Catalog Backup Tune

Hello Experts,

We have a schedule in which full Catalog backup is happening daily and differential every 2-3 hours.

So do you suggest the same? We dont have many changes in a day. So do you really recommend that?

My understanding  is if we take daily full in the morning and cumulative in night is more than sufficient.

Pls share your understaning on Catalog backup schedules and recommendation.

Thanks,
