ABSTRACT:
The present invention relates to a method of backup sampling of multiwritten storage volumes, by which the backup sampling time is remarkably reduced by taking advantage that the same storage region exists in a plurality of volumes. Data from storage regions differing with respect to respective storage volumes is inputted concurrently and parallel, and the data is outputted to the output volumes according to the following: (a) data are output to the output volumes in the order of these storage regions; (b) data with information indicative of the order of these storage regions are output to the output volumes in the order of the storage regions upon completion of its data input; and (c) data from respective storage regions are output to different corresponding output volumes concurrently and parallel.
