Replicating files between servers.

cpgeorge · 12-08-2004, 04:30 PM

I hope this is not a stupid question, I am still early in the learning stage. I am looking for advice on how to replicate files on a daily basis from SYSTEM A (Fedora core 2) to SYSTEM B (Red Hat 9). They are both on the same subnet and behind a firewall so security is not a high priority. I am just needing an easy, automated way to update some files on SYSTEM B with files from SYSTEM A daily. Thanks for any help anyone can provide.

Rsync over ssh:

Code:

#rsync -e ssh -avzp --delete [/SYSTEM_A/dir] username_on_SYSTEM_B@SYSTEM_B:[/SYSTEM_B/dir]

Howto

I think this is going to do the trick but I am running into another problem. We use a non standard port for SSH. When I use /usr/bin/rsync -e ssh -pXXXX -avzp /path/* server:/path/ I get the messege that rsync: -pXXXX: unknown option. How can I tell rsync that it needs to use a port other then port 22 when it sync's up?

Thanks for any additional help.

well the rsync manpage says to use the --port option to set the rsyncd port, but i would assume this would be the ssh port if it's over ssh.

no, scratch that...

rsync -e 'ssh -p1234' ...

Thanks a lot. I got it to work. One day hopefully I will get to the point that I can start answering peoples questions :-).

O.k. it works when I run it manually and can type the password in, but how to I get it to use the password when running from a cron? Again-- security is not a high priority-- both systems are on the same subnet and behind a firewall.

Here is what I am using.

/usr/bin/rsync -e 'ssh -pXXXX -l nabu' -avzp /named/RBL/* XXX.XXX.XXX.XXX:/named/RBL/

Thanks again for all your help
