ReFS (Resilient File System – https://msdn.microsoft.com/en-us/library/windows/desktop/hh848060%28v=vs.85%29.aspx) is a Microsoft file system, which ensures data integrity by means of resiliency to corruption (irrespective of software or hardware failures), increases data availability and scales to large data sets across various workloads. Its data protection feature is represented with the FileIntegrity option, which is responsible for file scanning and repair processes.

ReFS: Log-Structured

4.5/5 (2)

Here is a part of a series about Microsoft Resilient File System, first introduced in Windows Server 2012. It shows an experiment, conducted by StarWind engineers, dedicated to seeing the ReFS in action. This part is mostly about the FileIntegrity feature in the file system, its theoretical application and practical performance under real virtualization workload. The feature is responsible for data protection in ReFS, basically the reason for “resilient” in its name. It’s goal is avoidance of the common errors that typically lead to data loss. Theoretically, ReFS can detect and correct any data corruption without disturbing the user or disrupting production process.

Log-Structured File Systems: Overview

Log-Structured File System is obviously effective, but not for everyone. As the “benefits vs. drawbacks” list shows, Log-Structuring is oriented on virtualization workload with lots of random writes, where it performs like a marvel. It won’t work out as a common file system for everyday tasks. Check out this overview and see what LSFS is all about.
