Btrfs - Next generation file system for linux

Jan 14, 2009, 22:01 (1 Talkback[s])

"There has been quite a lot of filesystem work done in the past few kernel versions. The ext4 file system was added as a development version in late in 2006 (Initial git commit) and was declared stable exactly two years later. (commit to rename ext4dev to ext4) ext4 is a nice evolution of the ext series of file systems and provides a number of new features such as larger storage limits, and extent based storage. See the wikipedia article on ext4 for more detail. But ext4 is still just a file system and doesn't really compete with the newest kid on the block, ZFS.

"ZFS is the feature rich, "rampant layering violating" file system that Sun has developed for it's version of UNIX, Solaris. ZFS has a few key features that make linux users green with envy: quick and easy snapshots of data, data checksumming, and integration of several tools to manage disks and file systems."
