AMANDA(8)		System Administration Commands		     AMANDA(8)

       amanda - The Open Source Backup Platform

       This manual page gives an overview of the Amanda commands and
       configuration files for quick reference.

       Here are all the Amanda commands. Each one has its own manual page. See
       them for all the gory details.

       There are four user-editable files that control the behavior of Amanda.

       The first two are amanda.conf(5) and amanda-client.conf(5), the main
       configuration files for the server and client, respectively. They
       contain parameters to customize Amanda for the site.

       Next is the disklist(5) file, which lists hosts and disk partitions to
       back up.

       Last is the seldom-edited tapelist(5) file, which lists tapes that are
       currently active. These files are described in more detail in the
       following sections.

       All files are stored in individual configuration directories, usually
       under /etc/amanda/. A site will often have more than one configuration.
       For example, it might have a normal configuration for everyday backups
       and an archive configuration for infrequent full archival backups. The
       configuration files would be stored under directories
       /etc/amanda/normal/ and /etc/amanda/archive/, respectively. Part of the
       job of an Amanda administrator is to create, populate and maintain
       these directories.

       All log and database files generated by Amanda go in corresponding
       directories somewhere. The exact location is controlled by entries in
       amanda.conf(5). A typical location would be under /var/adm/amanda. For
       the above example, the files might go in /var/adm/amanda/normal/ and

       As log files are no longer needed (no longer contain relevant
       information), Amanda cycles them out in various ways, depending on the
       type of file.

       Detailed information about amdump runs are stored in dump logs -- files
       named amdump.NN where NN is a sequence number, with 1 being the most
       recent file.  Amdump rotates these files each run, keeping roughly the
       last tapecycle (see below) worth of them.

       The file used by amreport to generate the mail summary is the trace
       log. This file constitutes the "catalog" describing the data on the
       tapes written in a run. It is named log.YYYYMMDDHHMMSS.NN where
       YYYYMMDDHHMMSS is the datestamp of the start of the amdump or amflush
       run and NN is a sequence number started at 0. At the end of each amdump
       run, log files for runs whose tapes have been reused are renamed into a
       subdirectory of the main log directory (see the logdir parameter below)
       named oldlog. It is up to the Amanda administrator to remove them from
       this directory when desired.

       Index (backup image catalogue) files older than the full dump matching
       the oldest backup image for a given client and disk are removed by
       amdump at the end of each run.

       For Samba access, Amanda needs a file on the Samba server (which may or
       may not also be the tape server) named /etc/amandapass with share
       names, (clear text) passwords and (optional) domain names, in that
       order, one per line, whitespace separated. By default, the user used to
       connect to the PC is the same for all PC´s and is compiled into Amanda.
       It may be changed on a host by host basis by listing it first in the
       password field followed by a percent sign and then the password. For
	 //some-pc/home normalpw
	 //another-pc/disk otheruser%otherpw

       With clear text passwords, this file should obviously be tightly
       protected. It only needs to be readable by the Amanda-user on the Samba

       All host and disk arguments to programs are special expressions. The
       command applies to all disks that match your arguments. This section
       describes the matcher.

       The matcher matches by word, each word is a glob expression, words are
       separated by the separator ´.´ for host and ´/´ for disk. You can
       anchor the expression at left with a ´^´. You can anchor the expression
       at right with a ´$´. The matcher is case insensitive for host but is
       case sensitive for disk. A match succeeds if all words in your
       expression match contiguous words in the host or disk.

       dot (.)
	   word separator for a host

	   word separator for a disk

	   anchor at left

	   anchor at right

	   match exactly one character except the separator

	   match zero or more characters except the separator

	   match zero or more characters including the separator

       Some examples:

	   Will match hosta,, and hoSTA.dOMAIna.ORG but not

	   Will match host but not hosta.

	   Will match hosta and hostb, but not host.

	   Will match hoina but not

	   Will match hoina and

	   Will match hosta but not

	   Will match /dev/sda1 and /dev/sda12.

	   Will match the disk opt but not the host opt.

       (note dots:) .opt.
	   Will match the host opt but not the disk opt.

	   Will match the disk / but no other disk.

	   Will match the disks /usr and /usr/local.

	   Will match the disks /usr but not /usr/local.

       A datestamp expression is a range expression where we only match the
       prefix. Leading ^ is removed. Trailing $ forces an exact match.

	   match all dates beginning with 20001212, 20001213 or 20001214

	   same as previous

	   match all dates between 20001212 and 20001224

	   match all dates that start with 2000121 (20001210-20001219)

	   match all dates that start with 2 (20000101-29991231)

	   match all dates between 20000101-20101231

	   match only 200010

       A dump specification selects one or more dumps. It has the form
       [host][:disk][@datestamp], where each component is a pattern as
       described above. If a component is missing, it is treated as a
       wildcard. The characters ´:´, ´@´, and ´\´ may be escaped within any
       component by preceding them with a ´\´.

       Some examples:

	   all dumps of client17

	   All dumps on with datestamps matching 20080615

	   All dumps of /var/www on host webserver

	   The dump of webserver with datestamp 200806150317

	   All dumps of /var/www on any host

       Most commands allow the override of specific configuration options on
       the command line, using the -o option. This option has the form
       -oname=value. An optional space is allowed after the -o. Each
       configuration option should be specified in a separate command-line

       For global options, name is simply the name of the option, e.g.,

       amdump -oruntapes=2
       For options in a named section of the configuration, name has the form
       SECTION:section_name:name, where SECTION is one of TAPETYPE, DUMPTYPE,
       HOLDINGDISK, or INTERFACE, and section_name is the name of the
       tapetype, dumptype, holdingdisk, or interface. Examples:

       amdump -o TAPETYPE:HP-DAT:length=2000m
       amdump -o DUMPTYPE:no-compress:compress="server fast"
       amdump -o HOLDINGDISK:hd1:use="-100 mb"
       amdump -o INTERFACE:local:use="2000 kbps"

       When overriding device properties, one must carefully quote the command
       line to simulate the syntax of real configuration files. The following
       example should serve as a guide:

       amdump -o ´device-property="PROPERTY_MAX_VOLUME_USAGE" "100000"´

       Note that configuration overrides are not effective for tape changers,
       which supply a tapedev based on their own configuration. In order to
       override tapedev, you must also disable any changer:

       amdump -otapedev=/dev/nst1 -otpchanger=´´
