Method of and system for enhanced data storage
View Patent ↗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.
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; 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 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.
2. The system as claimed in claim 1 wherein the main storage stores a set of incremental images.
3. The system as claimed in claim 1 wherein the removable storage component temporarily stores a new uncompressed base image while the uncompressed current base image is compressed using the new uncompressed base image.
4. The system as claimed in claim 1 wherein the storage appliance contains a backup application for initiating a backup sequence which includes storing a base image on the storage appliance.
5. The system as claimed in claim 1 wherein the storage appliance contains a background application for ensuring all of the compressed base images are based on the uncompressed base image.
6. The system as claimed in claim 1 wherein the computing device contains a backup application for initiating a backup sequence which includes storing a base image on the storage appliance.
7. The system as claimed in claim 1 wherein the computing device is selected from the group consisting of a personal computer, a server, a PDA, a laptop, a gaming console and a mobile phone.
8. An apparatus for providing enhanced data storage, comprising:
a. a main storage component for storing an uncompressed base image; and
b. 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.
9. The apparatus as claimed in claim 8 wherein the main storage stores a set of incremental images.
10. The apparatus as claimed in claim 8 wherein the removable storage component temporarily stores a new uncompressed base image while the uncompressed current base image is compressed using the new uncompressed base image.
11. The apparatus as claimed in claim 8 wherein the storage appliance contains a backup application for initiating a backup sequence which includes storing a base image on the storage appliance.
12. The apparatus as claimed in claim 8 wherein the storage appliance contains a background application for ensuring all of the compressed base images are based on the uncompressed base image.
13. 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 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 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.
14. The network of devices as claimed in claim 13 wherein the main storage stores a set of incremental images.
15. The network of devices as claimed in claim 13 wherein the removable storage component temporarily stores a new uncompressed base image while the uncompressed current base image is compressed using the new uncompressed base image.
16. The network of devices as claimed in claim 13 wherein the storage appliance contains a backup application for initiating a backup sequence which includes storing a base image on the storage appliance.
17. The network of devices as claimed in claim 13 wherein the storage appliance contains a background application for ensuring all of the compressed base images are based on the uncompressed base image.
18. The network of devices as claimed in claim 13 wherein each of the plurality of computing devices contains a backup application for initiating a backup sequence which includes storing a base image on the storage appliance.
19. The network of devices as claimed in claim 13 wherein the plurality of computing devices are selected from the group consisting of personal computers, servers, PDAs, laptops, gaming consoles and mobile phones.
