InternetNews talks to developers and vendors about the rise of Btrfs as a successor to Ext4. Though Ext4 adds extents, Chris Mason, Btrfs developer noted that BTRFS adds a number of other features beyond that. Among those features are items like snapshotting, online file consistency checks and the ability to perform fast incremental backups. BTRFS (pronounced better FS) is currently under development in an effort led by Oracle engineer Chris Mason. With the support of Intel, Red Hat, HP, IBM, BTRFS could become the engine that brings next generation filesystem capabilities to Linux.

Even when it reaches v1.0, BTRFS will be far behind ZFS.
Just look at the features.
Also there are no current plans for transparent compression on BTRFS, and I consider that a must for many cases.
Not to mention the ZFS syntax is so dead plain simple.
Not so for BTRFS.
I run ZFS on Linux (for a long time now!) via FUSE, and I'm very happy with it

Sure it won't implement all the "advanced" features, but it will implement all the features people cares about - mutiple device management, raid-z, selfhealing, cheap snapshots. And other features (like I/O priority) don't even need to be implemented by btrfs because they are already implemented in the generic block layer.

Transparent compression on btrfs was merged two days ago - http://git.kernel.org/?p=linux/kernel/git/mason/btrfs-unstable-stan...

You are behind the times.

once it hits 1.0 this file system will make you breakfast if you want it to. its going to be amazing. with huge colaboration by vendors and distrobutions like RedHat, this is going to be the future of Linux FS. I for one welcome it, its about time ZFS had some competition (though they have a ways to go)
