ReFS: Log-Structured

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.

It won’t work out as a common file system for everyday tasks. Check out this overview and see what LSFS is all about.
