Techniques for performing an incremental restore from block-based backup are described herein. One method starts by parsing entries in first block allocation table (BAT) associated with first full backup information of parent volume to determine BAT entry corresponding to start of parent volume. Merged BAT associated with resultant image is then generated based on first BAT and incremental BATs respectively associated with one or more incremental backup information. One or more incremental backup information is based on incremental changes to parent volume subsequent to first full backup information being generated. Volume used blocks information is then generated based on merged BAT. Volume used blocks information includes start location of each volume used block. Starting from the entry corresponding to start of parent volume, data in blocks identified by each entry in merged BAT are read and written to target volumes corresponding respectively to each entry in merged BAT.
