[comp.sys.sun] Backing up UNIX Sys V hosts to central Suns

trw@uunet.uu.net (Trevor Wright) (08/04/89)

Having largely sorted out the centralised backup of our 30 odd Suns onto a
central 8mm video tape, we have now received some requests from users of
UNIX System 5 machines (eg ALTOS, Intergraph) to provide them with a
service.

As far as we can see, Sys 5 does not provide 'rdump'-like facilities, and
its dump command cannot take "host:device" type syntax on the destination
argument.

This must be a common problem - any suggestions please.

The SysV machines should have rcmd, the functional equivalent of the rsh
command. They also have named pipes. Therefore start one job like this:

	cat /dev/rdump.FIFO | rcmd bigsun dd obs=126b of=/dev/rst8

which sucks on the pipe and then sends to dd running on the Sun. Start the
real dump by doing this:

	dump 0ufk /dev/rdump.FIFO 55000 /dev/yourfilesys

Note that the size given dump is suitable for DC600 tapes, change as
needed for your physical devices. I'm actually using this because my tape
drive on a SysV machine is not currently functional.

How about dumping using a remote shell (rsh) and piping to the drive. ie

rsh remote-machine dump 0fu - /dev/filesystem | dd of=/dev/tape-drive bs=....
