AMDUMP(8) System Administration Commands AMDUMP(8) NAME
amdump - back up all disks in an Amanda configuration SYNOPSIS
amdump [--no-taper] [-o configoption...] config [host [disk...]...] DESCRIPTION
Amdump is the main interface to the Amanda backup process. It loads the specified configuration and attempts to back up every disk specified by the disklist(5). Amdump is normally run by cron. The command optionally takes a set of DLE specifications (see amanda-match(7)) to narrow the DLEs that will be dumped. All disks are dumped if no expressions are given. If a file named hold exists in the configuration directory, amdump will wait until it is removed before starting the backups. This allows scheduled backups to be delayed when circumstances warrant, for example, if the tape device is being used for some other purpose. While waiting, amdump checks for the hold file every minute. In some cases it is desirable to dump all Amanda clients to holding disk without writing anything to storage media. The --no-taper option instructs Amanda to not start the taper, and thus enter degraded mode immediately. See the amanda(8) man page for more details about Amanda. OPTIONS
host [disk]* Specify the host and disk on which the command will work -- see the description of DLE specifications in amanda-match(7). -o configoption See the "CONFIGURATION OVERRIDE" section in amanda(8). EXAMPLE
Here is a typical crontab entry. It runs amdump every weeknight at 1 a.m. as user bin: 0 1 * * 1-5 bin /usr/local/sbin/amdump daily Please see the crontab(5) or crontab(1) manual page for the correct crontab format for your system. MESSAGES
amdump: waiting for hold file to be removed The "hold" file exists and amdump is waiting for it to be removed before starting backups. amdump: amdump or amflush is already running, or you must run amcleanup Amdump detected another amdump or amflush running, or the remains of a previous incomplete amdump or amflush run. This run is terminated. If the problem is caused by the remains of a previous run, you must execute amcleanup(8) and then rerun amdump. EXIT CODE
The exit code of amdump is the ORed value of: 0 = success 1 = error 2 = a dle give strange message 4 = a dle failed 8 = Don't know the status of a dle (RESULT_MISSING in the report) 16 = tape error or no more tape SEE ALSO

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 configuration 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. Most Amanda applications take a "config" parameter; this is generally the (unqualified) name of the configuration directory, e.g., normal. If the parameter is . (dot), the current directory is used. This feature is present for backward compatibility, but is not commonly used. Configuration Override 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 option. 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='' AUTHORS
