tar to remote tape without password prompt

mnauta · 06-13-2011, 03:27 PM

I need backup files to a tape drive on a remote server without being prompted for password.

I got the part working to tar files to the remote tape drive like this:

Code:

tar czfv - /data/home/users/manuel/Volunteer | ssh user@192.x.x.x "cat > /dev/st0"

currently I got rsync to work with out being prompted for password like this:

Code:

rsync -aqH --delete -e "ssh -i /root/rsync-key" /var/opt/ user@192.x.x.x:/var/opt

How can I get the above tar command to work like the rsync command so it does not prompt me for a password.

Same idea. Just provide the Identity file to ssh(1) in your pipeline.

I am having problems placing it in the right spot. Where should it go?

It's an option to ssh(1), so it should follow...

Code:

ssh -i ...
