Thanks for the answer(s).
I have been able to use dd successfully. So, the problem is with amanda?
But, tapetype cannot get 'expected' properties. So, the problem seems
to be something different.
I am sending amanda.conf and I request your help.

# If amanda cannot find a tape on which to store backups, it will run
# as many backups as it can to the holding disks. In order to save
# space for unattended backups, by default, amanda will only perform
# incremental backups in this case, i.e., it will reserve 100% of the
# holding disk space for the so-called degraded mode backups.
# However, if you specify a different value for the `reserve'
# parameter, amanda will not degrade backups if they will fit in the
# non-reserved portion of the holding disk.
# reserve 30 # percent
# This means save at least 30% of the holding disk space for degraded
# mode backups.

# Amanda needs a few Mb of diskspace for the log and debug files,

# Create an amanda directory under there. You need a separate infofile and
# logdir for each configuration, so create subdirectories for each conf and
# put the files there. Specify the locations below.
# Note that, although the keyword below is infofile, it is only so for
# historic reasons, since now it is supposed to be a directory (unless
# you have selected some database format other than the `text' default)

# tapetypes
# Define the type of tape you use here, and use it in "tapetype"
# above. Some typical types of tapes are included here. The tapetype
# tells amanda how many MB will fit on the tape, how big the filemarks
# are, and how fast the tape device is.
# A filemark is the amount of wasted space every time a tape section
# ends. If you run `make tapetype' in tape-src, you'll get a program
# that generates tapetype entries, but it is slow as hell, use it only
# if you really must and, if you do, make sure you post the data to
# the amanda mailing list, so that others can use what you found out
# by searching the archives.
# For completeness Amanda should calculate the inter-record gaps too,
# but it doesn't. For EXABYTE and DAT tapes this is ok. Anyone using
# 9 tracks for amanda and need IRG calculations? Drop me a note if
# so.
# If you want amanda to print postscript paper tape labels
# add a line after the comment in the tapetype of the form
# lbl-templ "/path/to/postscript/template/label.ps"

# dumptypes
#
# These are referred to by the disklist file. The dumptype specifies
# certain parameters for dumping including:
# auth - authentication scheme to use between server and client.
# Valid values are "bsd" and "krb4". Default: [auth bsd]
# comment - just a comment string
# comprate - set default compression rate. Should be followed by one or
# two numbers, optionally separated by a comma. The 1st is
# the full compression rate; the 2nd is the incremental rate.
# If the second is omitted, it is assumed equal to the first.
# The numbers represent the amount of the original file the
# compressed file is expected to take up.
# Default: [comprate 0.50, 0.50]
# compress - specify compression of the backed up data. Valid values are:
# "none" - don't compress the dump output.
# "client best" - compress on the client using the best (and
# probably slowest) algorithm.
# "client fast" - compress on the client using fast algorithm.
# "server best" - compress on the tape host using the best (and
# probably slowest) algorithm.
# "server fast" - compress on the tape host using a fast
# algorithm. This may be useful when a fast
# tape host is backing up slow clients.
# Default: [compress client fast]
# dumpcycle - set the number of days in the dump cycle, ie, set how often a
# full dump should be performed. Default: from DUMPCYCLE above
# exclude - specify files and directories to be excluded from the dump.
# Useful with gnutar only; silently ignored by dump and samba.
# Valid values are:
# "pattern" - a shell glob pattern defining which files
# to exclude.
# gnutar gets --exclude="pattern"
# list "filename" - a file (on the client!) containing patterns
# re's (1 per line) defining which files to
# exclude.
# gnutar gets --exclude-from="filename"
# Note that the `full pathname' of a file within its
# filesystem starts with `./', because of the way amanda runs
# gnutar: `tar -C $mountpoint -cf - --lots-of-options .' (note
# the final dot!) Thus, if you're backing up `/usr' with a
# diskfile entry like ``host /usr gnutar-root', but you don't
# want to backup /usr/tmp, your exclude list should contain
# the pattern `./tmp', as this is relative to the `/usr' above.
# Please refer to the man-page of gnutar for more information.
# If a relative pathname is specified as the exclude list,
# it is searched from within the directory that is
# going to be backed up.
# Default: include all files
# holdingdisk - should the holding disk be used for this dump.
Useful for
# dumping the holding disk itself. Default: [holdingdisk yes]
# ignore - do not back this filesystem up. Useful for sharing a single
# disklist in several configurations.
# index - keep an index of the files backed up. Default: [index no]
# kencrypt - encrypt the data stream between the client and server.
# Default: [kencrypt no]
# maxdumps - max number of concurrent dumps to run on the client.
# Default: [maxdumps 1]
# priority - priority level of the dump. Valid levels are "low", "medium"
# or "high". These are really only used when Amanda has no
# tape to write to because of some error. In that "degraded
# mode", as many incrementals as will fit on the holding disk
# are done, higher priority first, to insure the important
# disks are at least dumped. Default: [priority medium]
# program - specify the dump system to use. Valid values are "DUMP" and
# "GNUTAR". Default: [program "DUMP"].
# record - record the dump in /etc/dumpdates. Default: [record yes]
# skip-full - skip the disk when a level 0 is due, to allow full backups
# outside Amanda, eg when the machine is in single-user mode.
# skip-incr - skip the disk when the level 0 is NOT due. This is used in
# archive configurations, where only full dumps are done and
# the tapes saved.
# starttime - delay the start of the dump? Default: no delay
# strategy - set the dump strategy. Valid strategies are currently:
# "standard" - the standard one.
# "nofull" - do level 1 dumps every time. This can be used,
# for example, for small root filesystems that
# only change slightly relative to a site-wide
# prototype. Amanda then backs up just the
# changes.
# "noinc" - do level 0 dumps every time.
# Unfortunately, this is not currently
# implemented. Use `dumpcycle 0'
# instead.
# "skip" - skip all dumps. Useful for sharing a single
# disklist in several configurations.
# "incronly" - do only incremental dumps. This is similar
# to strategy 'nofull', but will increase
# the dump level as usual. Full dumps will
# only be performed when an 'amadmin force'
# has been issued
# Default: [strategy standard]
#
# Note that you may specify previously defined dumptypes as a shorthand way
# of defining parameters.
