Techniques for managing the storing of a digital asset by a first computer in a computer system that further comprises a second computer. The first computer receives a communication from the second computer including the digital asset, determines whether the digital asset has been stored by the first computer, and when it has not, stores a copy of the digital asset. The digital asset is identified by a first identifier based, at least in part, on its content. In one embodiment, the first identifier is the only identifier that can be used to identify the digital asset in communication between the first and second computers. In another embodiment, the computer system further stores a unit of data comprising the first identifier and metadata relating to the digital asset.

The invention claimed is: 1. A method of managing the storing of a digital asset by a first computer in a computer system that comprises a second computer, the method comprising acts, performed by the first computer, of: (A) receiving, at the first computer, a communication from the second computer
The invention claimed is: 1. A method of managing the storing of a digital asset by a first computer in a computer system that comprises a second computer, the method comprising acts, performed by the first computer, of: (A) receiving, at the first computer, a communication from the second computer including the digital asset, wherein the digital asset is identified in the computer system via a content identifier that is based, at least in part, on the content of the digital asset, wherein the content identifier is the only identifier that can be used to identify the digital asset in any communication between the first and second computers; (B) determining whether the digital asset has been stored by the first computer; and (C) when it is determined that the digital asset is not stored by the first computer, storing a copy of the digital asset. 2. The method of claim 1, further comprising an act, performed by the first computer, of: (D) when it is determined that the digital asset has been stored by the first computer, refraining from having the first computer store a duplicate of the digital asset in response to the receipt of the communication in the act (A). 3. The method of claim 1, wherein the first computer is coupled to the second computer by a network, and wherein the act (A) comprises an act of monitoring the network for a communication including the digital asset. 4. The method of claim 1, wherein the first computer provides content addressable storage. 5. The method of claim 4, wherein the communication comprises the content identifier, and wherein the act (B) comprises an act of comparing the content identifier with a set of asset identifiers that identify a set of digital assets stored by the first computer. 6. The method of claim 1, wherein the first computer is a silo. 7. The method of claim 1, wherein the first computer is coupled to the second computer, and wherein the act (A) comprises an act of receiving the communication from the second computer. 8. The method of claim 1, wherein the first computer is a file server. 9. The method of claim 1, wherein the first computer is a storage system. 10. The method of claim 1, wherein the computer system comprises a plurality of computers in addition to the first and second computers and wherein the plurality of computers are interconnected by at least one network, and wherein each of the plurality of computers manages storage of one or more digital assets. 11. The method of claim 1, wherein the first and second computers are peer computers coupled by at least one network. 12. The method of claim 1, wherein the act (C) comprises an act of storing the digital asset on the first computer. 13. The method of claim 1, wherein the act (C) comprises an act of storing the digital asset on a storage device managed by the first computer. 14. A first computer that manages storage of a digital asset for use in a computer system, wherein the computer system comprises the first computer and a second computer, the first computer comprising: at least one storage device; and at least one controller, coupled to the at least one storage device, that: receives a communication from the second computer including the digital assets, wherein the digital asset is identified in the computer system via a content identifier that is based, at least in part, on the content of the digital asset, wherein the content identifier is the only identifier that can be used to identify the digital asset in any communication between the first and second computers; determines whether the digital asset has been stored on the at least one storage device; and when it is determined that the digital asset is not stored on the at least one storage device, stores a copy of the digital asset. 15. The first computer of claim 14, wherein the at least one controller, when it is determined that the digital asset has been stored on the at least one storage device, refrains from storing a duplicate of the digital asset in response to the receipt of the communication including the digital asset. 16. The first computer of claim 14, wherein the first computer is adapted to be coupled to the second computer by a network, and wherein the at least one controller is adapted to monitor the network for a communication including the digital asset. 17. The first computer of claim 14, wherein the first computer provides content addressable storage. 18. The first computer of claim 17, wherein the communication comprises the content identifier, and wherein the at least one controller compares the content identifier with a set of asset identifiers that identify a set of digital assets stored on the at least one storage device. 19. The first computer of claim 14, wherein the first computer is a silo. 20. The first computer of claim 14, wherein the first computer is coupled to the second computer, and wherein the at least one controller receives the communication from the second computer. 21. The first computer of claim 14, wherein the first computer is a file server. 22. The first computer of claim 14, wherein the first computer is a storage system. 23. The first computer of claim 14, wherein the computer system comprises a plurality of computers in addition to the first and second computers and wherein the plurality of computers are interconnected by at least one network, and wherein each of the plurality of computers manages storage of one or more digital assets. 24. The first computer of claim 14, wherein the first and second computers are peer computers coupled by at least one network. 25. The first computer of claim 14, wherein the at least one controller stores the digital asset on the at least one storage device. 26. A method of managing the storing of a digital asset by a first computer in a computer system that comprises a second computer, the method comprising acts, performed by the first computer, of: (A) receiving, at the first computer, a communication from the second computer including the digital asset, the digital asset being identified in the computer system by a first identifier generated based, at least in part, on the content of the digital asset, the computer system further storing a unit of data that comprises the first identifier and metadata relating to the digital asset, the unit of data being identified via a second identifier generated based, at least in part, on the content of the unit of data; (B) determining whether the digital asset has been stored by the first computer; and (C) when it is determined that the digital asset is not stored by the first computer, storing a copy of the digital asset. 27. The method of claim 26, wherein the method further comprises an act of: (D) when it is determined that the digital asset has been stored by the first computer, refraining from having the first computer store a duplicate of the digital asset in response to the receipt of the communication in the act (A). 28.
