Abstract

Claims (56)

1. A method for managing data, the method comprising:

obtaining, by a universal connector (UC), a request for an incremental backup of a set of files;

in response to the request:

performing a metadata batching of the set of files to obtain a set of file batches;

generating a set of metadata requests each corresponding to one of the set of file batches,

wherein each of the set of metadata requests is converted to a format that is readable by a network attached storage (NAS) server to generate a set of converted metadata requests,

wherein the UC executes on a first computing device (CD) that comprises at least a first integrated circuitry (IC) that performs services for a second CD, wherein the NAS server is the second CD that comprises at least a second IC that provides services to the UC;

sending the set of converted metadata requests to the NAS server;

obtaining, in response to the set of converted metadata requests, a results array from the NAS server, wherein the results array comprises metadata of each file specified in the set of converted metadata requests;

comparing the metadata against an attributes table of the UC to determine a subset of changed files;

obtaining file data associated with the subset of changed files by sending a data access request to the NAS server;

initiating the incremental backup of the set of files using the file data; and

updating, based on the comparing, the attributes table to obtain an updated attributes table by updating a list of attributes associated with the subset of changed files.

2. The method of claim 1 , wherein the UC is operatively connected to a backup storage system, and wherein the incremental backup is stored in the backup storage system.

3. The method of claim 1 , wherein the NAS server is operatively connected to a NAS system.

4. The method of claim 1 , wherein the first CD is a production host.

5. The method of claim 3 , wherein the production host is operatively connected to the NAS via a network.

6. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing data, the method comprising:

obtaining, by a universal connector (UC), a request for an incremental backup of a set of files;

in response to the request:

performing a metadata batching of the set of files to obtain a set of file batches;

generating a set of metadata requests each corresponding to one of the set of file batches,

wherein each of the set of metadata requests is converted to a format that is readable by a network attached storage (NAS) server to generate a set of converted metadata requests,

wherein the UC executes on a first computing device (CD) that comprises at least a first integrated circuitry (IC) that performs services for a second CD, wherein the NAS server is the second CD that comprises at least a second IC that provides services to the UC;

sending the set of converted metadata requests to the NAS server;

obtaining, in response to the set of converted metadata requests, a results array from the NAS server, wherein the results array comprises metadata of each file specified in the set of converted metadata requests;

comparing the metadata against an attributes table of the UC to determine a subset of changed files;

obtaining file data associated with the subset of changed files by sending a data access request to the NAS server;

initiating the incremental backup of the set of files using the file data; and

updating, based on the comparing, the attributes table to obtain an updated attributes table by updating a list of attributes associated with the subset of changed files.

7. The non-transitory computer readable medium of claim 6 , wherein the UC is operatively connected to a backup storage system, and wherein the incremental backup is stored in the backup storage system.

8. The non-transitory computer readable medium of claim 6 , wherein the NAS server is operatively connected to a NAS system.

9. The non-transitory computer readable medium of claim 6 , wherein the first CD is a production host.

10. The non-transitory computer readable medium of claim 9 , wherein the production host is operatively connected to the NAS via a network.

11. A system comprising:

an application;

a network attached storage (NAS) server;

a processor; and

a universal connector (UC) operating on the processor,

wherein the UC is programmed to:

obtain a request for an incremental backup of a set of files;

in response to the request:

perform a metadata batching of the set of files to obtain a set of file batches;

generate a set of metadata requests each corresponding to one of the set of file batches,

wherein each of the set of metadata requests is converted to a format that is readable by the NAS server to generate a set of converted metadata requests,

wherein the UC executes on a first computing device (CD) that comprises at least a first integrated circuitry (IC) that performs services for a second CD, wherein the NAS server is the second CD that comprises at least a second IC that provides services to the UC;

send the set of converted metadata requests to the NAS server;

obtain, in response to the set of converted metadata requests, a results array from the NAS server, wherein the results array comprises metadata of each file specified in the set of converted metadata requests;

compare the metadata against an attributes table of the UC to determine a subset of changed files;

obtain file data associated with the subset of changed files by sending a data access request to the NAS server;

initiate the incremental backup of the set of files using the file data; and

update, based on the comparing, the attributes table to obtain an updated attributes table by updating a list of attributes associated with the subset of changed files.

12. The system of claim 11 , wherein the UC is operatively connected to a backup storage system, and wherein the incremental backup is stored in the backup storage system.

13. The system of claim 11 , wherein the NAS server is operatively connected to a NAS system.

14. The system of claim 11 , wherein the first CD is a production host.

15. The system of claim 14 , wherein the production host is operatively connected to the NAS via a network.
