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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 3) 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. ### Claim 5 (depends on 4) The method of claim 4, wherein the live mount connection request specifies the asset data file selection criterion. ### Claim 6 (depends on 4) The method of claim 4, wherein the asset data file selection criterion comprises a timestamp. ### Claim 7 (depends on 1) 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. ### Claim 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. ### Claim 9 (depends on 8) 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. ### Claim 10 (depends on 8) 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. ### Claim 11 (depends on 10) 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. ### Claim 12 (depends on 11) The system of claim 11, wherein the live mount connection request specifies the asset data file selection criterion. ### Claim 13 (depends on 11) The system of claim 11, wherein the asset data file selection criterion comprises a timestamp. ### Claim 14 (depends on 8) 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. ### Claim 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. ### Claim 16 (depends on 15) 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. ### Claim 17 (depends on 15) 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. ### Claim 18 (depends on 17) 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. ### Claim 19 (depends on 18) The non-transitory computer readable medium of claim 18, wherein the live mount connection request specifies the asset data file selection criterion. ### Claim 20 (depends on 18) The non-transitory computer readable medium of claim 18, wherein the asset data file selection criterion comprises a timestamp.
