4. Select a virtual drive from the list of virtual drives in the Snapshot Repository
drop-down list.
This setting is the snapshot repository virtual drive. This drive stores the snapshot
data. Make sure you select a snapshot repository virtual drive with enough available
capacity. The available capacity is the largest free block of capacity on the selected
repository.
NOTE: A virtual drive and a snapshot repository virtual drive can be associated with the
same drives or a common set of drives, or the two virtual drives can be located on two
completely separate set of drives. Using a separate set of drives for the virtual drive and
the snapshot repository virtual drives provides a performance advantage over using a
common set of drives.
5. Click the Update Capacity button to determine the available capacity of the
selected repository.
CAUTION: Do not select the virtual drive containing the operating system as the
snapshot repository. Updates to the operating system crashes can destroy data on that
virtual drive.
