Csync2 is a cluster synchronization tool. It can be used to keep files on multiple hosts in a cluster in sync. Csync2 can handle complex setups with much more than just 2 hosts, handle file deletions and can detect conflicts.
It is expedient for HA-clusters, HPC-clusters, COWs and server farms. If you are looking for a tool to sync your laptop with your workstation, you better have a look at Unison (http://www.cis.upenn.edu/~bcpierce/unison/) too.
The csync2 git tree can be found at https://github.com/LINBIT/csync2/.
You should definitely read the documentation before trying to setup csync2,
