Tuning RMAN - RMAN Recipes for Oracle Database 12c - page 508

The prior output indicates that the RMAN backups took a little longer on August 10 (number 1 rank), but nothing
really out of the ordinary.
Refer to Table 16-1 for the view that you should inspect if you need to analyze backup performance information
on a more granular basis than what's available in V$RMAN_BACKUP_JOB_DETAILS. The view names in Table 16-1
are somewhat descriptive of each view's content. For example, if you want to analyze what is happening at the backup
set level, then V$BACKUP_SET or V$BACKUP_SET_DETAILS will provide information at that level. The recovery
catalog (RC) views are available only in your recovery catalog database. The RC views can be more valuable to you in
that they are capable of providing a longer history of information than the V$ views.
