CONCURRENT TRANSMISSION OF MULTIPLE EXTENTS DURING BACKUP OF EXTENT-ELIGIBLE FILES

Abstract:

An information management system supports the concurrent transfer of multiple extents from a client computing device having one or more files stored in a primary storage device. The client computing device determines whether one or more of the files are extent-eligible by comparing a file size of a file with a predetermine file size threshold. Based on the comparison, the client computing device determines that the file is extent-eligible, and determines a plurality of extents for the extent-eligible file. The client computing device may then concurrently transmit one or more of the extents of the extent-eligible file to one or more nodes in communication with the client computing device. The one or more nodes may index the received extents for later retrieval during a restore operation of the extent-eligible file. The one or more nodes may also validate the extents to ensure that the extents are not corrupted.
