Note: Colors indicate where calls to a particular interface method will originate. For example, a method in the bridge API is green if the calls to that method are made from a Snapshot Storage Provider Task. A method in the bridge API is red if the calls to that method are made from Chronopolis. DuraCloud UI (DurAdmin)- <No additional API calls>
