
or gzip.
* can optionally syncronize 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.

distribution.
Advertised architectures:
Amanda should run on any modern Unix system that supports dump,
has sockets and inetd, and either system V shared memory, or BSD
mmap implemented.
In particular, Amanda 2.3.0 has been compiled, and the client side
tested on the following systems:
IRIX 5.2 SunOS 4.1.X (X >= 1)
SunOS 5.5 BSDI BSD/OS 2.1
Ultrix 4.2 NetBSD 1.0
DEC OSF/1 3.2 AIX 3.2
HP-UX 9.X HP-UX 10.X (X >= 01)
The Amanda 2.3.0 server side is known to run on SunOS 4.1.3 and
Solaris 2.5 machines, but it also compile on all of the other
machines and there is no reason at this time to believe that it
will not work.
