Abstract
The Dynamically Determined Difference Regions Apparatuses, Methods and Systems (“DDDR”) transforms backup configuration request, backup data read response inputs via DDDR components into backup configuration response, changed blocks update request outputs. A write command for a data block to write to a data volume is detected. A data volume address of the data block is determined. A superset range associated with the data volume address is determined. Upon determining that the written-to flag of the superset range is set: extend a previously established written-to subset range within the superset range to include the data volume address when it is determined that the data volume address is not within the previously established written-to subset range. Upon determining that the written-to flag is not set: set the written-to flag and establish a new written-to subset range within the superset range that includes the data volume address. Execute the write command.
