SGI Freeware: amanda 2.4.2p2
amanda-2.4.2p2: description + notes
This is a release of Amanda,
the Advanced Maryland Automatic Network Disk Archiver. Amanda is a backup
system designed to archive many computers on a network to a single
large-capacity tape drive. Amanda uses native dump and/or GNU tar
facilities and can back up a large number of workstations running
multiple versions of UNIX. Recent versions can also use SAMBA to
back up Microsoft Windows 95/NT hosts.
Here are some features of Amanda:
- 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.
- 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.
- 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.
You will need to setup your Amanda configuration before it can be
used: see /usr/freeware/doc/amanda/INSTALL for
directions. You can skip the first section, as Amanda is already
built. The amanda man page documents the default parameters used.
If you intend to setup an "amanda" user account you should
install the fw_amanda.sw_amanda subsystems rather than the
default fw_amanda.sw files. Both sets have the Samba 2.0.6
error message and advfs file system patches applied.
To auto-install this package, go back and click on the respective install icon.
