Details on the implementation's internals are not released, which makes it difficult to implement. It was introduced with the NT line of operating systems, superseding FAT as the preferred file system. The New Technology File System (NTFS) is another file system designed by Microsoft.

The integration already allowed to send some bug fixes upstream to WinBtrfs proper.Ĭommit history (Source code can be found in: /reactos/drivers/filesystems/ntfs) As part of the Google Summer of Code 2018, Victor Perevertkin wrote the Btrfs support code for FreeLoader, allowing ReactOS to boot from Btrfs directly. In 2016 Peter Hater and Pierre Schweitzer started the integration into ReactOS.

The driver used is an in-tree copy of Mark Harmstone's fully-featured WinBtrfs driver for Microsoft Windows. This includes support for creating Btrfs filesystems (in the installer at least), installingĪnd running ReactOS (read-write) from Btrfs and a shell extension adding a "Btrfs" tab to the drive properties dialog. Since version 0.4.10 ReactOS can be installed on Btrfs.

Btrfs snapshots - ideal for differential backup solutions.

Online defragmentation (defrag) and checksum check (scrub).

Built-in RAID 0,1,5,6,10 support - a Btrfs filesystem can span multiple disks, the user can select trade-offs (RAID levels) between data redundancy/space economy and performance.

Subvolumes - this feature allows to "partition" a Btrfs filesystem in separate filesystem hierarchies, which can be separately mounted - basis of the snapshot feature.

Data checksumming - all data is checksummed on read and write - this can detect hardware errors previously undetected.

Maximum filesize of more than 16 Exabytes.

B-tree design - in contrast to a table-based system like FAT.

Foundation of the fast and "low-cost" Btrfs snapshots On modification, the original data is left untouched.

Copy-on-Write (COW) - Instead of "deep copying", file copies start as light-weight references.

It was designed to supersede the ext series of Linux filesystems. In the meantime, Microsoft themselves open-sourced their fastfat.sys - attempts to integrate it into ReactOS have shown that our kernel isn't 100% ready yet.Ĭommit history (Source code can be found in: /reactos/drivers/filesystems/btrfs)ītrfs is a Linux filesystem of the "next generation". The driver (fastfat.sys) has gone through several iterations, including an attempt to rewrite it with the FullFAT library. It is also commonly used on flash media and external hard drives, which ReactOS intends to be able to read with pending USB mass storage support.įAT32 is the file system that has been supported by ReactOS for a long time now, ReactOS can read, write and boot from it. This makes FAT32 an effective file system for sharing files between operating systems. The FAT file system is supported across a variety of other operating systems, including GNU/Linux, FreeBSD, BeOS, Mac OS X, and FreeDOS. It is simple and easy to understand compared to other common file systems.
