Faster browse of secondary copies of block-level data volumes

A computer-implemented method for performing pre-processing operations to improve browse performance, the computer-implemented method comprising:

• receiving an indication that a secondary copy operation on a data volume is requested;
• parsing a master file table stored on the data volume to identify a first set of records of the master file table, wherein the master file table comprises the first set of records and a second set of records, wherein the first set of records comprises one or more file or folder records of the master file table and, when obtained in response to a request to browse a secondary copy of the data volume, are used to construct a user interface for browsing the secondary copy of the data volume, and wherein the second set of records comprises one or more reserved records of the master file table;
• transmitting primary data stored on the data volume and the first set of records, but not the second set of records, to a secondary storage computing device such that the secondary storage computing device generates the secondary copy of the data volume and a secondary copy of the first set of records and stores the secondary copy of the data volume and the secondary copy of the first set of records in a secondary storage device;
• receiving the request to browse the secondary copy of the data volume;
• and
• causing a restoration of the secondary copy of the first set of records for constructing the user interface.

A non-transitory computer-readable medium storing instructions, which when executed by a client computing device comprising physical hardware, cause the client computing device to perform a method comprising:

• receiving an indication that a secondary copy operation on a data volume is requested;
• parsing a master file table stored on the data volume to identify a first set of records of the master file table, wherein the master file table comprises the first set of records and a second set of records, and wherein the first set of records comprises one or more file or folder records of the master file table and, when obtained in response to a request to browse a secondary copy of the data volume, are used to construct a user interface for browsing the secondary copy of the data volume, and wherein the second set of records comprises one or more reserved records of the master file table;
• transmitting primary data stored on the data volume and the first set of records, but not the second set of records, to a secondary storage computing device such that the secondary storage computing device generates the secondary copy of the data volume and a secondary copy of the first set of records and stores the secondary copy of the data volume and the secondary copy of the first set of records in a secondary storage device;
• receiving the request to browse the secondary copy of the data volume;
• and
• causing a restoration of the secondary copy of the first set of records for constructing the user interface.

A networked information management system configured to perform post-processing operations to improve browse performance, the networked information management system comprising:

• a secondary storage computing device comprising first physical hardware;
• and
• a client computing device comprising second physical hardware that is in communication with the secondary storage computing device, wherein the client computing device is configured to:
• receive an indication that a secondary copy operation performed on a data volume is complete;
• request restoration of a secondary copy of a master file table stored in a secondary storage device in response to the secondary copy operation being performed, wherein the master file table is stored on the data volume;
• parse the restored master file table to identify a first set of records of the master file table, wherein the master file table comprises the first set of records and a second set of records, and wherein the first set of records comprises one or more file or folder records of the master file table and, when obtained in response to a request to browse a secondary copy of the data volume, are used to construct a user interface for browsing the secondary copy of the data volume, and wherein the second set of records comprises one or more reserved records of the master file table;
• transmit the first set of records, but not the second set of records, to the secondary storage computing device such that the secondary storage computing device generates a secondary copy of the first set of records and stores the secondary copy of the first set of records in the secondary storage device;
• receive the request to browse the secondary copy of the data volume;
• and
• cause a restoration of the secondary copy of the first set of records for constructing the user interface.
