[dd] bs=blocksize doesn&#39;t work as expected, for example:<br>tar -c /somedir | dd bs=256K of=/dev/nst0<br>In this example backup record will be recorded to a tape with block size = 10K instead of 256K because 10K is default for tar.<br>
There is workaround:<br>tar -c /somedir | dd ibs=256K obs=256K of=/dev/nst0<br>If we set block size for input and output separatly - it works as expected.<br><br><a class="resultlink" href="http://packages.ubuntu.com/lucid/coreutils">lucid</a> (utils):
