Abstract
Consistently selecting a group of datasets during recovery, including: for each of a plurality of datasets: generating a respective identifier corresponding to a respective dataset, wherein the respective identifier is different from each other identifier; and storing the respective identifier to represent successful storage of the respective dataset; and responsive to recovering from a system interruption: extracting identifier information from all readable datasets; and generating, in dependence upon the extracted identifiers, a group of datasets from among the readable datasets.
