Abstract
Embodiments are directed to a method of performing block based backups for large-scale source volumes, by obtaining a total source volume size to determine if the source volume exceeds 64 TB, creating a number of sub-volumes to divide the total source volume into discrete sub-volumes of 64 TB each, and storing in an advanced file type device (AFTD), upon a read operation for a block based backup operation, each block of the source volume into a corresponding sub-volume of the sub-volumes. The method determines a block number and offset of each block and derives the corresponding sub-volume from the offset. Each sub-volume represents an individual saveset of the backup operation, and the container manages the individual saveset for the block based backup operation.
