"How SnapVault backups work". The guide states
"You can back up data from a specific qtree or from an entire volume... When you back up a volume
ONTAP creates a qtree for the volume on the destination." This confirms the qtree as the fundamental container on the destination.

Section 2.2 "SnapVault". It describes
"SnapVault is a backup technology that creates a Snapshot copy of a specified qtree or volume on the primary system and copies it to a qtree on the secondary system." This explicitly identifies the qtree as the operational unit.

"Create a SnapVault relationship"
Command reference for snapmirror create. The syntax requires specifying a source path that can be a volume or qtree
and a destination path that is a qtree. For example: -source-path SVM:volume/qtree -destination-path SVM:volume/qtree. This demonstrates the qtree as the core component in the relationship definition.
