Can anyone clarify that? I think the purpose is that on meta data corruption (which can happen and is probably more important than file data) the file system can "heal" itself by replacing a corrupted meta data block with an intact copy. Also during scrubbing btrfs will check all those blocks and magically fix broken ones.
