    [$] Btrfs: Subvolumes and snapshots
    The previous installment in LWN's ongoing
    series on the Btrfs filesystem covered multiple device handling: various
    ways of setting up a single filesystem on a set of physical devices.
    Another interesting aspect of Btrfs can be thought of as working in the
    opposite manner: subvolumes allow the creation of multiple filesystems on a
    single device (or array of devices). Subvolumes create a number of
    interesting possibilities not supported by other Linux filesystems. This
    article will discuss how to use the subvolume feature and the associated
    snapshot mechanism.
