1. A method, comprising:

  • while in a normal state under control of a primary operating system stored in a magnetic disk portion of a hybrid disk drive that is local to a user interface device, wherein the hybrid disk drive includes a magnetic disk portion and a solid-state portion, storing user data to the magnetic disk portion, storing a sub-set of the user data to the solid-state portion, and backing up the user data from the magnetic disk portion to a remote storage device, wherein the user data, the sub-set of the user data, and the backed-up user data are each current;

    while in a degraded state, launching an alternate operating system stored in the solid-state portion, wherein the user data is lost, the sub-set of the user data is current, and the backed-up user data is stale; and

    while in a restoring state under control of the alternate operating system, copying the sub-set of the user data from the solid-state portion to the remote storage device, wherein the sub-set of the user data is usable by the remote storage device to make the backed-up user data current.
