What is this error? This rdiff-backup command is run in a shell script. How to resolve this issue?

         ssh -l root 161.3.46.12 rdiff-backup [email protected]::/root/files/1/ /root/cloodon_sync
        spawn ssh -l root 161.3.46.12 rdiff-backup [email protected]::/root/files/1/ /root/cloodon_sync
        [email protected]'s password: 
        Host key verification failed.
        Fatal Error: Truncated header string (problem probably originated remotely)

        Couldn't start up the remote connection by executing

            ssh -C [email protected] rdiff-backup --server

        Remember that, under the default settings, rdiff-backup must be
        installed in the PATH on the remote system.  See the man page for more
        information on this.  This message may also be displayed if the remote
        version of rdiff-backup is quite different from the local version (1.0.5).

In /etc/vimrc, how do I disable the ctrl-v feature. I.e, disable visual block.

 <created>
  [email protected] 
</created>

I want to replace the above with but the username may vary i.e,[email protected] ,[email protected]...

  <created>
   [email protected]
  </created>

What is the command to replace this in vim

 %s/<created>\r*\r</created>/new string

Does ssh-keygen -t rsa work if only set for root user

i.e, if the username on local system is sodium and i generate the key using the above said command and on the remote system if i place the key in /root/.ssh authorized_keys ,this works.

But on the remote system if the key is placed in /home/natrium/.ssh authorized_keys

This still prompts for a password.Is this the expected behavior or is that some thing wrong in the above procedure

Thanks..

Let say i have a source directory which contains The contents /foo/a /foo/b(These are the files in a directory on a remote system)

using rdiff command i make a backup as

 rdiff-backup [email protected]::/foo backups

And a,b are now present in my backups directory.And then i delete file a from the remote system and again i do a sync so my local directory has the file b only.

My question is that how do i restore file a if the deletion and sync is done on the same day

Thanks..
