One subtlety: If you plan to perform incremental backups on the
DataGuard standby database, and if you plan to use a block-change
tracking (BCT) file on the standby to optimize those incremental
backups, then using a BCT file on a DataGuard standby requires an
*Active *DataGuard license. Search for the text "block change tracking"
HERE
<https://www.oracle.com/database/technologies/faq-active-data-guard.html>.
Of course, some may say, "/standby is not production so BCT is not
needed/", but incremental backups without BCT on very large databases
can overrun timeslots, so that decision should be made on a case-by-case
basis.

ADG is not required, however you must use an rman catalog in order to do it.

I have been asked if we can create a standby and do backups from
there instead of through Commvault while they do some storage
conversions. I have read conflicting information as to whether or
not Active Data Guard is required to run backups from the
standby. I can't open a ticket with Oracle to ask the question
since management saw fit to cancel our support. If someone could
point me in the right direction, that would be great. Also, we do
not use a catalog for our backups.
Thank you,
