We have Excelan networking software running on several machines with SCO Xenix. I want to back up from one machine to another that has an exabyte. To do this I use: rsh Miranda "tar cf - /" | dd of=/dev/exab0 ibs=1 obs=1024 This is all fine and dandy except it is very,very slow. We tracked the slowness to dd. So if we could find another program that will format a block to tape. I cannot find one. If tar read from stdio, we could do it that way, but it don't. Now, if I had the source code to tar then it would read from stdio. I can program. So this is my request: Either a copy of the source code to tar or a way to back up using tcpip without using dd.

This version of tar does a real good job. Another archive program is pax. It was posted to comp.sources.unix or comp.sources.misc. I can't remember which. Hope this helps. -- -------------------------------------------------------------------------------- Terry Klarich <klarich@d.cs.okstate.edu> n5hts
