Abstract

Claims (22)

1. A storage management system operatively coupled to a storage system, the storage management system comprising:

a plurality of processor modules, each processor module to intercept write commands directed to the storage system, generate backup data based upon data associated with the write commands, and generate metadata having timestamps for the backup data; and

one or more indexing modules to create one or more indexing tables for the backup data based on the metadata, wherein the one or more indexing modules are located separate from the plurality of processor modules to allow separate scalability of the plurality of processor modules and the one or more indexing modules, wherein the one or more indexing modules are in communication with the plurality of processor modules and the storage system, wherein the one or more indexing modules further perform one or more functions associated with one or more functional modules selected from the group consisting of a blade configuration manager, a remap engine, a global database, a production restore, a timeline compression, an indexing database interface, a metadata space manager, and vendor multipathing software.

2. The storage management system according to claim 1 , wherein the number of the plurality of processor modules is scalable based on a desired capacity of the storage management system.

3. The storage management system according to claim 1 , wherein the plurality of processor modules are configured with fault-tolerant redundancy.

4. The storage management system according to claim 1 , wherein the plurality of processor modules are coupled to the storage system via fiber connections.

5. The storage management system according to claim 1 , wherein each of the plurality of processor modules comprises at least one target interface and at least one initiator interface.

6. The storage management system according to claim 1 , wherein the plurality of processor modules are in communication with one another.

7. The storage management system according to claim 1 , wherein the number of the one or more indexing modules is scalable based on the number of the plurality of processor modules to be supported by the one or more indexing modules.

8. The storage management system according to claim 1 , wherein the one or more indexing modules have direct access to one or more metadata storage devices in the storage system via fiber connections.

9. The storage management system according to claim 1 , wherein the one or more indexing modules communicate with the plurality of processor modules via one or more internal networks.

10. The storage management system according to claim 1 , wherein the one or more indexing modules communicate with the plurality of processor modules through a plurality of agents and proxies.

11. A method for improving portability and scalability of a storage management system operatively coupled to a storage system, the method comprising:

coupling a plurality of processor modules to the storage system, each processor module to intercept write commands directed to the storage system, generate backup data based upon data associated with the write commands, and generate metadata having timestamps for the backup data;

coupling a blade farm having one or more indexing modules to the storage system, wherein the blade farm is located separate from the plurality of processor modules to allow separate scalability of the plurality of processor modules and the one or more indexing modules, wherein the blade farm is in communication with the plurality of processor modules and the storage system; and

causing the blade farm to communicate with the plurality of processor modules via one or more internal networks, wherein the one or more indexing modules create one or more indexing tables for the backup data based on the metadata, wherein the one or more indexing modules further perform one or more functions associated with one or more functional modules selected from the group consisting of a blade configuration manager, a remap engine, a global database, a production restore, a timeline compression, an indexing database interface, a metadata space manager, and vendor multipathing software.

12. At least one processor readable storage medium for storing a computer program of instructions configured to be readable by at least one processor for instructing the at least one processor to execute a computer process for performing the method as recited in claim 11 .

13. A method for improving portability and scalability of a storage management system operatively coupled to a storage system, the method comprising:

intercepting, at a plurality of processor modules, write commands directed to the storage system;

generating backup data based upon data associated with the write commands;

generating metadata having timestamps for the backup data; and

creating, at one or more indexing modules, one or more indexing tables for the backup data based on the metadata, wherein the one or more indexing modules are located separate from the plurality of processor modules to allow separate scalability of the plurality of processor modules and the one or more indexing modules, wherein the one or more indexing modules are in communication with the plurality of processor modules and the storage system, wherein the one or more indexing modules further perform one or more functions associated with one or more functional modules selected from the group consisting of a blade configuration manager, a remap engine, a global database, a production restore, a timeline compression, an indexing database interface, a metadata space manager, and vendor multipathing software.
