5.4.1.3 HSBBAC Usage Considerations

This section identifies one special consideration or
technique related to using the HSBBAC file.

Note that data element BACALLSP at the DETAIL timespan
contains the amount of space occupied by all backup versions
of a data set.  Unlike most other CA MICS files at the DETAIL
timespan, the HSBBAC file has already gone through a level of
summarization.  Rather than an observation for each data set
backup version, there is one observation per data set,
containing information relevant to all data set backup
versions.
