Microsoft has revealed details about ReFS (Resilient File System), a new file system that will be introduced with Windows Server 8. You can learn about it at ZD Net.
ReFS will begin life as a storage system for Windows Server only. Then — some time post Windows 8 — it will become a storage system for Windows clients, and then ultimately “as a boot volume,” said author of the post, Surendra Verma, a development manager on the Windows Storage and File System team. (Interestingly, when the first leaks about ReFS, codenamed Protogon, occurred last year, those who discovered the new file system found it in leaked Windows 8 client builds.)
NTFS, the New Technology File System, has been part of Windows since Windows XP and Windows NT 3.1 were introduced in 2001 and 1993, respectively. (Thanks for the date corrections, readers.)
There are some NTFS features for which Microsoft plans to drop support with ReFS, specifically named streams, object IDs, short names, compression, file level encryption (EFS), user data transactions, sparse, hard-links, extended attributes, and quotas, Verma blogged. That said, one of Microsoft’s goals with ReFS is to “maintain a high degree of compatibility with a subset of NTFS features that are widely adopted while deprecating others that provide limited value at the cost of system complexity and footprint,” Verma said.
