I would like to tar to a tape drive that
is connected to another host.
Can this be accomplished?

Thanks

Hi !

Try it :
find ... | tar cvf - | remsh host "dd of=/dev/rmt/0m obs=10k"

if you are not tied down to using tar, you could use fbackup, as this is designed to do exactly that.
man fbackup

Hi Steve,

The command given by Sandor will work...
providing your systems are properly setup for remote commands.
Make sure that on the remote system (with the tape drive), the /.rhosts file (if you are root) has an entry for the system you're archiving files from.

Best regards,

Dan

PS: the find isn't absolutely necessary, you may use tar 'as-is' like in
tar cvf - file [file|directory] ... | remsh remote_host -n "dd of=/dev/rmt/xxx obs=10K"

Hi,

Try the following:
a. To write remotely on that machines /dev/rmt/0m

tar cv . | remsh dd of=/dev/rmt/0m bs=10k

b. To read remotely on remote's /dev/rmt/0m

remsh dd if=/dev/rmt/0m |tar xvf -

Good Luck

Thanks for the responses, I appreciate it.
I had done the remote fbackup, but the user
in this case has their mind set on tar.

I backup files from my g40 to my L1000 using fbackup from SAM. I have the g40 directory to backup mounted on the L1000 using NFS. In the "Select Backup Scope" screen I select "Cross NFS Mounts - YES", and enter the files I want to backup. For example; I have the /tmp directory from the g40 mounted as /tmp/g40. The entry to backup would then be:
/tmp/g40/.

Hope this helps...RD
