Incremental Changes between two or more servers
Scenario :
Have 3+ server when i make changes in server 1 and within a time frame or so the other server has the same changes made / new files.
I looked at RSYNC but couldnt get much info about how should i do.
If anyone can shed some light on this, it will be much appreciated.
Thank you.

In this scenario are you using one master and pushing changes to slaves? If yes, then harness your inner Google-fu and look into more examples of rsync.
Unison. Bit torrent sync. Syncthing.
+1 for Syncthing.
It's not clear if it's just files you want copied, or commands run as well. If the latter, look into configuration management tools. If you can't figure out how to use those tools (or rsync itself) hire someone who can either teach it to you or do it all for you.
syncthing, lsyncd are 2 such things that will automatically sync/push changes.
There are many others depending on how you want it to sync and if you want it to be automatic or manually initiated
thanks everyone syncthing is what I was really looking for.
rsync can sync any files with deltas, e.g.
rsync -avz -e ssh [directory] [email protected]:[directory]I have a project I've been working on that requires 10 servers in different datacenters to be in sync. I'm using csync and it's pretty great.
Thanks Zack for mentioning csync. I have used it in past and its great tool for doing file sync between 3 servers and more. But i am looking for database sync too and csync corrupts db on the test I done. Any idea with that ?
And how you sync 10 at once ?
The best thing I can think of is a Galera cluster, however I've never used Galera across more than one DC.
