Amanda is a backup system designed to archive many -computers on a network to a single large-capacity tape drive. - -Here are some features of Amanda: - - * written in C, freely distributable. - * built on top of standard backup software: Unix dump/restore, 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. - * 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. - - -WHAT ARE THE SYSTEM REQUIREMENTS FOR AMANDA? --------------------------------------------- - -Amanda requires a host that is mostly idle during the time backups are -done, with a large capacity tape drive (e.g. an EXABYTE, DAT or DLT tape). -This becomes the "tape server host". All the computers you are going to dump -are the "backup client hosts". The server host can also be a client host. - -Amanda works best with one or more large "holding disk" partitions on the -server host available to it for buffering dumps before writing to tape. -The holding disk allows Amanda to run backups in parallel to the disk, only -writing them to tape when the backup is finished. Note that the holding -disk is not required: without it Amanda will run backups sequentially to -the tape drive. Running it this way kills the great performance, but still -allows you to take advantage of Amanda's other features. - -As a rule of thumb, for best performance the holding disk should be larger -than the dump output from your largest disk partitions. For example, if -you are backing up some full gigabyte disks that compress down to 500 MB, -then you'll want 500 MB on your holding disk. On the other hand, if those -gigabyte drives are partitioned into 500 MB filesystems, they'll probably -compress down to 250 MB and you'll only need that much on your holding -disk. Amanda will perform better with larger holding disks. - -Actually, Amanda will still work if you have full dumps that are larger -than the holding disk: Amanda will send those dumps directly to tape one at -a time. If you have many such dumps you will be limited by the dump speed -of those machines. - -Amanda does not yet support single backup images larger than a tape. - - -WHAT SYSTEMS DOES AMANDA RUN ON? --------------------------------- - -Amanda should run on any modern Unix system that supports dump or GNU -tar, has sockets and inetd, and either system V shared memory, or BSD -mmap implemented. - -In particular, Amanda 2.4.1p1 has been compiled, and the client side tested -on the following systems: - AIX 3.2 and 4.1 - BSDI BSD/OS 2.1 and 3.1 - DEC OSF/1 3.2 and 4.0 - FreeBSD 2.2.5 - IRIX 5.2 and 6.3 - GNU/Linux on x86, alpha, sparc, arm and powerpc - NetBSD 1.0 - Nextstep 3 (*) - OpenBSD 2.5 x86, sparc, etc (ports available) - SunOS 4.1.x (x >= 1) and 5.[567] - Ultrix 4.2 - HP-UX 9.x and 10.x (x >= 01) - -The Amanda 2.4.1p1 server side is known to run on all of the other -machines except on those marked with an asterisk. - -If you know of any system that is not listed here on which amanda -builds successfully, either client&server or client-only, please -report to amanda-hackers@amanda.org. - - -WHERE DO I GET AMANDA? ----------------------- - -There are several versions of Amanda. The latest version at the time -of this writing is available at: - - ftp://ftp.amanda.org/pub/amanda - - -HOW DO I GET AMANDA UP AND RUNNING? ------------------------------------ - -Read the file docs/INSTALL. There are a variety of steps, from compiling -Amanda to installing it on the tape server host and the client machines. - docs/INSTALL contains general installation instructions. - docs/SYSTEM.NOTES contains system-specific information. - docs/FAQ contains answers to frequently asked questions. - docs/KERBEROS explains installation under Kerberos 4. - docs/TAPE.CHANGERS explains how to customize the changer interface. - docs/WHATS.NEW details new features. - - -WHO DO I TALK TO IF I HAVE A PROBLEM? -------------------------------------- - -Amanda is completely unsupported and made available as-is.
