Figure 79 Navigation window with shared snapshots
1. Original volume
2. Clone point
3. Shared snapshots
In Figure 79 (page 188) , the original volume is C#. Three snapshots were created from C#:
•
C#_snap1
•
C#_snap2
•
C#_SCsnap
Then a SmartClone volume was created from the latest snapshot, C#_SCsnap. That volume has a
base name of C#_class. The older two snapshots, C#_snap1 and C#_snap2, become shared
snapshots, because the SmartClone volume depends on the shared data in both those snapshots.
Table 54 How it works—shared snapshots
C# First, a volume
C#_snap1C#_snap2C#_SCsnap Next, 3 snapshots
C#class_x Finally, SmartClone volumes from the latest snapshot
Latest snapshot becomes clone point
Older two snapshots become shared between clone point
and SmartClone volume.
The shared snapshots also appear under all the volumes which share them. In Figure 79 (page 188) ,
they are displayed under the original volume from which they were created, and under the single
SmartClone volume that shares them. The selected shared snapshot is highlighted in the navigation
window, under both the volumes with which it is shared. Shared snapshots can be deleted.
