Abstract:
A method for updating a plurality of disk images, each of the plurality of disk images derived from a common base disk image and a delta image comprising a plurality of delta files, includes applying a delta file to a base disk image to generate a second disk image comprising a portion of the base disk image modified by the delta file and an unmodified portion of the base disk image. Each delta file represents at least one difference between one of the plurality of user disk images and the base disk image. The method includes applying a patch to a copy of the base disk image, and determining that the patch is applied to a portion of the base disk image corresponding to the unmodified portion of the base disk image. The delta file is applied to the patched copy of the base disk image.
