Claims:WE CLAIM:
1. A method for restoring historic data of an enterprise, the method comprising:
receiving, by a data restoration system (101), a request from a user through a transformation backup server (103), for restoring historic data from a legacy storage device of a plurality of legacy storage devices (107), associated with an enterprise, along with metadata associated with the historic data, wherein the metadata is previously extracted and stored in a format recognizable by the transformation backup server (103);
determining, by the data restoration system (101), format of the historic data based on the metadata;
extracting, by the data restoration system (101), the historic data from the legacy storage device, using at least one of the metadata and a predefined execution process associated with the historic data, based on the format of the historic data; and
restoring, by the data restoration system (101), the extracted historic data to the user.

2. The method as claimed in claim 1, wherein the metadata comprises a job identification number and a media identification number of the historic data, a plurality of details associated with backed up data, files attributes, a time stamp and a plurality of encryption keys associated with the historic data, details of the legacy storage device from which historic data is requested and details of historic data requested, data format, and client details associated with the historic data.

3. The method as claimed in claim 1, wherein the format of the requested historic data comprises encrypted and standard format.

4. The method as claimed in claim 1, wherein storing the metadata associated with the historic data comprises:
obtaining, by the data restoration system (101), the metadata associated with the historic data, in a text format associated with a legacy backup server (108), based on a predefined native process of the legacy backup server (108);
converting, by the data restoration system (101), the metadata in the text format associated with the legacy backup server (108) to a metadata format recognizable by the transformation backup server (103); and
storing, by the data restoration system (101), the metadata obtained from the legacy backup server (108) in the transformation backup server (103) in the converted metadata format recognized by the transformation backup server (103).

5. The method as claimed in claim 1 further comprising updating status of the request to the transformation backup server (103) on restoring the requested historic data.

6. The data restoration system (101) for restoring historic data of an enterprise, comprising:
a processor (115); and
a memory (113) communicatively coupled to the processor (115), wherein the memory (113) stores processor instructions, which, on execution, causes the processor (115) to:
receive a request from a user through a transformation backup server(103), for restoring historic data from a legacy storage device of a plurality of legacy storage devices (107), associated with an enterprise, along with metadata associated with the historic data, from a transformation backup server (103), wherein the metadata is previously extracted and stored in a format recognizable by the transformation backup server (103);
determine format of the historic data based on the metadata;
extract the historic data from the legacy storage device, using at least one of the metadata and a predefined execution process associated with the historic data, based on the format of the historic data; and
restore the extracted historic data to the user.

7. The data restoration system (101) as claimed in claim 6, wherein the metadata comprises a job identification number and a media identification number of the historic data , a plurality of details associated with backed up data, files attributes, a time stamp and a plurality of encryption keys associated with the historic data, details of the legacy storage device from which historic data is requested and details of historic data requested, data format, and client details associated with the historic data.

8. The data restoration system (101) as claimed in claim 6, wherein the format of the requested historic data comprises encrypted and standard format.

9. The data restoration system (101) as claimed in claim 6, wherein the processor (115) stores the metadata associated with the historic data by:
obtaining the metadata associated with the historic data, in a text format associated with a legacy backup server (108), based on a predefined native process of the legacy backup server (108);
converting the metadata in the text format associated with the legacy backup server (108), to a metadata format recognizable by the transformation backup server (103); and
storing the metadata obtained from the legacy backup server (108) in the transformation backup server (103) in the converted metadata format recognized by the transformation backup server (103).

10. The data restoration system (101) as claimed in claim 6, wherein the processor (115) updates status of the request to the transformation backup server (103) on restoring the requested historic data.
