17. The system of claim 1 , wherein the server-stored data stored on the server storage system comprises client identifier data.

18. The system of claim 1 , wherein the server-stored data stored on the server storage system comprises video data, audio data, accelerometer data, global positioning system data, braking data, ignition status data, or OBD-II fault code data.

19. A method for data access, comprising:

storing data associated with a plurality of vehicle event recorders using a server storage system;

including indications of server-stored data stored on the server storage system and corresponding client information in a global index, wherein the client information includes an indication that the stored data is associated with a client of a plurality of clients;

receiving, using an interface, an indication to access desired data associated with a vehicle event recorder of the plurality of vehicle event recorders, wherein the vehicle event recorder is associated with a specific client;

determining, using a processor, a server stored portion of the desired data associated with the vehicle event recorder that has been previously stored on the server storage system using information stored in the global index;

retrieving the server stored portion of the data from the server storage system; and

determining a non-server stored portion of the desired data associated with the vehicle event recorder that has not been previously stored on the server storage system using information stored in the global index and index, comprising:

looking up the desired data using information in a client index to determine the non-server stored portion of the desired data, wherein the client index comprises a plurality of client indices with an index associated with each client, wherein a first client index includes a subset of the indications of the global index corresponding to data associated with the first client;

determining whether all of the desired data was found in the client index; and

in response to a determination that all of the desired data was not found in the client index:

looking up the desired data using information in the global index to determine the non-server stored portion of the desired data, wherein the global index includes indications of server-stored data stored on the server storage system and corresponding client information, wherein the client information includes an associated indication that the server-stored data is associated with a client of a plurality of clients;
