You can either schedule updates or manually perform an update to transfer Snapshot copies between the source and destination SVMs. During the update, all the changes to data and configuration performed on the source SVM are replicated on the destination SVM.
The SnapMirror schedule is applicable to all the volumes and configuration of the source SVM.
