btrfs Wiki
OBSOLETE CONTENTThis wiki has been archived and the content is no longer updated. Btrfs is a modern copy on write (COW) filesystem for Linux aimed at implementing advanced features while also focusing on fault tolerance, repair and easy administration. Its main features and benefits are: Snapshots which do not make the full copy of files RAID - support for software-based RAID 0, RAID 1, RAID 10, .

Btrfs - Wikipedia
Btrfs（B-tree file system : バター エフエス、またはB木 『ビーツリー』 エフエスと読む[1][2]）はLinux向けのコピーオンライトのファイルシステムで、オラクルによって2007年に発表されGNU General Public License (GPL) の元で公開されている[3]。 Btrfsはサン・マイクロシステムズのZFSファイルシステムの影響を受けて開発され、スナップショットやコピーオンライトの機能を持ち、他のLinuxファイルシステムが現在持っている多くの制約を受けないことが期待されているが、開発を主導したオラクルにとっては、2010年のサン・マイクロシステムズ吸収合併により、ZFSと社内で競合する技術になってしまっている。 ext3とext4ファイルシステムの開発者セオドア・ツォー (Theodore Ts'o) は、Btrfsには「reiser3

Incremental Backup - btrfs Wiki
OBSOLETE CONTENTThis wiki has been archived and the content is no longer updated. BTRFS has some key capabilities which enable efficient backup solutions: Instant, Atomic COW Snapshots Since the snapshots are atomic, when a snapshot is restored it appears to applications as if a power loss had occurred (and the filesystem has gone back to an earlier state). Thus it is possible to backup databases

EXT4 vs XFS vs Btrfs vs ZFSをfioでベンチマークを取ってみました。 - Qiita
#概要 CentOS7のデフォルトのファイルシステムがXFSとなりました。 mkfsコマンドでも、minix, xfs, btrfsが使えるようになりました。 そこで気になるファイルシステムを色々調べ、ベンチマークを自分なり取ってみました。 多少なりともご参考になればと思います。 #色々なファイルシステム こちらをご参考ください。 http://qiita.com/sion_cojp/items/c8e015db39ddbf43012e #それぞれファイルシステムを作ってみる 今回の環境は CentOS6（ホスト） 4Core, MEM:32G, HDD:300G CentOS7（ゲスト。こちらで計測しております。） vCPU *1, MEM:4G, HDD:40G 容量が少なかったため、btrfsのベンチマークが終わった後、zfsにファイルシステムを変更し検証をしております。 ### z
