Method of and system for enhanced data storage
First Claim
1. A method of providing enhanced data storage, comprising:
- a. storing a set of compressed base images and an uncompressed base image on a main storage;
b. writing a new base image to an additional storage;
c. compressing the uncompressed base image based on the new base image; and
d. moving the new base image to the main storage.

Abstract
A method of and system for enhanced storage allows more data to be backed up than would otherwise be possible. Instead of storing uncompressed base images and incremental images, differentials of non-current base images are compressed and stored. Furthermore, incremental images that are older than the current base image are removed. By only saving differential base images that are compressed, aside from the newest base image, and deleting older incremental images, a significant amount of space is saved. A removable drive is used as temporary storage in the process of generating a compressed differential base for previous base images. Additionally, a process ensures that previous base images are differentials of the most recent base image and not each other.

8. A network of devices for providing enhanced data storage, comprising:
-
a. a network; b. a plurality of computing devices for sending data to be backed up; and c. a storage appliance coupled to the plurality of computing devices through the network, wherein the storage appliance backs up the data from the plurality of computing devices and further comprises; i. a main storage component for storing a set of compressed base images and an uncompressed base image; and ii. a removable storage component coupled to the main storage component for temporarily storing base images; wherein the removable storage component temporarily stores a new uncompressed base image, while the uncompressed base image is compressed using the new uncompressed base image, then the new uncompressed base image is stored on the main storage component and deleted from the removable storage component. - View Dependent Claims (9, 10, 11, 12, 13)
