Definition - What does Resilient File System (ReFS) mean?
Resilient File System (ReFS) is a type of disk file system that provides a disk storage management platform to Windows 8 server operating systems. Introduced in the Windows 8 server edition, ReFS is built on its predecessor, New Technology File System (NTFS), but with enhanced capabilities. Integrated with Storage Spaces, it is designed to repair disk corruption in an automated fashion.
ReFS is also known as Protogon.
The design objective of ReFS for Windows 8 Server is to guarantee data integrity via resiliency to corruption, regardless of software or hardware failures.
The following are key ReFS features:
Increased resiliency against data and disk corruption
Reliable on-disk structures and file integrity streams
Prevention of disk rotting via disk scrubbing ReFS also incorporates popular features from the NTFS codebase, including symbolic links, reparse points, BitLocker, security mechanisms and volume snapshots. Certain NTFS features (named stream, quotas, object IDs, compression) are not included in ReFS.
