RE: network backups with tar



I am not sure if this helps any or has been answered before but here
goes:
Create a keypair 'ssh-keygen' as root on the machine you are running the
tar command on. Then place the public part of the keypair, i.e.
id_dsa.pub, in the file /root/.ssh/authorized_keys2 on the target
machine. You can ssh to the target machine without having to supply a
password. See the man pages for 'ssh' 'ssh-keygen' paying special
attention to the permissions required on the ~/.ssh directories on both
machines. With publc/privated keypairs properly setup you can securely
ssh to any machine without passwords..even to running Xwindows
applications over a secure connection.
