Resilient File System (ReFS) was introduced with Windows 2012 with the goal of enhancing some of the existing features on the NTFS file system, as the name implies ReFS main goal is having a resilient file system able to guarantee data security and resiliency in case of disaster.
Some of the key features and goals of ReFS are:
- Maintain compatibility with some of the features part of the NTFS file system while at the same time deprecating all those features delivering limited value at the cost of complexity and footprint
- Verify and auto-correct data. We all know data can and will get corrupted ReFS aim to very and whenever possible correct data automatically
- Never take the file system offline even in the event of corruption ReFS will isolate the fault while still allowing access to the rest of the volume, data recovery will happen behind the scenes all “live”
- Metadata integrity with checksums
- Allocate on write transactional model for robust disk updates (also known as copy on write)
The list is rather long and could go on but the main focus of the article is showing you how to configure a new volume with ReFS
ReFS Create a new volume
To create a ReFS volume in Server Manager open [File and Storage Services] → [Volumes] → [Disks] right-click the disk that will be formatted with ReFS file system and select New Volume
Once the ReFS volume has been created you can start using the disk volume right away taking full advantage of new and enhanced features for example to store Exchange databases.
