Abstract
Headstart restore of a first volume to a second volume. In one example embodiment, a method for headstart restore of a first volume to a second volume may include invalidating, on disk, a boot segment of a volume boot record of the second volume, storing headstart restore information in the second volume, while the boot segment of the volume boot record of the second volume remains invalidated, writing data from one or more backups of the first volume to a data segment of the second volume, removing the headstart restore information from the second volume, and revalidating, on disk, the boot segment of the volume boot record of the second volume.

A method for headstart restore of a first volume to a second volume, the method comprising:
- invalidating, on disk, a boot segment of a volume boot record of the second volume;
- storing headstart restore information in the second volume;
- while the boot segment of the volume boot record of the second volume remains invalidated, writing data from one or more backups of the first volume to a data segment of the second volume;
- removing the headstart restore information from the second volume;
- and
- revalidating, on disk, the boot segment of the volume boot record of the second volume.
A method for headstart restore of a first volume to a second volume, the method comprising:
- modifying, on disk, a boot segment of a volume boot record of the second volume in order to make the second volume unmountable and inaccessible to a standard file system;
- storing headstart restore information in the second volume, the headstart restore information including information about where the second volume is in a headstart restore process;
- while the boot segment of the volume boot record of the second volume remains invalidated and while the second volume remains unmounted and inaccessible to a standard file system, writing data from a full image backup of the first volume and from one or more incremental image backups of the first volume to a data segment of the second volume;
- removing the headstart restore information from the second volume;
- and
- revalidating, on disk, the boot segment of the volume boot record of the second volume in order to once again make the second volume mountable and accessible to the standard file system.
