Finally Microsoft has made a new filesystem! (besides fat filesystem family)
It is called REFS!
However it does look like a clone of ZFS or BTRFS though, but who cares?
It is called REFS!
The key features of ReFS are as follows (note that some of these features are provided in conjunction with Storage Spaces).
Metadata integrity with checksums
Integrity streams providing optional user data integrity
Allocate on write transactional model for robust disk updates (also known as copy on write)
Large volume, file and directory sizes
Storage pooling and virtualization makes file system creation and management easy
Data striping for performance (bandwidth can be managed) and redundancy for fault tolerance
Disk scrubbing for protection against latent disk errors
Resiliency to corruptions with "salvage" for maximum volume availability in all cases
Shared storage pools across machines for additional failure tolerance and load balancing
