generating a directory;
populating the directory with a backup control file image and a plurality of pointers to backup data file images in a second directory, wherein the backup control file image is obtained from the second directory;
restoring at least a portion of the backup data file images in the directory using the backup control file image and at least a portion of the backup data file images in the second directory;
providing after the restoring, a handle to the directory to the client device.
2. The method of claim 1 , further comprising:
prior to receiving the live mount connection request:
obtaining the backup data file images from the client device;
obtaining the backup control file image from the client device; and
storing the backup data file images and the backup control file image in the second directory.
3. The method of claim 1 , wherein restoring at least the portion of the backup data file images in the directory using the backup control file image and at least the portion of the backup data file images in the second directory comprises:
restoring backup control files the backup control file image, wherein restoring at least the portion of the backup data file images in the directory comprises using the backup control files.
4. The method of claim 3 , wherein restoring at least the portion of the backup data file images in the directory using the backup control file image and at least the portion of the backup data file images in the second directory comprises further comprises:
obtaining asset data file selection criterion from the client device, wherein restoring at least the portion of the backup data file images in the directory further comprises using the asset data file selection criterion.
5. The method of claim 4 , wherein the live mount connection request specifies the asset data file selection criterion.
6. The method of claim 4 , wherein the asset data file selection criterion comprises a timestamp.
7. The method of claim 1 , wherein the live mount connection request specifies a directory path to the backup data file images, wherein the directory path corresponds to the second directory.
8. A system, comprising:
a processor;
a backup mounting agent, which when executed by the processor performs a method, the method comprising:
receiving a live mount connection request from a client device;
in response to the live mount connection request:
generating a directory;
populating the directory with a backup control file image and a plurality of pointers to backup data file images in a second directory, wherein the backup control file image is obtained from the second directory;
restoring at least a portion of the backup data file images in the directory using the backup control file image and at least a portion of the backup data file images in the second directory;
providing, after the restoring, a handle to the directory to the client device.
9. The system of claim 8 , wherein the method further comprises:
prior to receiving the live mount connection request:
obtaining the backup data file images from the client device;
obtaining the backup control file image from the client device; and
storing the backup data file images and the backup control file image in the second directory.
10. The system of claim 8 , wherein restoring at least the portion of the backup data file images in the directory using the backup control file image and at least the portion of the backup data file images in the second directory comprises:
restoring backup control files the backup control file image, wherein restoring at least the portion of the backup data file images in the directory comprises using the backup control files.
11. The system of claim 10 , wherein restoring at least the portion of the backup data file images in the directory using the backup control file image and at least the portion of the backup data file images in the second directory further comprises:
obtaining asset data file selection criterion from the client device, wherein restoring at least the portion of the backup data file images in the directory further comprises using the asset data file selection criterion.
12. The system of claim 11 , wherein the live mount connection request specifies the asset data file selection criterion.
13. The system of claim 11 , wherein the asset data file selection criterion comprises a timestamp.
14. The system of claim 8 , wherein the live mount connection request specifies a directory path to the backup data file images, wherein the directory path corresponds to the second directory.
15. 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 accessing backup data, the method comprising:
receiving a live mount connection request from a client device;
in response to the live mount connection request:
generating a directory;
populating the directory with a backup control file image and a plurality of pointers to backup data file images in a second directory, wherein the backup control file image is obtained from the second directory;
restoring at least a portion of the backup data file images in the directory using the backup control file image and at least a portion of the backup data file images in the second directory;
providing, after the restoring, a handle to the directory to the client device.
16. The non-transitory computer readable medium of claim 15 , wherein the method further comprises:
prior to receiving the live mount connection request:
obtaining the backup data file images from the client device;
obtaining the backup control file image from the client device; and
storing the backup data file images and the backup control file image in the second directory.
17. The non-transitory computer readable medium of claim 15 , wherein restoring at least the portion of the backup data file images in the directory using the backup control file image and at least the portion of the backup data file images in the second directory comprises:
restoring backup control files the backup control file image, wherein restoring at least the portion of the backup data file images in the directory comprises using the backup control files.
18. The non-transitory computer readable medium of claim 17 , wherein restoring at least the portion of the backup data file images in the directory using the backup control file image and at least the portion of the backup data file images in the second directory further comprises:
obtaining asset data file selection criterion from the client device, wherein restoring at least the portion of the backup data file images in the directory further comprises using the asset data file selection criterion.
19. The non-transitory computer readable medium of claim 18 , wherein the live mount connection request specifies the asset data file selection criterion.
20. The non-transitory computer readable medium of claim 18 , wherein the asset data file selection criterion comprises a timestamp.
