Abstract

Each of plural multimedia files desired to be backed up are transformed into vector representations and divided into segments, and the segments are sent to respective participating computers in a network as a means of backing up the files. The multimedia files can be recovered and may be reconstituted with less than 100% of the segments with minimal deleterious noticeability upon subsequent display of the content in the files.

Claims

1. A computer comprising:

one or more processors operable to;

select, at predefined intervals, a multimedia file to be backed up bases on a plurality of predefined rules;

transform the selected multimedia file into vectors;

divide the transformed multimedia file into a plurality of segments;

tag each of the plurality of segments with an identification indicating the multimedia file to which each of the plurality of segments belongs; and

send each of the plurality of segments to a respective participating backup computer in a computer network such that the plurality of segments of the multimedia file are distributed among a plurality of participating computers,

wherein a first input is received from a user to establish an acceptable file percentage for recovery of the multimedia file,

wherein a second input is received from the user to receive a threshold period of time for the recovery of the multimedia file, and

wherein, in an event a percentage corresponding to a number of the plurality of segments recovered within the threshold period of time is equal or more than the acceptable file percentage, the multimedia file is indicated as being fully recovered, the acceptable file percentage being less than 100%.

2. The computer of claim 1, wherein each of the plurality segments is tagged with an indication of a location of the segment within the multimedia file.

3. The computer of claim 1, wherein the one or more processors are operable to transform the multimedia file into vectors, the plurality of segments being composed of the vectors.

4. The computer of claim 3, wherein the multimedia file is transformed into the vectors prior to dividing the multimedia file into the plurality of segments.

5. The computer of claim 1, wherein the one or more processors are operable to record which participating backup computer receives which segment of the plurality of segments to generate a location record.

6. The computer of claim 5, wherein the location record is provided to a network server for access in an event that the location record cannot be accessed in the computer.

7. The computer of claim 1, wherein in an event the percentage of the received number of plurality of segments corresponding to the multimedia file for recovery is less than the first input received for the established acceptable file percentage, a third input is received from the user to receive another acceptable file percentage,

wherein the another acceptable file percentage is less than the first input of the acceptable file percentage, and

wherein, in an event the percentage of the number of plurality of segments recovered within the threshold period of time is equal or more than the another acceptable file percentage, the multimedia file is indicated as being fully recovered.

8. A computer comprising:

one or more processors operable to;

automatically select, at predefined intervals, a multimedia file to be backed up based on a plurality of predefined rules;

receive a recovery command to recover the multimedia file after being backed up, the multimedia file having a plurality of segments stored on a plurality of participating computers,

wherein the recovery command includes information corresponding to;

an acceptable file percentage for recovery of the multimedia file as a first input, and

a threshold period of time for the recovery of the multimedia file as a second input;

communicate with the plurality of participating computers to download the plurality of segments; and

combine the plurality of segments using identification tags associated with each of the plurality of segments to reconstruct the multimedia file to the acceptable file percentage of an original version of the multimedia file, the acceptable file percentage being less than 100%, wherein, in an event a percentage corresponding to a number of the plurality of segments recovered within the threshold period of time is equal or more than the acceptable file percentage, the multimedia file is indicated as being fully recovered.

9. The computer of claim 8, wherein the plurality of segments are backed up as the vectors and the one or more processors are operable to transform the vectors to the original version of the multimedia file.

10. The computer of claim 8, wherein the one or more processors are operable to present thumbnail images on a display of the computer, each thumbnail image representing a respective multimedia file, and generate a command to recover the multimedia file associated with the thumbnail selected by a user.

11. The computer of claim 8, wherein the one or more processors are operable to receive a third input from a user corresponding to a path name to designate the multimedia file for recovery.

12. The computer of claim 8, wherein the one or more processors are operable to:

tag each of the plurality of segments with the identification tags indicating the multimedia file to which each of the plurality of segments belongs; and

send each of the plurality of segments to a respective participating backup computer in a computer network such that the plurality of segments of the multimedia file are distributed among multiple backup computers.

13. The computer of claim 8, wherein each of the plurality of segments is tagged with an indication of a location of the segment within the multimedia file.

14. The computer of claim 8, wherein the one or more processor are operable to transform the multimedia file into vectors, the plurality of segments being composed of the vectors.

15. The computer of claim 14, wherein the multimedia file is transformed into the vectors prior to dividing the multimedia file into the plurality of segments.

16. The computer of claim 8, wherein the one or more processors are operable to record which participating computer receives which segment of the plurality of segments to generate a location record.

17. The computer of claim 16, wherein the location record is provided to a network server for access in an event that the location record cannot be accessed in the computer.

18. The computer of claim 8, wherein the multimedia file comprises at least one of video file, digital image file and audio file.

19. A method comprising:

automatically designating, at predefined intervals, a multimedia file to be backed up based on a plurality of predefined rules;

transforming the multimedia file into vectors;

dividing the transformed multimedia file into a plurality of segments;

sending the plurality of segments to respective participating computers in a network for backing up the multimedia file;

recovering the multimedia file by downloading the plurality of segments from the participating computers,

wherein a first input is received from a user to establish an acceptable file percentage for recovery of the multimedia file,

wherein a second input is received from the user to receive a threshold period of time for the recovery of the multimedia file, and

wherein, in an event a percentage corresponding to a number of plurality of segments recovered within the threshold period of time is equal or more than the acceptable file percentage, the multimedia file is indicated as being fully recovered; and

reconstituting the multimedia file with less than 100% of the plurality of segments.

20. The method of claim 19, further comprising transforming the multimedia file into vector representations.
