ABSTRACT:
A system and method for generating persistent consistency point images (PCPIs) is provided. A first set of statistics is obtained for a plurality of data containers. The PCPIs are generated for each of the plurality of data containers after the first set of statistics is obtained. A second set of statistics is obtained for the plurality of data containers after the PCPIs are generated. It is determined that modifying operations were performed to a data container while generating the PCPIs if the first and the second set of statistics are not equal, and it is determined that no modifying operations were performed to the data container while generating the PCPIs if the first and the second set of statistics are equal. The PCPIs are stored on a storage device in response to determining that no modifying operations were performed to the data container while generating the PCPIs.
