Found my answer, I shall share.....

MS does not care where you backup your database however with AlwaysOn you can only backup one. The Primary or Secondary, your choice. Here’s the catch, you choose which one based on whether you want to offload resources. Let’s say that you have a 24X7 database, it would make sense to place it on the secondary. If is not a 24X7 database then you can use the golden DBA rule and run the backup at night on the primary.

Maint. Jobs -- only on the primary. You set up jobs on the secondary in case of a failover. They will run and say success even though they are not doing anything at all.
