5.4.1 BACKUP Data File (HSBBAC)

At the DETAIL timespan, this file describes a variety of
information about the DFHSM-managed backup versions for a
given data set at a given point in time.

Records created by VCC are at the backup version level. That
is, there is one raw record for each backup version in the
inventory maintained by DFHSM. The DAY095 processing reduces
multiple backup versions for a data set into one observation
for that data set. The fact that this summarization is done
in the DETAIL timespan is a slight departure from most
CA MICS DAILY processing. It keeps the size of the DETAIL
timespan manageable while still offering full reporting
capability.

The summarization that takes place from DETAIL to DAYS then
eliminates DSNAME as a sequence variable and reduces
the data regarding backup resources to the account structure
or cost center variables.

The following sections describe the file's organization, list
the data elements maintained, and provide usage hints.
