nfs exports

["Carl Wilhelm Soderstrom" <carls@agritech.com>]

        I wish to export a home directory from one machine, and mount it on
another, for backup purposes. 
        I created the nfs export, it's in /etc/exports, looks right.
        I try mounting it (as root), 'mount -t nfs
xxx.xxx.xxx.xxx:/home/<username> /mnt/<username)'; but it tells me
"permission denied".
        what's going wrong here?

        also, I'm wary of how secure this setup is... i'd rather do it over
SSH or the like. however, I have no idea how SSH works or is set up (am
trying to get around to reading the stuff at ssh.fi).

any advice?

thanks much!
