While provisioning a 60-TB mirrored Storage Spaces volume on Windows Server 2022, you select the Resilient File System (ReFS) instead of NTFS. To protect the archive against silent bit-level corruption, you want to enable the ReFS feature that keeps per-file checksums, detects bad data during reads or scheduled scrubbing, and automatically repairs the block by copying a good version from the mirror. Which capability must you turn on?
Integrity streams is the ReFS mechanism that creates and verifies checksums for user data. When a checksum mismatch is detected, ReFS working with a resilient Storage Spaces configuration can pull an intact copy from the mirror and write it back, providing self-healing without administrator intervention. Features such as Encrypting File System (EFS), file-system compression, and Transactional NTFS are either NTFS-only or unrelated to data-integrity repair, so they do not meet the requirement.
