Example 2
When source disks A (2GB) and B (4GB) are backed up in the first backup, and source disks C (2GB)
and D (2GB) are backed up in the second backup, Shadow Copy destination volumes A (2GB), B
(4GB), and C (2GB) are created as Shadow Copy destinations and these volumes are registered in the
backup disk pool management function.
In the first backup, Shadow Copy destinations A and B are automatically selected and used as Shadow
Copy destinations. In the second backup, Shadow Copy destinations A and C are automatically
selected and used as Shadow Copy destinations.
Example 3
Create the same number of Shadow Copy destination disks as the Shadow Copy sessions that are
executed concurrently and register these disks in the backup disk pool management function.
For example, when there are two partitions in a LUN and the shadow copies for these partitions are
executed separately, two Shadow Copy destination disks are required.
