Database Backups with Always ON

Hi,

I have a SQL 2012 Always on environment set up for our new system. The Configuration is
Primary Node A,
Replica Node B
Asynchronous AG set up between nodes A => B.

What is the best strategy to set up database backups. In order to keep one week of changes available for any restore I am thinking to setting up following plan

Weekly Full Back on Sunday [10 AM] -> Set up on Primary Node A

Daily Deferential backup after close of business in the evening [12 PM] -> Set up on Primary Node A

Regular transaction log backup during business hours [8 AM-7 PM] -> Set up on Replica Node B

Thanks in advance
