There was an error updating the deduplication volume

Other enhancements cover the redo log (for synchronous disk writes), parallelization, efficient tracking of uninitialized sparse data and files, and efficient 4k I/O.

Other operating systems have competing file systems to Re FS, of which the best known are ZFS and Btrfs, in the sense that all three are designed to integrate data protection, snapshots, and silent high speed background healing of corruption and data errors.

In 2012, Phoronix wrote an analysis of Re FS vs Btrfs, a copy-on-write file system for Linux.

Their features are similar, with both supporting checksums, RAID-like use of multiple disks, and error detection/correction.

The file data can have an optional checksum in a separate "integrity stream", in which case the file update strategy also implements allocation-on-write for file data; this is controlled by a new "integrity" attribute applicable to both files and directories.

As a result, the file system needs to be self-repairing (to prevent disk checking from being impractically slow or disruptive), along with abstraction or virtualization between physical disks and logical volumes.Its primary use case is on file servers that store extremely large amounts of data.It has data integrity and recovery mechanisms built into the file system, as well.That means those tools that are designed to detect and repair file corruption in other file systems aren’t necessary, so their incompatibility with Re FS isn’t really an issue.Additionally, although Re FS doesn’t support file level (Encrypting File System) encryption, Bit Locker can be used to protect Re FS volumes so that’s not so much of an issue, either [...] Re FS has some distinct advantages over current reigning Windows file system NTFS, but it also has some drawbacks.
