I wanted to know if there is a way of duplicating tapes across a
network.
Say I have a machine A with a 5 G.B tape drive and another machine
B with the same type of tape drive ...can i somehow duplicate the
tape from a to B ...
I tried
On A
dd if=/dev/rmt0 bs=102 ¦ dd of=B:/dev/rmt0 bs=1024
I also tried to pipe it through rcp....
---------- ---------- ---------- --------- ---------- ----------
A: I created a tar archive to tape with a block size of 1024. I then
used the following command to copy the tape to a remote tape drive:
dd if=/dev/rmtX ibs=1024 obs=512 | rsh $HOST 'dd of=/dev/rmtXX
ibs=512 obs=1024'
where | is the pipe symbol and ' is a single quote. This is a single
command and should be entered on one line. In testing this, I was
required to specify an input block size (ibs) and an output block size
(obs) or it would not work correctly. On the left side of the pipe,
the ibs should be set to the block size that the source tape was
written. The obs should be set to no greater than 512. Larger output
block sizes also caused problems. On the right of the pipe, ibs will
be equal to 512 and obs is the block size that you would like the
target tape to be written.
You will have to create a ./.rhosts file to use the rsh command. This
is documented in InfoExplorer under the rsh command.
