RetainDays Property

后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The RetainDays property specifies the number of days that must elapse before a backup set can be overwritten.

语法

object
.RetainDays [= value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    A long integer that specifies a number of days

Data Type

Long

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetRetainDays(LPLONG pRetVal);
HRESULT SetRetainDays(long NewValue);

注释

For Microsoft SQL Server, backup set retention period is set when media is initialized. If SQL Distributed Management Objects (SQL-DMO) is used to automate SQL Server backup, the RetainDays property is only evaluated if the Initialize property is TRUE.
