A cloud storage system supporting user agnostic encryption and deduplication of encrypted files is described. Further the cloud storage system enables users to share a file, a group of files, or an entire file system with other users without a user sending each file to the other users. The cloud storage system further allows a client device to minimize the utilization of bandwidth by determining whether the encrypted data to transfer is already present in the cloud storage system. Further the cloud storage system comprises mechanisms for a client device to inform the cloud storage system of which data is likely to be required in the future so that the cloud storage system can make that data available with less latency one the client device requests the data.

Cloud file system

Protecting content is disclosed. A request for a file system operation is intercepted. A user-defined callback that corresponds to the file system operation is identified. The user-defined callback that secures the file system operation is executed. The user-defined callback may be used for pre or post-processing of data, authentication, and/or other use cases.

Data protection file system

A request to store a file to be protected is received. It is detected whether the file to be protected is a file to be synchronized. The encryption key is selected based on the detection of whether the file is a file to be synchronized. The file to be protected is encrypted using the selected encryption key.
