Software updates using delta patching
First Claim
1. A method comprising:
- comparing, by a first computer, a first image representative of a plurality of software stacks, a second image representative of at least one and less than all of the plurality of software stacks to determine a difference between the second image and the first image, and a third image representative of the second image and at least one new software stack, the at least one new software stack being different from any one of the plurality of software stacks;
generating, by the first computer, a file representative of the difference between the third image and the first image, the file including instructions for removing each software stack of the plurality of software stacks represented in the first image and not represented in the second image from a second computer, the file further including instruction for adding the at least one new software stack to the second computer; and
recording to a computer-readable storage medium data representing the file,wherein each software stack of the plurality of software stacks is a different version of an operational software stack.

Abstract
Methods, apparatuses, and systems for software updates using delta patching are described. A first computer may compare a first image representative of a plurality of software stacks, and a second image representative of at least one and less than all of the plurality of software stacks to determine a difference between the second image and the first image. The first computer may generate a file representative of the difference between the second image and the first image. The file may include data of instructions for removing each software stack of the plurality of software stacks represented in the first image and not represented in the second image from a second computer. Data representative of the file representative of the difference between the second image and the first image may be recorded to a computer-readable storage medium.

18. An apparatus comprising:
-
at least one processor; and at least one memory, the at least one memory storing computer-readable instructions that, when executed by the at least one processor, cause the at least one processor to perform a method of; generating a first image representative of plurality of software stacks, a second image representative of at least one and less than all of the plurality of software stacks to determine a difference between the second image and the first image, and a third image representative of the second image and at least one new software stack, the at least one new software stack being different from any one of the plurality of software stacks; comparing, the first image, and the third image to determine a difference between the third image and the first image, wherein each software stack of the plurality of software stacks is a different version of an operational software stack; generating, by the first computer, a file representative of the difference between the third image and the first image, the file including instructions for removing each software stack of the plurality of software stacks represented in the first image and not represented in the second image from a computer, the file further including instruction for adding the at least one new software stack to said computer; and recording to a computer-readable storage medium data representing the file. - View Dependent Claims (19, 20)
