Abstract
A method of restoring a storage device includes creating an image of the storage device of a computer system; during execution of a boot loader, starting an initialization application that at least partially restores to the storage device, operating system data from the image; modifying a disk driver of the operating system to form a driver that redirects unexecutable storage device read requests to the image; rebooting the computer system using the at least partially restored operating system data; and restoring unaltered portions of remaining data from the image as a background process.
Claims22
A method of restoring a storage device, the method comprising:
- creating an image of the storage device of a computer system;
- during execution of a boot loader, starting an initialization application that at least partially restores, to the storage device, operating system data from the image;
- modifying a disk driver of the operating system to redirect unexecutable storage device read requests to the image;
- rebooting the computer system using the at least partially restored operating system data;
- and
- restoring unaltered portions of remaining data from the image as a background process.
A method of restoring a storage device of a computing system, the method comprising:
- creating an image of the storage device;
- during execution of a boot loader, starting an initialization application that at least partially restores to the storage device, operating system data from the image;
- modifying a disk driver of the operating system to redirect unexecutable storage device read requests to the image;
- copying portions of data needed for operation of the computing system operation from the image to the computing system on an on-demand basis,
- restoring parts of the storage device corresponding to the data from the image;
- and
- restoring remaining data of the storage device from the image as a background process.
A computer program product for rapid restoration of a server, the computer program product comprising a computer useable medium having computer program logic recorded thereon for controlling at least one processor, the computer program logic comprising:
- computer program code means for creating an image of the storage device of a computer system;
- computer program code means for, during execution of a boot loader, starting an initialization application that at least partially restores to the storage device, operating system data from the image;
- computer program code means for modifying a disk driver of the operating system to redirect unexecutable storage device read requests to the image;
- computer program code means for rebooting the computer system using the at least partially restored operating system data;
- and
- computer program code means for restoring unaltered portions of remaining data from the image as a background process.
A method of restoring a storage device, the method comprising:
- creating an image of the storage device of a computer system;
- during execution of a boot loader, starting an initialization application that at least partially restores, to the storage device, operating system data from the image;
- adding, to a disk driver of the operating system, a disk level filter that intercepts unexecutable storage device read requests and redirects them to the image;
- rebooting the computer system using the at least partially restored operating system data;
- and
- restoring unaltered portions of remaining data from the image as a background process.
A system for restoring a storage device comprising:
- an image of the storage device of a computer system;
- an initialization application that, during execution of a boot loader, at least partially restores, to the storage device, operating system data from the image;
- and
- a disk level filter that intercepts unexecutable storage device read requests of a disk driver of the operating system that are directed to the storage device and redirects them to the image,
- wherein the computer system is rebooted using the at least partially restored operating system data, and
- wherein unaltered portions of remaining data from the image are restored as a background process.
