SYSTEM AND METHOD FOR FACILITATING ELECTRONIC DISCOVERY
A method for facilitating discovery of electronic data stored in a data storage system. The method includes generating a snapshot of the electronic data, wherein the snapshot permits read access to the data, and a copy-on-write technique is used to perform modifications to the data, such that the snapshot is immutable but ongoing user operations with respect to the data can be performed substantially without interruption. The method also includes transmitting data of the snapshot over a network to a data cache server to which an analysis computer system is communicatively coupled. In some embodiments, the data cache server may store a local copy of the transmitted data of the snapshot. In this regard, the data cache server may determine whether data requested by the analysis computer system is stored locally, and if so, the data cache server may transmit the data requested directly to the analysis computer system.
1 . A method for facilitating discovery of electronic data stored in a data storage system, the method comprising:
generating a snapshot of the electronic data, wherein the snapshot permits read access to the data, and a copy-on-write technique is used to perform modifications to the data, such that the snapshot is immutable but ongoing user operations with respect to the data can be performed substantially without interruption; and
providing access to the snapshot of the electronic data to an analysis computer system.
2 . The method of claim 1 , wherein providing the access to the snapshot is provided over a network.
3 . The method of claim 2 , wherein the analysis computer system is remote from the data storage system.
4 . The method of claim 2 , wherein providing the access to the snapshot comprises transmitting data of the snapshot over the network to a data cache server to which the analysis computer system is communicatively coupled.
5 . The method of claim 4 , wherein the data of the snapshot is transmitted upon request from the data cache server.
6 . The method of claim 5 , further comprising storing a local copy of the transmitted data of the snapshot at the data cache server.
7 . The method of claim 4 , further comprising generating a security key required for accessing the snapshot data and transmitting the security key to the data cache server.
8 . The method of claim 4 , wherein transmitting data of the snapshot over the network comprises transmitting the data utilizing a block-based protocol.
9 . The method of claim 6 , further comprising receiving a request for particular data of the snapshot from the analysis computer system at the data cache server.
10 . The method of claim 9 , further comprising determining whether the data requested by the analysis computer system is stored locally at the data cache server and if the data requested by the analysis computer system is stored locally at the data cache server, transmitting the data requested by the analysis computer system from the data cache server to the analysis computer system.
11 . The method of claim 10 , wherein if the data requested by the analysis computer system is not stored locally at the data cache server, transmitting data of the snapshot, corresponding to the data requested by the analysis computer system, over the network to the data cache server.
12 . The method of claim 11 , further comprising encrypting the data of the snapshot for transmission over the network.
13 . An information handling system comprising:
a data storage site comprising a data storage system and a system controller, the system controller communicatively coupled with the data storage system and managing access to the data storage system by one or more user computer systems, the system controller further managing a snapshot of data of the data storage system, wherein the snapshot permits read access to the corresponding data, and the system controller utilizes a copy-on-write technique to perform modifications to the corresponding data, such that the snapshot is immutable but ongoing input/output (I/O) requests from the one or more user computer systems with respect to the data are performed substantially without interruption; and
an e-discovery site comprising a data cache server and one or more analysis computer systems communicatively coupled with the data cache server, wherein the system controller and data cache server are communicatively coupled via a computer network;
wherein, upon request from the data cache server, the system controller provides access to the snapshot of data.
14 . The information handling system of claim 13 , wherein the system controller and data cache server are remotely connected via the computer network.
15 . The information handling system of claim 14 , wherein, upon request from the data cache server, the system controller transmits data of the snapshot over the network.
16 . The information handling system of claim 15 , wherein the data cache server stores a local copy of the transmitted data of the snapshot.
17 . The information handling system of claim 14 , wherein the data cache server is configured to receive requests for particular data of the snapshot from the one or more analysis computer systems.
18 . The information handling system of claim 17 , wherein, for each request received from the one or more analysis computer systems, the data cache server is configured to determine whether the data requested is stored locally at the data cache server and based on the determination, fulfill the request locally or request data from the system controller.
19 . The information handling system of claim 17 , wherein data transmitted by the system controller is encrypted.
20 . The information handling system of claim 17 , wherein data transmitted by the system controller follows a block-based protocol.
