Windows Server 2012: Does ReFS replace NTFS? When should I use it? -

Having a lot of problems with DFSR between 2008R2 and 2012 windows machines, I was migrating to new Windows 2012 servers and tripped over this new files system type called ReFS which replaces NTFS.

The article link at the end of this post gives an excellent summary of all of its advantages and issues and like most MS new products it doesn't seem quite complete yet - such as lacking data de-duplication and not being able to run it on your system boot drive.

It looks like it is suitable for DFSR as it "Preserves & Enforces ACL's" but needs further testing...Ive found other articles which suggest just using ReFS for Archiving Big Data - but why would Microsoft build a new file system just for archiving ?  ReFS support was included in Windows 8.1 betas but seems to have been pulled for the 8.1 release and is rumored to ship with Windows 9

Note:  to see what features a drive supports run fsutil fsinfo volumeinfo
