Sorry, you are not going to find those commands on HP-UX. HP's answer is to use fbackup which will talk to remote tape drives but it is HP only. You now will need to look at doing it yourself using remsh.

e.g.

find . -print | cpio -ocBv | remsh sunhost dd ibs=5k obs=1000k of=/dev/tape

If you are going over a slow network you may want to add compress/uncompress to your pipeline. You could also use tar or fbackup as your front-end command.

Hi,

Using tar
# tar cvf - /dir_name | remsh hostname dd of=/dev/rmt/0m
or
# remsh "dd if=/dev/rmt/0m bs=10k" | tar xvf -

Using cpio

# find . -depth -xdev | cpio -ovxcB 2>/tmp/err.cpio |remsh hostwithtapedrive -l user "cat - | dd of=/dev/rmt/0m obs=5k"

Hi again:

I suppose I should mention one much faster though not free alternative. You might look into Omniback. You can install it as a 60-day trial. It will allow you to backup many flavors of UNIX, Windows, Novell, and others to tape drives located essentially anywhere on the network.

Hi Sunny,

I believe you should be able to use rdump to backup to your Sun's tape drive. I have done the reverse (ufsdump to a HPUX box) and extracted files (restore) there. You have to set up the "r" security stuff (.rhosts, etc) for this to work.

What was your error?

Which commands? The Question Author mentioned rdump and sam and, AFAIK :-), those *are* on HP-UX.

If by "it is HP only" you mean that fbackup *itself* is HP only and must run on HP-UX, then that is true. But fbackup can make *remote backup* (which is asked here) to a tape drive on a non-HP-UX system, provided that system has the Berkeley standard rmt(1M). For details see the comments on rmt in the fbackup(1M) manual page.

Sunny,

get Gnu's tar, it'll do remote tape writes. It will also handle LARGE files.

for hp:

http://hpux.cs.utah.edu/hppd/hpux/Gnu/tar-1.13.25/

for sun:

http://sunsite.ics.forth.gr/sunsite/gnu/tar/

or better yet (where you select your Solaris OS revision):
http://www.sunfreeware.com/

live free or die
