We use rdump to back up 30-40 RTs and Suns on our network using one Exabyte
tape drive with the driver supported by Delta Microsystems.  We get about 
180 kilobytes per second over the network using dump/rdump.  Sun does have
a driver for the Exabyte tape unit, but it is not as fast as the Delta
Microsystems one.
