Configure Backup on Secondary Replica.
AlwaysOn Hish Availability Groups provides Backup on Secondary database to overcome load on Primary Database.
As Secondary database is Read-Only replica so you can’t execute any code directly, you need to create Maintenance Plan for backup.
AlwaysOn High Availability Groups only Provides “Copy-Only Backup” at Secondary replica, it means differential backup is not available at secondary replica.
