Hi Samuel Fernandes!

ReFS does not itself offer deduplication. One side effect of its familiar, pluggable, file system architecture is that other deduplication products will be able to plug into ReFS the same way they do with NTFS.

ReFS does not explicitly implement a second-level cache, but customers can use third-party solutions for this.

ReFS and VSS work together to provide snapshots in a manner consistent with NTFS in Windows environments. For now, they don't support writable snapshots or snapshots larger than 64TB.
