Which of the following features isn't supported by ReFS?

Data deduplication
Data compression
The ability to remediate integrity issues online
File versioning

The correct answer is: Data compression

The correct answer is that data compression is not supported by ReFS (Resilient File System). ReFS is designed with a focus on data integrity, availability, and resilience against data corruption, particularly in enterprise environments. It achieves this through features such as integrity checks and automatic repair of corrupt data, which is why it supports online remediation of integrity issues. Data deduplication is available for ReFS volumes, providing storage efficiency by eliminating duplicate copies of data. While file versioning isn't a native feature of ReFS itself, it can integrate with Windows features that offer versioning capabilities. However, data compression, which is a long-standing feature in NTFS, is intentionally omitted from ReFS to maintain its performance and integrity advantages. Focusing on data integrity and resilience, ReFS prioritizes these aspects over traditional file system features like compression, which can interfere with the system's ability to provide robust data integrity checks and recover from corruption.
