automatic backup to external server

yes i read,

 

 

but the connection ssh from the remote backup server to BIG IP doesn't work.

 

I put the server's public key in the directory of the user .ssh/authorized_key

 

and when i do : sh run sshd

 

i have this :

 

sys sshd {

 

include "AuthorizedKeysFile %h/.ssh/authorized_keys"

 

}

 

 

Should i do something else to make it work ?

 

 

thanks,
