This wizard is launched when a new Snapshot operation is added to a Policy.
The Snapshot operation is used to trigger snapshots of entire volumes. Multiple copies may be retained, enabling reversion to a specific point in time.
CAUTION:
- Snapshot operations always apply to the whole selected volume. Any associated data classifications are ignored.
- Snapshots will be automatically retired after the given retention period.

| Control | Description |
|---|---|
| Name | The name of the operation. The default name is 'Snapshot'. This is used to identify the operation when the policy is used in a Data Flow diagram and when operations are to be triggered sequentially. |
| Mode | This can currently only be set to:
|
| Hardware Type | Only enabled if Mode is set to Hardware. This can be set to:
|
| Run Options | Select one of the following:
|
| Select a Schedule | Enabled only when the Run Option is set to Scheduled. Enter an existing schedule name or select one from the dropdown menu. |
| Manage Schedules | Opens the Schedules Inventory in a new tab to enable you to add, edit, review or delete schedules. The times, dates and/or windows within which snapshots are created can be controlled by a named schedule that is then selected in the Schedule Name control. Once you have finished working in the Schedules tab, close it and return to the Snapshot Wizard. |
| Select Operation | Enabled only when the Run Option is set to Run on completion of operation. Enter an existing operation name or select one from the dropdown menu. This is used when a policy contains more than one operation and it is necessary that the operations occur in a sequential order. |
| Recovery Point Objective | This can be set to a specified period and is used in conjunction with the Run Options. If no schedules are defined (i.e. Run on RPO is selected), then a snapshot is created whenever the Recovery Point Objective time is reached. |
| Retention | The backup is retained for the specified period before being retired. |
| Quiesce configured applications before backup | This is used to ensure backup consistency. If this option is selected and any Application classifiers are included in the policy, these applications will be temporarily quiesced into a consistent state prior to the snapshot occurring. See About application quiescing. CAUTION:
|
| Pre Script | Specify a script that will be run before the snaphot is taken. This is used to ensure consistent state for applications other than those with a predefined Application Classification Wizard. |
| Post Script | Specify a script that will be run after the shapshot is taken. This is used to ensure consistent state for applications other than those with a predefined Application Classification Wizard. |
