– Snapshot Repository Name – name of the new repository virtual disk
– Percent of Base Virtual Disk – percentage of the base virtual disk to use for the repository
– Disk Group – name of the disk group in which to place the repository virtual disk

NOTE: When the size of the snapshot exceeds the percentage of the base virtual disk, the snapshot fails. The
snapshot is no longer available for use until it is re-established by re-creating it. See the topic

Re-creating a

Legacy Snapshot

.

Disabling A Legacy Snapshot

To temporarily deactivate a snapshot so that it can be used again later, highlight the snapshot virtual disk in the Virtual
Disks tree and click Disable Snapshot. The snapshot process stops, but the relationship remains between the snapshot,
base virtual disk and repository virtual disks.

Re-Creating a Legacy Snapshot

To re-create a deactivated snapshot, click Recreate Snapshot. A new copy of the base virtual disk that can be used as
the snapshot is created.

NOTE: Re-creating a snapshot disables the original snapshot before the new snapshot is created.

Deleting A Legacy Snapshot

Select the snapshot virtual disk in the Virtual Disks tree and click Delete.

Point-In-Time Snapshots

The point-in-time (PiT) snapshot premium feature provides a method for creating an image of the base virtual disk used
to either revert back to or create a virtual disk copy of a point-in-time image that is presented to a host as read-only or
read-write. When PiT-based snapshots are enabled on the storage array, the Snapshots tab is shown in vCenter, see
figure PiT Snapshot View.

NOTE: Snapshot rollback and snapshot scheduling cannot be performed on the vCenter MD Plug-in. Both features
can only be configured in MD Storage Manager.
