Abstract

Systems and methods for storing data in a data storage system that allows dynamic context-based data protection and distribution are disclosed. The method includes receiving a storage request and evaluating whether a storage policy is specified in the storage request. When the storage request specifies a storage policy, the data is stored according to the specified policy. When the storage request does not specify a storage policy, meta data and/or the data item itself may be evaluated to identify a storage policy. When a storage policy has been identified, store the data is stored according to the identified policy. When a storage policy has not been specified and cannot be identified, an error is returned.

Claims

1. A computing device to manage a plurality of storage arrays of storage devices, the computing device comprising:

a processor;

a memory coupled with the processor;

a storage medium having instructions stored thereon which when executed cause the computing device to perform actions comprising;

evaluating whether a storage policy is specified in the storage request;

when the storage request specifies a storage policy, storing the data item according to the specified storage policy;

when the storage request does not specify a storage policy, evaluating whether the data item includes meta data;

when the data item includes meta data, inspecting the meta data to identify a storage policy;

when the data item does not include meta data, inspecting the data item to identify a storage policy;

wherein the inspecting the data item to identify a storage policy and inspecting the meta data include to identify a storage policy each include;

monitoring third party information sources for occurrences of key words,

evaluating a correlation between event data from the third party information sources and the key words,

deriving the storage policy based on the correlation evaluation;

storing the key words and the derived storage policy in a database;

when a storage policy has been identified, storing the data item according to the identified policy;

when a storage policy has not been identified, returning an error.

2. The computing device of claim 1 wherein each storage node includes a plurality of storage media.

3. The computing device of claim 2 wherein each storage node runs a local file system.

4. The computing device of claim 2 wherein the storage media are one or more selected from the group including hard disk drives, silicon storage devices and magnetic tape devices.

5. The computing device of claim 1 wherein the meta data includes at least one selected from the group including a source IP address, a destination IP address, an author name, a geographic location, a recipient name, a subject, a company.

6. The computing device of claim 1 wherein the computing device is at least one selected from the group including a storage server and a robust client.

7. The computing device of claim 1 wherein the storage medium has further instructions stored thereon which when executed cause the computing device to perform further actions comprising:

storing the object identifier and the meta data in a database.

8. A computing device to manage a plurality of storage arrays of storage devices, the computing device comprising:

a processor;

a memory coupled with the processor;

a storage medium having instructions stored thereon which when executed cause the computing device to perform actions comprising;

receiving from an application program a storage request to store a data item, the storage request including a data item reference;

evaluating whether a storage policy is specified in the storage request;

when the storage request specifies a storage policy, storing the data item according to the specified storage policy;

when the storage request does not specify a storage policy, evaluating whether the data item includes meta data;

when the data item includes meta data, inspecting the meta data to identify a storage policy;

when the data item does not include meta data or when a storage policy cannot be identified from the meta data, inspecting the data item to identify a storage policy;

wherein the inspecting the data item to identify a storage policy and inspecting the meta data include to identify a storage policy each include;

monitoring third party information sources for occurrences of key words,

evaluating a correlation between event data from the third party information sources and the key words,

deriving the storage policy based on the correlation evaluation;

storing the key words and the derived storage policy in a database;

when a storage policy has been identified, storing the data item according to the identified policy;

when a storage policy has not been identified, returning an error.

9. The computing device of claim 8 wherein each storage node includes a plurality of storage media.

10. The computing device of claim 9 wherein each storage node runs a local file system.

11. The computing device of claim 9 wherein the storage media are one or more selected from the group including hard disk drives, silicon storage devices and magnetic tape devices.
