I'm trying to create a Mirror and Vault Protection Relationship but I'm a little confused. When creating the Protection Relationship, why do I need to choose a Mirror and Vault Policy and a Schedule when my custom Mirror and Vault Protection Policiy (to-SAS) already includes the schedules (hourly and daily)? Furthermore, I can only choose one schedule but my custom Mirror and Vault Protection Policy includes two schedules (hourly and daily). What am I missing?
