→ A short history of btrfs
aug 01 2009
Very interesting overview of the btrfs design, its history and its relationship to ZFS.
I really want ZFS or btrfs to become widespread and stable enough that I can use them on my Mac and Linux machines. It’s unfortunate that Mac OS X will probably go ZFS and Linux will go btrfs, which hurts interoperability.
It’s not clear to me if btrfs has as strong a focus on data integrity as ZFS. I was thoroughly impressed when Jeff Bonwick (the founder and designer of ZFS) came to UIUC and did a data integrity demo. In the demo he created a filesystem and then scribbled randomly over a large percentage of the disk, and showed how ZFS was on the fly repairing the damage.
