摘要: A CPU implemented method for managing the backup copying of data sets residing in non-volatile storage and recovery thereof event failure. The first step is to invoke a modified incremental copy policy using small window less than that heretofore used full, or mixed policies. That is, made designated part only those group satisfying pair adjustable parameters relating last date, update, current date. second occurs during cycle failure wherein backed up datasets are copied from said into storage.
