Figure 21 Hierarchy tab
.
The following are represented in the hierarchy:
• The selected virtual disk—This is displayed even if no snapshot PiTs or snapshots are associated
with the virtual disk.
• PiTs associated with the virtual disk—A PiT created directly on the virtual disk appears as a child
node of the virtual disk. A PiT created on a snapshot appears as a child node of the snapshot.
• Any snapshots of any of the PiTs associated with the selected virtual disk — Each snapshot appears
as a child node of the PiT on which the snapshot was created.
If only the virtual disk itself is represented in the hierarchy, with no child nodes, no snapshot PiTs or
snapshots exist for the selected virtual disk.
