backup with always on cluster

I am setting up a new alwayson cluster sql2014. there are no shared disks. the secondaries are set up to allow read access

i have several user databases set up and seem to be working ok

i want to set up jobs to backup the user databases and the system databases. they need to run on each server just in case one server fails. 

1. how do I set up jobs for full and transnational backups on each server performing one backup and not one backup per server in the cluster when the job runs on each server? I have set up a cluster connection to the listener address and preferred the secondary server as the backup source.

2. the master and msdb databases are not part of the always on cluster. how do I back them up on each node? trying to connect to the local server has the backup failing with 

???
