Abstract

A distributed image acquisition, storage, and backup system includes a digital camera and a plurality of functionally identical independent storage devices storing digital images. Each digital image is stored as a working copy and a corresponding backup copy on a storage device different from the storage device storing the working copy. One or more storage devices store both a working copy of a first digital image and a backup copy of a second digital image different from the first digital image. Each storage device automatically sends a working copy or backup copy to another of the plurality of storage devices, automatically receives a working copy or backup copy from another of the plurality of storage devices, and automatically stores a received working copy or backup copy.

wherein each storage device of the plurality of storage devices is on a common network and is configured to store information about working or backup copies stored on other storage devices on the common network.

2. The system of claim 1, wherein one or more of the plurality of storage devices form a single, logical storage repository.

3. The system of claim 1, wherein the plurality of storage devices comprises an odd number of storage devices.

4. The system of claim 1, further comprising a network connected to the plurality of storage devices, and a mechanism configured to provide independent access to each of the plurality of storage devices through the network.

5. The system of claim 1, wherein the image capture device is further configured to request and receive a working copy from the plurality of storage devices, and wherein at least one of the plurality of storage devices is configured to:

determine an absence of the requested working copy in a storage device of the plurality of storage devices,

request the requested working copy from another storage device of the plurality of storage devices,

receive the requested working copy from the another storage device, and

transmit the requested working copy to the image capture device.

6. The system of claim 1, wherein at least one storage device of the plurality of storage devices is configured to store a unique combination of working and backup copies.

7. The system of claim 1, wherein the first storage device is configured to store the working copy in a different format from the corresponding backup copy.

8. The system of claim 7, wherein the working copy is accessible faster than the corresponding backup copy.

9. The system of claim 1, further comprising a mechanism configured to reconstitute and store, on one or more of the plurality of storage devices, stored contents of a damaged storage device.

10. The system of claim 1, wherein the common network comprises a common local network.

11. The system of claim 1, wherein the common network comprises a common local network, and wherein each storage device of the plurality of storage devices does not include information about all other storage devices on the common local network or does not include information about all other working or backup copies stored on the other storage devices on the common local network.

12. The system of claim 1, wherein the storage devices of the plurality of storage devices are grouped into two or more storage groups, and wherein the storage devices in each storage group form a single, logical storage repository separate from a single logical storage repository of any other storage group.

13. The system of claim 12, wherein at least one storage device of the plurality of storage devices is a member of two or more storage groups.

14. The system of claim 1, wherein a storage device of the plurality of storage devices is configured to transfer a working copy or backup copy from itself to another storage device, and wherein the other storage device is configured to receive and store the transferred working copy or backup copy.

15. The system of claim 1, wherein a storage device of the plurality of storage devices is configured to make a working copy from a backup copy on itself;

and to transfer the made working copy to another storage device that is configured to receive and store the made working copy.

16. The system of claim 1, wherein a storage device of the plurality of storage devices is configured to make a backup copy from a working copy on itself;

and to transfer the made backup copy to another storage device that is configured to receive and store the made backup copy.

17. The system of claim 1, wherein a backup copy is made in a storage device of the plurality of storage devices in which the backup copy is stored.

18. The system of claim 1, wherein the image capture device is configured to physically connect to a storage device of the plurality of storage devices to transmit digital images from the image capture device to the storage device.

21. The system of claim 4, wherein the independent access is provided based on a security policy that comprises a storage identifier related to the image capture device.

22. The system of claim 5, wherein the absence of the requested working copy is determined using the list.

23. The system of claim 1, wherein each of the plurality of storage devices are configured to store the list.

24. The system of claim 1, wherein at least one of the plurality of storage devices is configured to maintain the list, wherein maintaining the list comprises updating the list based on a presence or absence of the plurality of storage devices and a presence or absence of contents of the plurality of storage devices.

25. The system of claim 1, wherein the image capture device or one of the plurality of storage devices comprises a requesting mechanism configured to request a working copy from another storage device of the plurality of storage devices, and wherein the other storage device comprises a retrieval and transmission mechanism configured to retrieve and transmit the requested working copy to the image capture device or to the one of the plurality of storage devices.

26. The system of claim 7, wherein the corresponding backup copy is more compressed than the working copy.

19. A system comprising:

a plurality of storage devices, wherein each storage device of the plurality of storage devices is configured to receive and to store digital images from an image capture device, wherein each of the digital images is stored as a working copy on a first storage device of the plurality of storage devices and is stored as a corresponding backup copy on a second storage device of the plurality of storage devices different from the first storage device, wherein the first storage device is further configured to store both a first working copy of a first digital image and a first backup copy of a second digital image different from the first digital image, wherein at least one of the plurality of storage devices is configured to store a list, and wherein the list contains information relating to the plurality of storage devices and contents of the plurality of storage devices;
