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?
The "-schedule" parameter in your custom policy is not a transfer schedule and will not transfer Snapshot copies with the SnapMirror label whatever chosen "label" from the source. Specifying the "-schedule" parameter will only enable independent scheduled Snapshot copy creation on the destination with whatever SnapMirror "label".
To determine actual 'transfer-schedule' do this: ::> snapmirror show -destination-path vserver: destination-path Policy: custom SnapMirror Schedule: <schedule> <--Look for this (This is the one mentioned in your screenshot as hourly)
The other schedule is 'non-transfer schedule' (which is part of the Policy): ::> snapmirror policy show -policy custom
If I specify a schedule in the Protection Relationship, then it will take snapshots of the source based on that schedule. These snapshots will not be created on the source and then transferred to the destination, rather they will only be created on the destination.
If I do not specify a schedule in the Protection Relationship, then it will take snapshots of the source based on the Protection Policy schedule. These snapshots will be created on the source and then backed up to the destination.
