Oracle's TechCast crew
interviewed [.mp3] Chris Mason on
Btrfs. A kind-of transcript is available
here. Btrfs is a new filesystem for Linux developed by Oracle. It features:
"extent based file storage (264 max file size); space efficient packing of small files; space efficient indexed directories; dynamic inode allocation; writable snapshots; subvolumes (separate internal filesystem roots); object level mirroring and striping; checksums on data and metadata (multiple algorithms available); strong integration with device mapper for multiple device support; online filesystem check; very fast offline filesystem check; efficient incremental backup and FS mirroring."
