By default, the tab displays the following information for each snapshot operation:

| ------------------ | --------------------------------------------------------------------- |
| Operation ID       | The ID of the operation.                                              |
| Command            | The operation performed: Create, Restore, and Delete.                 |
| Target snapshot ID | The snapshot ID.                                                      |
| Type               | The snapshot type: Full or Incremental.                               |
