US 2006/0051157 A1 · Systems, methods, and media for backing up a computer system

Abstract

Systems, methods and media for backing up a hard disk drive of a computer system are disclosed. Embodiments include capturing a series of commands to modify data on the hard disk drive, executing a data modification based on the series of commands, and storing an indication of the data modifications to one or more data storage devices. The data storage device may be used to help restore the hard disk drive in the event of loss of data from the primary hard disk drive. In one embodiment, the computer system may be a portable computer system and the data storage device may be a solid state storage device. In another embodiment, a second data storage device may be an external hard drive that mirrors the primary hard drive and is replicated at a remote location.

Dependent claims

A backup system for a computer system having a primary hard disk drive, the system comprising:

a portable data storage device, the portable data storage device being adapted to serve as a cache;
a capture module, the capture module being adapted to capture any commands to modify data on the primary hard disk drive;
a cache writing module in communication with the capture module, the cache writing module being adapted to store indications of any commands to modify the data captured by the capture module to a cache on the portable data storage device;
a mirroring module in communication with the capture module, the mirroring module being adapted to mirror the primary hard disk drive on to the external data storage device;
and
a network backup module, the network backup module being adapted to replicate the mirrored copy of the primary hard disk drive stored on the external data storage device to a remote storage location via a network.
