Abstract: An information handling system includes a storage and a processor. The storage stores a key file in a partition of the storage. The processor receives a request for the key file and determines whether the key file is located within the partition of the storage.

The processor determines a physical location for the key file based on the metadata. Based on the physical location, the processor retrieves segments of the key file from the partition of the storage. The processor downloads segments of the key file from a backend server. The processor re-creates the key file based on the segments of the key file retrieved from the partition of the storage and on the segments of the key file downloaded from the backend server.
