Sync is a great thing, but it can be your undoing - a corrupted file would be a 'changed' file so the good copy is then over written. A lot of times you can't tell if a file is corrupted until you attempt to open it. This is a downfall of NTFS/FAT32/HFS+/EXT2/3 (not sure about 4). ZFS does a good job with this, but would only be used on a NAS type of setup.
Too bad! ZFS does not apply on Windows system. That's the file system I really want for Windows environment. ReFS is the only solution for Windows system. I will try Windows Server 2012 next month after I return from my vacation.
Well, you know there are other OSes out there besides Windows....some are VERY robust, etc.
You've heard the saying...the right tool for the right job.
If nothing else, go look at my posts about using freeNAS on this thread. It is close to turnkey...OS fits and boots from a USB thumb drive...has ZFS, and everything you'd need.
Good tutorials written/video out there on the site....
A little DIY and learning a new thing...is never a bad thing.
I don't use windows much, unless a tool I need to use requires it...but I figure every OS has its uses....best not to get too dependent on any one, especially one owned by a company that can change its mind, direction or go out of business as your primary OS.
You might get to start familiarizing yourself with Linux or other variants of Unix type OSes....they can really be your friend. Sure there is a learning curve.....but there is always a LC when learning any new, valuable skill, no?

I used to use Linux system and built FreeNAS years ago. However, Windows systems are very stable nowadays. Now what I am looking for is a compromised solution between performance, simple, and few machines. What I might going to do later is building a Windows Server 2012 with ReFS system and run some VMs on it for different jobs. VHD will let me manage storage easily. I will play around and to see if I need to have an extra file server or not. Since my current file server is already 4 years old, I might build a FreeNAS next year if necessary.
