Hi.
I'm looking for a Syncronizacion Softwares (running as a daemon) to do a unidirectional syncronization of some files/folders from a lot of servers to one central server.

As there are a lot of servers i want a software that only needs to be installed on the central server and pulls the files/folders from the other servers.

rsync and unison need to be installed on both machines and syncronize the files/folder by sending them from al the servers to the central server(its no the central server the one who pulls the files/folder from the other servers), so they dont work for what i want.

¿Do anyone know any other?

Thanks in advance.

Bye!


PD: Sorry for my poor English.

rsync may already be installed on all your servers as it is a fairly basic utility in Linux.

If you can't use that then it seems you'd be stuck trying to script something with scp (assuming you have ssh/scp access to the servers). It is not designed for checking whether things already exist though like rsync and unison do so it will eat up your bandwidth.

One way around that might be to run an ssh command to get simply a listing of the files on the remote host with key attributes then do a listing on the master (local) host and diff the two lists to get a list of files to scp from remote to local. This would be somewhat convoluted and unnecessary if you can use rsync. If it were me I'd work out installing rsync to save time.

Yes, I think rsync is the best way for that.

Hi.
A user from another forum (HROAdmin26) give me the answer. I can use rsync in both directions (to send or tu pull):

Right - but it still requires rsync to exists on both hosts. In your original post you implied that rsync doesn't exist on the remote hosts and in my reply I suggested that it probably does.
