Thank You. Our infra team is responsible for backup , stating that running
backup on primary is followed as a standard practice in our case. So
wondering if there exists any possible negative side of switching/running
the backup to DR side. Not fully clear though, but just thinking around
that in case of backup running on DR side. If a real disaster happens to
either side, will that cause any concern? or say while the lag is bigger
between primary and DR and one of the sides(say DR on which backup is
taking place) crashed , will that pose a threat for recovery?

We are using RMAN - ZDLRA for oracle database backup. We are running it
currently on Primary database and it runs for around 2hrs daily. We see
during the backup window there is higher IO utilisation and due to that
sometimes application query sees variable execution time.
We do have dataguard configured standby database for disaster recovery so
want to know from experts if it's advisable to run backup on standby side?
Or does it have any down side?
