Topic: can we actually make a mirror server by using Rsync?

[helin16]

hey, guys, I 've actually played with SME for while now, and I wanna to a create mirror server to my old one, performing like a backup but hourly.

but everytime I got my script running, it always ask me to input the password. and My script is like:

Code: [Select]

MASTER="192.168.1.10"
DIR="/"
LDIR="/"
SSH="/usr/bin/ssh"
export RSYNC_PASSWORD=XXXXX
rsync -avrR --links --rsh=$SSH $MASTER:$DIR $LDIR

and also, some part of the files could be backup, anyone can help?

If your doing this over ssh then you can use the concept of an ssh key to take care of business.

The ssh-keygen rsa   or ssh-keygen dsa as the specific user you want to this to work as needs to be executed. Once you have your public and private keys created using that, you need to drop the ssh private key in /home/user/.ssh/authorized-keys

There are plenty of topics on this at google and one in particular that is an ibm white/paper  redbook that shows you step by step.  

Here is a pretty decent one - http://www.securitydocs.com/library/3385

Then you can execute your script and  it will not ask for a pass ( this of course all happens within a secure ssh tunnel...nice!!).

Hope that helps.

thanks a lot, it works!!!!

but there is another problem...after I'v run the script, it's still not a mirror of the original server...how can I mirror these two?
