Btrfs (pronounced “butter-eff-ess”) is a new copy-on-write checksummed file system for Linux. Some key btrfs features are writable snapshots, pooling of multiple devices, efficient small file support, and optimization for SSDs. This talk will present btrfs from the point of view of the system administrator and casual user.
Btrfs is part of the mainline Linux kernel (therefore, 100% GPLed) and is currently in beta testing. Chris Mason is the architect and lead developer of btrfs. For more information, see the btrfs wiki.
An article on btrfs will appear soon on:
Valerie Aurora Henson is a file systems programmer and author.
