Osservazioni

Data is retained for the period specified by the RetentionAge element, although it is not necessarily removed immediately upon expiration of the specified period. When the data removal process runs, it attempts to delete event and notification data that is older than the retention age.

The format of the XML duration data type is PnYnMnDTnHnMnS. For more information about XML data types, see Primitive XML Data Types in the Microsoft MSDN® Library.

The following example shows how to set a retention age of 2 days.
