RetainDays Property

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

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

語法

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);

備註

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.

Backup Object
