Abstract

A method, non-transitory computer readable medium, and device that providing a unified storage for backup and disaster recovery includes capturing a recent snapshot of one or more file systems associated with a client computing device. The captured recent snapshot is stored in a secondary storage device. One or more changes to one or more files in the one or more file systems are determined by comparing the stored recent snapshot against an initial snapshot. A response to a disaster recovery request or a backup request based on the determined one or more changes to the one or more file systems is provided.

Claims

1. A method for providing a unified storage for backup and disaster recovery, the method comprising:

capturing, by a storage management computing device, a recent snapshot of one or more file systems associated with a client computing device;

storing, by the storage management computing device, the captured recent snapshot in a secondary storage device;

determining, by the storage management computing device, one or more changes to one or more files in the one or more file systems by comparing the stored recent snapshot against an initial snapshot; and

providing, by the storage management computing device, a response to a disaster recovery request or a backup request based on the determined one or more changes to the one or more file systems.

2. The method as set forth in claim 1 further comprising:

capturing, by the storage management computing device, the initial snapshot of the one or more file systems associated with the client computing device; and

storing, by the storage management computing device, the captured initial snapshot.

3. The method as set forth in claim 1 wherein, the determining the one or more changes further comprises:

obtaining, by the storage management computing device, only the determined one or more changes to the one or more files without the one or more file systems; and

storing, by the storage management computing device, the obtained one or more changes to the one or more files in the secondary storage device.

4. The method as set forth in claim 3 further comprising:

receiving, by the storage management computing device, the disaster recovery request from the client computing device;

obtaining, by the storage management computing device, one or more stored file systems associated with the client computing device based on information in the stored subsequent snapshot from the secondary storage device, the one or more stored file systems comprising only the obtained one or more changes to the one or more files; and

providing, by the storage management computing device, the obtained one or more stored file systems to the requesting client computing device.

5. The method as set forth in claim 3 further comprising:

receiving, by the storage management computing device, the backup request from the client computing device;

obtaining, by the storage management computing device, one or more stored backup file systems associated with the client computing device based on information in the stored initial snapshot and the stored subsequent snapshot from the secondary storage device, the one or more stored backup file systems comprising the obtained one or more changes to the one or more files and the one or more files without the obtained one or more changes; and

providing, by the storage management computing device, the obtained one or more stored backup file systems to the requesting client computing device.

6. A non-transitory computer readable medium having stored thereon instructions for providing a unified storage for backup and disaster recovery comprising executable code which when executed by a processor, causes the processor to perform steps comprising:

capturing a recent snapshot of one or more file systems associated with a client computing device;

storing the captured recent snapshot in a secondary storage device;

determining one or more changes to one or more files in the one or more file systems by comparing the stored recent snapshot against an initial snapshot; and

providing a response to a disaster recovery request or a backup request based on the determined one or more changes to the one or more file systems.

7. The medium as set forth in claim 6 further comprising:

capturing the initial snapshot of the one or more file systems associated with the client computing device; and

storing the captured initial snapshot.

8. The medium as set forth in claim 6 wherein, the determining the one or more changes further comprises:

obtaining only the determined one or more changes to the one or more files without the one or more file systems; and

storing the obtained one or more changes to the one or more files in the secondary storage device.

9. The medium as set forth in claim 8 further comprising:

receiving the disaster recovery request from the client computing device;

obtaining one or more stored file systems associated with the client computing device based on information in the stored subsequent snapshot from the secondary storage device, the one or more stored file systems comprising only the obtained one or more changes to the one or more files; and

providing the obtained one or more stored file systems to the requesting client computing device.

10. The medium as set forth in claim 8 further comprising:

receiving the backup request from the client computing device;

obtaining one or more stored backup file systems associated with the client computing device based on information in the stored initial snapshot and the stored subsequent snapshot from the secondary storage device, the one or more stored backup file systems comprising the obtained one or more changes to the one or more files and the one or more files without the obtained one or more changes; and

providing the obtained one or more stored backup file systems to the requesting client computing device.

11. A storage management computing device comprising:

a processor;

a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to;

capture a recent snapshot of one or more file systems associated with a client computing device;

store the captured recent snapshot in a secondary storage device;

determine one or more changes to one or more files in the one or more file systems by comparing the stored recent snapshot against an initial snapshot; and

provide a response to a disaster recovery request or a backup request based on the determined one or more changes to the one or more file systems.

12. The device as set forth in claim 11, wherein the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction comprising and stored in the memory to:

capture the initial snapshot of the one or more file systems associated with the client computing device; and

store the captured initial snapshot.

13. The device as set forth in claim 11, wherein the processor coupled to the memory is further configured to be capable of executing the programmed instructions further comprising and stored in the memory to determine the one or more changes further comprises:

obtain only the determined one or more changes to the one or more files without the one or more file systems; and

store the obtained one or more changes to the one or more files in the secondary storage device.

14. The device as set forth in claim 13, wherein the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction comprising and stored in the memory to:

receive the disaster recovery request from the client computing device;

obtain one or more stored file systems associated with the client computing device based on information in the stored subsequent snapshot from the secondary storage device, the one or more stored file systems comprising only the obtained one or more changes to the one or more files; and

provide the obtained one or more stored file systems to the requesting client computing device.

15. The device as set forth in claim 13, wherein the processor coupled to the memory is further configured to be capable of executing at least one additional programmed instruction comprising and stored in the memory to:

receive the backup request from the client computing device;

obtain one or more stored backup file systems associated with the client computing device based on information in the stored initial snapshot and the stored subsequent snapshot from the secondary storage device, the one or more stored backup file systems comprising the obtained one or more changes to the one or more files and the one or more files without the obtained one or more changes; and

provide the obtained one or more stored backup file systems to the requesting client computing device.
