Abstract

See full text

Disclosed are systems, methods, and non-transitory computer-readable storage media for uploading a content item to a content management system in fixed size data blocks. A client device can split a content item into fixed size data blocks and create a unique identifier for each of the fixed size data blocks. The unique identifiers can be and transmitted to the content management system to determine which fixed size data blocks are already stored on the content management system. The client device can create a unique identifier for a fixed size data block by using at least a portion of the fixed size data block as input in a hashing algorithm. The resulting hash output can be the unique identifier. The content management system can search for the unique identifiers in a content item index that lists the unique identifier for each fixed size data block stored on the content management system.
