I have the same problem, except compounded. I get multiple
occurrences of
same. I am trying to backup NT SMB shares using samba. My command
is -
((smbclient "\\\\${WS_NAME}\\${WS_NAME}_bu_c" ${PASSWORD} -U
${USER_NAME} \
-N -d0 -Tc -) | gzip > ${TAPE_DRIVE}) > ${NAME} 2>&1
The tape drive is and Exabyte Eliant. mt shows the blocking
factor as 0,
witch I think means is should adapt. I also thought the Exabyte
tapes had an
internal buffer and did their own blocking (=> 1 helical scan?)
from that
buffer.
Any help appreciated.
