Thanks for all the help, but I have a problem to restore the files.
When I type:
root@ # dd if=/dev/rmt/0n ibs=64k | ufsrestore if -
I recieve the following error message:
read: Invalid argument
0+0 records in
0+0 records out
Volume is not in dump format
But as far as I know it should be in a dump format!!! ? because in the Amanda.conf I defined the backup as: define dumptype daily { global # program "DUMP" # the default # record yes # the default
comment "daily" compress client fast priority high # dumpcycle 5 # should be obtained from dumpcycle above index yes }
I also tried the following:
% mt -f /dev/rmt/0n rewind
% dd if=/dev/rmt/0n of=/tmp/data bs=64k count=2
% od -c /tmp/data | head
And received the following output:
0000000 \0 002 P 022 \0 \f \0 001 . \0 \0 \0 \0 003 242 Q
0000020 \0 \f \0 002 . . \0 \0 \0 002 P 023 001 350 \0 006
0000040 n e w b c k \0 \0 \0 \f \0 003 b c k \0
0000060 \0 \0 \0 \0 001 320 \0 006 n e w b c k \0 \0
0000100 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0
*
0001000
Can one deduct the dump format from the above
output?
Many thanks,

Then you understand that you can replace "amrestore" with a
"mt" and "dd".

mt -f /dev/rmt/0n fsf 34
dd
bs=32k if=/dev/rmt/0n skip=1 of=/some/where
dd to to stdout, in a pipe with netcat:
... | nc -w 1 client 1234
And on the client you have already this command listening:
nc -l -p 1234 | gtar -zxpGvf -
The docs in http://www.amanda.org/docs/restore.html
are a little more expanded, giving more examples in:
http://wiki.zmanda.com/index.php/Restoring_files
Easiest is to first restore the amanda command "amrestore"
That one does not need any config file at all.
