Linux 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.

Well, it is and it isn't. Silent corruption is generally the result of problems elsewhere, and in the case of Solaris, usually its the pretty arcane and old device drivers. Unless you're prepared to use ZFS to find out what went wrong and to fix it, the frenzied excitement over ZFS detecting 'silent corruption' is pretty laughable.

Well...detecting corruption is always useful. It means there's an issue somewhere, most likely hardware, and if it is indeed a hardware issue it's good to know about it before it gets worse. The ZFS ability to sometimes fix the corruption is good, but I do consider it more useful to have a warning about malfunctions.

On the other hand, if your system finds corruptions, fixes them, and you are just glad it got fixed and continue whatever you did without checking what the issue is...then you are quite ignorant and in a risk of losing a part or all of your data on the disk. Trusting it to get automatically fixed without your intervention is foolish.
