RESTORATION OF A BACKUP OF A FIRST VOLUME TO A SECOND VOLUME ON PHYSICAL MEDIA
First Claim
1. A method for restoration of a backup of a first volume to a second volume on physical media, the method comprising:
- accessing a volume boot record of the second volume while the volume boot record is in a valid state on the physical media, the valid state enabling a standard operating system to access a data segment of the second volume;
modifying the volume boot record to place the volume boot record into an invalid state on the physical media, the invalid state preventing the standard operating system from accessing at least a portion of the data segment of the second volume;
while the volume boot record is in the invalid state, writing data from the backup of the first volume to the inaccessible portion of the data segment of the second volume; and
restoring the volume boot record to the valid state.

Abstract
Restoration of a backup of a first volume to a second volume on physical media. In one example embodiment, a method for restoration of a backup of a first volume to a second volume on physical media includes accessing a volume boot record of the second volume while the volume boot record is in a valid state on the physical media, modifying the volume boot record to place the volume boot record into an invalid state on the physical media, writing data from the backup of the first volume to the inaccessible portion of the data segment of the second volume while the volume boot record is in the invalid state, and restoring the volume boot record to the valid state. In this example embodiment, the invalid state prevents a standard operating system from accessing at least a portion of the data segment of the second volume.

7. A method for restoration of an image backup of a first volume to a second volume on physical media, the method comprising:
-
accessing a volume boot record of the second volume while the volume boot record is in a valid state on the physical media, the second volume being divided between a file system metadata segment and a data segment that is separate from the file system metadata segment, the file system metadata segment configured to store blocks of file system metadata, the data segment configured to store blocks of file content, the valid state enabling a standard operating system to access the data segment of the second volume; modifying the volume boot record to place the volume boot record into an invalid state on the physical media, the invalid state preventing the standard operating system from accessing at least a portion of the data segment of the second volume; while the volume boot record is in the invalid state, writing blocks from the image backup of the first volume to the inaccessible portion of the data segment of the second volume; and restoring the volume boot record to the valid state. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for restoration of an image backup of a first volume to a second volume on physical media, the method comprising:
-
creating a base image backup of the first volume; accessing a volume boot record of the second volume while the volume boot record is in a valid state on the physical media, the second volume being divided between a file system metadata segment and a data segment that is separate from the file system metadata segment, the file system metadata segment configured to store blocks of file system metadata, the data segment configured to store blocks of file content, the valid state enabling a standard operating system to access the data segment of the second volume; after the creating the base image backup, modifying the volume boot record to place the volume boot record into an invalid state on the physical media, the invalid state preventing the standard operating system from accessing at least a portion of the data segment of the second volume; while the volume boot record is in the invalid state, writing blocks from the base image backup of the first volume to the inaccessible portion of the data segment of the second volume; while the volume boot record is in the invalid state, creating an incremental image backup of the first volume; while the volume boot record is in the invalid state, writing blocks from the incremental image backup of the first volume to the inaccessible portion of the data segment of the second volume; and restoring the volume boot record to the valid state. - View Dependent Claims (15, 16, 17, 18, 19, 20)
