Abstract
A system divides a source computer storage device into a plurality of logical volumes, and creates a first recovery point data file and a first recovery point index file. In response to an incremental backup of a first logical volume, the system creates a second recovery point index file comprising a plurality of indices. In response to no data changing in a particular block in the first logical volume, the system points an index in the second recovery point index file to the particular block in the first logical volume. In response to data changing in the particular block in the first logical volume, the system creates a corresponding new block in a second recovery point data file. The system points the index in the second recovery point index file to the corresponding new block in the first logical volume.
