One example method includes receiving backup requests, creating a respective bitmap fragment for each backup request, each bitmap fragment corresponding to a respective tracking start time, for one of the requested backups, identifying a group of bitmap fragments that correspond to at timeframe extending from a time at which a previous backup was requested to a time at which the particular backup was requested, using the bitmap fragments of the group to create a consolidated bitmap that includes all changes to data in a volume resulting from IOs during the timeframe, with the consolidated bitmap, reading the data from the volume and transmit the data to a recipient, identifying new write IOs, received in parallel with transmission of the data, that are directed to data included in the particular backup, and reading, from the volume, the data to which the new write IOs are directed, and temporarily storing that data.
