Systems and methods for restoring data in a degraded computer system
First Claim
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.

Abstract
Methods and systems for restoring data in a degraded computer system are presented. In an embodiment, a method includes storing user data to a hard disk drive that is local to a user interface device. The method may also include storing a sub-set of the user data to a internal data storage device that is local to the user interface device. Additionally, the method may include copying the sub-set of the user data from the internal data storage device to a remote data storage device in response to a degradation of system performance of the user interface device. In an embodiment, the data may be retrieved from the internal data storage by an external system, even when the user interface device is in a degraded or unresponsive state.

6. An Information Handling System (IHS), comprising:
-
a processor; and a memory coupled to the processor, the memory including program instructions stored thereon that, upon execution by the processor, cause the IHS to; 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 the IHS, wherein the hybrid disk drive includes a magnetic disk portion and a solid-state portion, store user data to the magnetic disk portion, store a sub-set of the user data to the solid-state portion, and back 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, launch 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, copy 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. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A non-transitory computer-readable medium having program instructions stored thereon that, upon execution by an Information Handling System (IHS), cause the IHS to:
-
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 the IHS, wherein the hybrid disk drive includes a magnetic disk portion and a solid-state portion, store user data to the magnetic disk portion, store a sub-set of the user data to the solid-state portion, and back 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, launch 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, copy 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. - View Dependent Claims (14)
