Refreshing a VDB will re-provision it from the dSource. As with the normal provisioning process, you can choose to refresh the VDB from a snapshot or a specific point in time. However, you should be aware that refreshing a VDB would delete any changes that have been made to it over time. When you refresh a VDB, you are essentially re-setting it to the state you select during the refresh process. You can refresh a VDB manually, as described in this topic, or you can set a VDB refresh policy, as described in the topics Managing Policies: An Overview, Creating Custom Policies, and Creating Policy Templates.
Although the VDB no longer contains the previous contents, the previous Snapshots and TimeFlow still remain in Delphix and are accessible through the Command Line Interface (CLI).
