Abstract
For facilitating data verification using a checksum in conjunction with a sidefile by a processor device in a computing environment, first block signatures having a first size are calculated for first blocks of a first volume stored on a storage device. The first block signatures are stored to a sidefile. Second block signatures having a second size different from the first size are calculated for second blocks of a second volume stored on the storage device. The second block signatures are stored to the sidefile.

7. A computer program product for facilitating data verification using a checksum in conjunction with a sidefile by at least one processor device, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
-
a first executable portion for calculating, for first blocks of a first volume stored on a storage device, first block signatures having a first size; a second executable portion for storing the first block signatures to the sidefile; a third executable portion for calculating, for second blocks of a second volume stored on the storage device, second block signatures having a second size different from the first size; and a fourth executable portion for storing the second block signatures to the sidefile. - View Dependent Claims (8, 9, 10, 11, 12)
