This is just as expected. You just copied the amanda header over,
you still need to loop over all the other files too.
Each DLE is put as a separate file on tape. The very first file
on tape is the tape header. You can read each tape using the
non-rewinding device and keep on reading with dd.
Something (untested) like this would work (asuming /dev/nrsa* is
the nonrewindig device on your OS):
while dd bs=32k if=/dev/nrsa1 of=tmp-file
do dd bs=32k if=tmp-file of=/dev/nrsa0
echo =======
done; rm tmp-file
And you have to verify if the blockcounts that get written to tape
match up with the counts from the previous reads.
[15:46:05]root@anubis:/local0/tmp# amrestore /dev/rsa1
I believe you think that the first argument is the tapedevice. No.
The tapedevice can be optionally specified after the -h option.
The first non-option arg of amrestore is the hostname you want to
restore (default, all dle's for that hostname).
Could I use amrestore -r and then dd the raw output onto the new tape?
Thanks for any ideas/assistance that anybody can provide!
Just like above, but then you'll need much more diskspace.
