AMDD(8) System Manager's Manual AMDD(8)NAME
amdd - Amanda version of dd
SYNOPSIS
amdd [ -d ] [ if=input ] [ of=output ] [ bs=blocksize ] [ skip=count ] [ count=count ]
DESCRIPTION
Amdd provides just enough of the standard dd command for the needs of Amanda. This is handy when doing a full restore and the standard dd
program has not yet been found.
Amdd also provides access to the Amanda output drivers that support various tape simulations. This may be used for debugging or to convert
from one format to another.
See the amanda(8) man page for more details about Amanda. See the OUTPUT DRIVERS section of amanda(8) for more information on the Amanda
output drivers.
OPTIONS -d Turn on debugging output.
-llength
Set the output length. If the output driver limits the output size, this controls when end of tape will be simulated.
Length may have a multiplier suffix:
k 1024 (Kilobytes)
b 512 (Blocks)
M 1024*1024 (Megabytes)
The default is no multipler (bytes).
if=input
Input to dd. Default is stdin.
of=output
Where to send the output of dd. Default is stdout.
bs=blocksize
Size of each record. Input records smaller than this will not be padded. Output records will be the same size as the corresponding
input record. Default is 512 bytes.
Blocksize may have a multiplier suffix:
k 1024 (Kilobytes)
b 512 (Blocks)
M 1024*1024 (Megabytes)
The default is no multipler (bytes).
count=count
Number of records to copy. Default is all records until end of file.
skip=count
Number of records to skip before copying input to output. Default is zero.

AMLABEL(8) System Manager's Manual AMLABEL(8)NAME
amlabel - label an Amanda tape
SYNOPSIS
amlabel [-f] config label [ slot slot ]
DESCRIPTION
All Amanda tapes must be pre-labeled before they are used. Amanda verifies the label in amdump and amflush before writing to make sure the
proper tape is loaded.
Amlabel writes an Amanda label on the tape in the device specified by the amanda.conf file in /etc/amanda/config. Label may be any string
that does not contain whitespace and that matches the amanda.conf labelstr regular expression option. It is up to the system administrator
to define a naming convention.
Amlabel appends the new tape to the tapelist file so it will be used by Amanda before it reuses any other tapes. When you amlabel multiple
tapes, they will be used in the order you amlabel them.
Amlabel will not write the label if the tape contains an active Amanda tape or if the label specified is on an active tape. The -f (force)
flag bypasses these verifications.
An optional slot may be specified after the tape label. If a tape changer is in use, amlabel will label the tape in the specified slot
instead of the currently loaded tape.
See the amanda(8) man page for more details about Amanda.
EXAMPLE
Write an Amanda label with the string "DMP000" on the tape loaded in the device named in the tapedev option in /etc/amanda/Daily-
Set1/amanda.conf:
% amlabel DailySet1 DMP000
Label the tape in slot 3 of the currently configured tape changer with the string "DMP003":
% amlabel DailySet1 DMP003 slot 3
MESSAGES
label label doesn't match labelstr "str"
Label label on the command line does not match the labelstr regular expression str from amanda.conf.
label label already on a tape
Label label is already listed as an active Amanda tape.
no tpchanger specified in "path", so slot command invalid
The command line has the slot parameter but the amanda.conf file in path does not have a tape changer configured.
reading label label, tape is in another amanda configuration
This tape appears to be a valid Amanda tape, but label does not match labelstr for this configuration so it is probably part of a
different Amanda configuration.
reading label label, tape is active
Tape label appears to already be part of this Amanda configuration and active, i.e. has valid data on it.
no label found, are you sure tape is non-rewinding?
While checking that the label was written correctly, amlabel got an error that might be caused by mis-configuring Amanda with a
rewinding tape device name instead of a non-rewinding device name for tape.
