The RESTful API method used to retrieve an existing configuration from a system like XtremIO is the HTTP GET methD.The GET method is used to request data from a specified resource and is one of the most common HTTP methods used in RESTful APIs1.

In the context of the XtremIO REST API, the GET method would be used to access various types of information about the array’s configuration.For example, to retrieve details about the volumes configured on an XtremIO array, you would issue a GET request to the appropriate endpoint of the XtremIO REST API2.

The HTTP POST method, on the other hand, is typically used to send data to the server to create or update a resource.The terms HTTP RETRIEVE and HTTP GATHER are not standard RESTful API methods and are not used in the context of the XtremIO REST API or any RESTful API1.

512 hours: This is calculated based on the system's capacity to handle hourly snapshots. For 15 volumes, taking snapshots every hour, the system can sustain this operation for approximately 512 hours until the maximum limit is reached.

XtremIO’s efficient snapshot management allows for a large number of snapshots without significant performance impact.
