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.
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
A site will often have more than
For example, it might have a
configuration for everyday backups and an
configuration for infrequent full archival backups.
The configuration files would be stored under directories
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
the current directory is used. This feature is present for backward
compatibility, but is not commonly used.
Most commands allow the override of specific
configuration options on the command line, using the -o option. This option has the form -o
An optional space is allowed after the -o .
Each configuration option should be specified in a separate

section_name is the name of the tapetype, dumptype, holdingdisk, or interface.
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=''
