Does anyone know if apollo ever plan to support the standard (?)
remote dump and remote restore (rdump and rrestore)?
I ask because under sr10.1 there is a manual page for rmt
(remote magtape protocol module), but no executable, and
rmt is a key element when using rdump and rrestore.

There are two issues here: remote tape use and a dump facility to use remote tapes. The remote tape issue is pretty easy to resolve if you have source to 4.3 BSD. /etc/rmt compiles without any problems. I use rmt to use the the Apollo tape drive from my Mac running A/UX. For remote dumps, you can use tar or cpio piped into an rsh dd or you could try to port a version of tar that supports remote tapes (there a remote tape liblrary posted to the net years ago). If you want to use rbak/wbak, you'd have to wait for Apollo to support remote tapes. If you want to port the BSD dump/restore (rdump/rrestore), quit now while you're still ahead. Dump works by opening the raw device for the filesystem and reading the file system disk structures (inodes, super blocks, cylinder groups, etc) directly. To port this to Apollo's disk structures would be basically a complete re-write. -- Charles. {sun, ucbvax, pyramid, uunet}!unisoft!cander

I am currently running a PD rmt library on our SR10.1 nodes, DN4000 & DN10000. With the new versions of wbak/rbak there is a option to write stdout and read stdin. I have combinded these options with a little cat-like routine using the rmt library to dump 8mm tapes on our Suns from the Apollo. I explained the complete system about a month ago in this newsgroup. -- Alan Bair SPS CAD Logic Simulation & Test Motorola, Inc. Austin, Texas ...!cs.utexas.edu!oakhill!turbinia!abair
