tar cvf - /dir_name | remsh hostname dd of=/dev/rmt/0m

or

tar cvf - . | remsh hostname dd of=/dev/rmt/0m

which will backup the current directory.
hostname is the hostname of the machine with the drive.

also

remsh "dd if=/dev/rmt/0m bs=10k" | tar xvf -
By default tar uses a blocksize of 10K. The reason is that the
logical record size is 512 and blocking factor is 20 (bydefault).

should work

Hi

U can use thi step

#tar -cvf - / |remsh hostname dd of = ..bs=10K

One more thing U can do like NFS mounting. U can mount the directory which U want to be backed up in to the server which is having DDS drive. Then use a normal tar command.
