Backup and Sync Software

I'm trying to find a good backup software that will allow me to sync to a network share. I have an NTFS RAID1 server that I want to sync my Mac to in real time.
Meaning, it will sync between the volumes I have have on my Mac and the volumes on the server on the fly in both directions in real time.
I found a couple of software that have mixed reviews and I wanted to know if anyone here has any recommendations or experience using these software or other similar ones on Yosemite.

First on is an open-source project called FreeFileSync and the second one is a commercial one that is called "GoodSync Desktop for Mac."

Thank you very much in advance!

 

Awesome! It looks like a solid software and it has most, if not all of the options I'm looking for.
I'll definitely give it a try. Thanks!
