It was implemented in v3.2, debuting in Windows Server v1709. Data deduplication was missing in early versions of ReFS. Dynamic disks with mirrored or striped volumes are replaced with mirrored or striped storage pools provided by Storage Spaces however, automated error-correction is only supported on mirrored spaces. These include object IDs, 8.3 filename, NTFS compression, Encrypting File System (EFS), transactional NTFS, extended attributes, and disk quotas. Some NTFS features are not implemented in ReFS. Microsoft Windows and Windows Server include ReFSUtil, a command-line utility that can be used to diagnose heavily damaged ReFS volumes, identify remaining files, and copy those files to another volume. ReFS resiliency features enhance the mirroring feature provided by Storage Spaces and can detect whether any mirrored copies of files become corrupt using a data scrubbing process, which periodically reads all mirror copies and verifies their checksums, then replaces bad copies with good ones. ReFS seamlessly integrates with Storage Spaces, a storage virtualization layer that allows data mirroring and striping, as well as sharing storage pools between machines. ReFS supports many existing Windows and NTFS features such as BitLocker encryption, Access Control Lists, USN Journal, change notifications, symbolic links, junction points, mount points, reparse points, volume snapshots, file IDs, and oplock. ReFS supports only a subset of NTFS features – and only Win32 APIs that are "widely adopted" – but does not require new system APIs, and most file system filters continue to work with ReFS volumes. As a result of built-in resiliency, administrators do not need to periodically run error-checking tools such as CHKDSK when using ReFS.Ĭompatibility with existing APIs and technologies

If file data or metadata become corrupt, the file can be deleted without taking the whole volume offline for maintenance, and then be restored from the backup.

The file data can have an optional checksum in a separate "integrity stream", in which case the file update strategy also implements allocation-on-write for file data this is controlled by a new "integrity" attribute applicable to both files and directories. All ReFS metadata have 64-bit checksums which are stored independently. ReFS employs an allocation-on-write update strategy for metadata, which allocates new chunks for every update transaction and uses large IO batches. The file size, number of files in a folder, total volume size and number of folders in a volume are limited by 64-bit numbers as a result, ReFS supports a maximum file size of 16 exbibytes (2 64−1 bytes), and a maximum volume size of 35 petabytes.
Metadata and file data are organized into tables similar to a relational database. ReFS uses B+ trees for all on-disk structures, including all metadata and file data. The key design advantages of ReFS include automatic integrity checking and data scrubbing, elimination of the need for running chkdsk, protection against data degradation, built-in handling of hard disk drive failure and redundancy, integration of RAID functionality, a switch to copy/allocate on write for data and metadata updates, handling of very long paths and filenames, and storage virtualization and pooling, including almost arbitrarily sized logical volumes (unrelated to the physical sizes of the used drives).Ĭomparison with NTFS Major new features Improved reliability for on-disk structures As a result, the file system needs to be self-repairing (to prevent disk checking from being impractically slow or disruptive), along with abstraction or virtualization between physical disks and logical volumes.
These requirements arose from two major changes in storage systems and usage – the size of storage in use ( large or massive arrays of multi-terabyte drives now being fairly common), and the need for continual reliability. ReFS was designed to overcome problems that had become significant over the years since NTFS was conceived, which are related to how data storage requirements had changed. Resilient File System ( ReFS), codenamed "Protogon", is a Microsoft proprietary file system introduced with Windows Server 2012 with the intent of becoming the "next generation" file system after NTFS. com /en-US /windows-server /storage /refs /refs-overview
