it's a little bit strange that the local solution is working here with a
cat. Usual you use dd here to connect to the pipe and not cat e.g. like

dd if=<input pipe from DB> bs=32k | gzip -q | dd of=<tape> bs=32k
 
Therefore the solution for a remote tape might be as follows 

dd if=<input pipe from DB> bs=32k | gzip -q | ssh <user>@<host> dd
of=<tape> bs=32k

Please let me know if this works ...
