Abstract
In one aspect, a method includes storing data in a distributed storage environment that includes data servers and configuring each data server to mark a respective bit map for each block of data changed. In another aspect, an apparatus includes electronic hardware circuitry configured to store data in a distributed storage environment that includes data servers and to configure each data server to mark a respective bit map for each block of data changed. In a further aspect, an article includes a non-transitory computer-readable medium that stores computer-executable instructions. The instructions cause a machine to store data in a distributed storage environment that includes data servers and configure each data server to mark a respective bit map for each block of data changed. In each of the aspects above each data server is configured to handle a respective portion of a logical unit.
