## Abstract

A method for storing objects in an object storage system includes the steps of establishing a network connection with a client over an inter-network, receiving an upload request indicating an object to be uploaded by the client, selecting at least two storage nodes on which the object will be stored, receiving the object from the client via the network connection, and streaming the object to each of the selected storage nodes such that the object is stored on each of the selected storage nodes. The method can also include writing an object record associating the object and the selected storage nodes to a shard of an object database and generating a Universally Unique Identifier (UUID). The UUID indicates the shard and the object ID of the object record, such that the object record can be quickly retrieved. Object storage infrastructures are also disclosed.

### Claim 3 (depends on 2)

The method of claim 2, further comprising:
generating a new object record associated with said digital object; and
modifying said new object record according to an existing object record associated with an existing digital object that is identical to said digital object and was previously stored on at least one of said selected storage nodes.

### Claim 4 (depends on 3)

The method of claim 3, wherein said step of generating a new object record associated with said digital object includes associating said new object record with said existing object record.

### Claim 5 (depends on 2)

The method of claim 2, wherein said step of selecting multiple storage nodes from said set of storage nodes includes selecting at least one storage node hosted on another Internet cloud system other than said object storage system.

### Claim 6 (depends on 1)

The method of claim 1, wherein:
said step of receiving said digital object includes storing said digital object on said selected storage node; and
said step of preventing retention of multiple copies of said digital object on said selected storage node includes, if said digital object was previously stored on said selected storage node, removing said digital object or said previously stored copy of said digital object.

### Claim 7 (depends on 1)

The method of claim 1, wherein:
said step of generating a hash value associated with said digital object includes generating a checksum associated with said digital object; and
