Method of and system for enhanced data storage

摘要

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.

主权项

1. A system for providing enhanced data storage, comprising:
a. a computing device; and b. a storage appliance coupled to the computing device, wherein the storage appliance further comprises:
i. a main storage component for storing an uncompressed base image; andii. a removable storage component coupled to the main storage component for temporarily storing base images;wherein the removable storage component temporarily stores a first compressed base image while a second compressed base image is decompressed, wherein the decompressed second base image is re-compressed based on a current base image.
