With this configuration, if corruption were to be encountered, ReFS can immediately leverage redundant data within Storage Spaces to expediently address the issue. When coupled with a mirrored Storage Space, duplicate copies of data will automatically be leveraged by ReFS. Storage Spaces and ReFS complement each other. When coupled with redundancy through Storage Spaces, it is default behavior for Integrity Streams to be enabled for the entire volume. You may enable Integrity Streams on particular folders, volumes, or even granularly on a per-file basis. When configured to do so, checksums are used against written data and updates are done using copy-on-write. If you want additional protection of data streams, you may enable Integrity Streams. File system metadata is protected against corruption. However, don’t think that because this is so that file system metadata is conventional also. By default, ReFS uses conventional streams which behave identically to NTFS data streams. Further, ReFS may be used with clusters, Hyper-V, file shares, data archival, and many other uses.Īdditional integrity data streams may be enabled if you have additional needs for data protection. ReFS is able to recover from corruption within the file system rapidly without limiting availability of the volume. Once successfully written, the file system can free the space used by the old data stream. In fact, when data is written to disk, it is written to a new location on disk rather than over the top of existing data. ![]() ![]() ReFS can use checksums to detect if data has changed since last written and is able to detect and recover from corruption quickly. And for what it’s worth, Windows Server 2012 contains improvements for CHKDSK. Yep…there’s no need for extra tools to go fix corruption like with other file systems. The truth is that in terms of ReFS partitions, ReFS doesn’t need CHKDSK because repair functionality is built-into the file system. It’s okay to have those feelings if you have them. Are you feeling that the tool you’ve wanted to avoid for so long is now something you might want to hold onto…just in case? A love-hate relationship perhaps? The counselor is in. Yes…I did just indicate that there’s no need to run CHKDSK on a ReFS partition. These are features that a conventional file server or data repository does not require.ĬHKDSK isn’t applicable to ReFS. For example, Windows Deployment Services (WDS) explicitly requires NTFS because it relies on specific features in order to implement the RemoteInstall folder structure used for storing images. However, many may have no issues due to ReFS compatibility with many of the Win32 storage APIs. Applications that run locally on the server and rely on specific NTFS features may not work with ReFS. ReFS is ideal for storing large amounts of data and can be leveraged for file shares. In fact, disk tools that work with the NTFS Master File Table (MFT) won’t be able to work with ReFS because ReFS has its own mechanism for keeping up with file metadata. The Resilient File SystemĪlthough ReFS inherited some of the NTFS code base initially, it is a different file system with different uses in mind. While ReFS may appear to have some similarity to NTFS, it does not contain all the underlying NTFS features and scales efficiently to handle data sets far larger than NTFS. ![]() In learning about this new file system in Windows Server 2012, it became apparent fairly quickly that ReFS, while a new file system, is built differently. It didn’t take long before my customers began to ask me the same question. When I first heard of ReFS my immediate first question was whether ReFS as a file system was a direct replacement for NTFS.
