属性值

An Int32 value that specifies the retention period in days. By default, the value is set to zero.

注释

Backup set retention period is set when media is initialized. When using SQL Server Management Objects (SMO) to automate Microsoft SQL Server backup, the RetainDays property is only evaluated when the Initialize property is True.
