LastBackup 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 LastBackup property identifies the most recent date and time at which a backup operation was performed against the referenced transaction log.

Prototype (C/C++)

HRESULT GetLastBackup(SQLDMO_LPBSTR pRetVal);

注意：
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

备注

The LastBackup property date is reported as a string, formatted as yyyy**/mm/dd hh:mn:ss.**fff where yyyy represents the year in four digits; mm represents the month in two digits; dd represents the day in two digits; hh represents the hour in two digits using a twenty-four hour clock; mn represents the minute in two digits; ss represents the second in two digits; and fff represents the thousandth of a second in three digits.
