"BTRFS, then, is much more aggressive than ext4 with
regard to data storage. It has been designed to subsume some of the
features that are normally done by logical volume managers (LVM)
and RAID hardware, does checksums for both its internal metadata
and user data, and has built-in support for snapshots (like an
LVM). Several of these features can be done with ext4, but require
interacting with both the file system and the logical volume
manager.
"Interestingly, BTRFS was initially developed by Oracle (NASDAQ:
ORCL) — which is acquiring Sun — but is now licensed
under the GPL and is thoroughly in the open source community, open
for contribution from anyone. It is described on its own project
pages as "a new copy on write file system for Linux aimed at
implementing advanced features while focusing on fault tolerance,
repair and easy administration.""
