Hi, I'm looking at using a btrfs with snapshots to implement a generational backup capacity. However, doing it the naïve way would have the side effect that for a file that has been partially modified, after snapshotting the file would be written with *mostly* the same data. How does btrfs' COW algorithm deal with that? If necessary I might want to write some smarter user space utilities for this. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
