將數據庫的文件組備份還原到同一服務器上的另一個現有數據庫上

Question

我已經對SampleDB數據庫進行了文件組備份，我想將其還原到另一個現有的空數據庫RestoreDB 。 我能夠還原完整備份，但是還原文件組備份時遇到問題。

到目前為止，這是我嘗試過的。

RESTORE DATABASE RestoreDB
FROM DISK = 'D:\Sample\SampleDB_FileGroup.bak'
WITH    
    REPLACE,    -- Overwrite DB - if one exists
    NORECOVERY, -- Use if DIFFs / T/Logs to recover
--  RECOVERY,   -- Use if NO more files to recover, database will be set ready to use
    STATS = 10, -- Show progress (every 10%)
MOVE 'SampleDB' TO 'D:\Sample\RestoreDB\RestoreDB.mdf', 
MOVE 'SampleDB_2' TO 'D:\Sample\RestoreDB\RestoreDB_2.ndf',
MOVE 'SampleDB_log' TO 'D:\Sample\RestoreDB\RestoreDB_log.ldf'

使用上面的代碼，我能夠還原完整備份，但無法還原文件組備份。

關於如何實現這一目標的任何想法？

Answer 1

使用關鍵字PARTIAL還原PRIMARY文件組和所需的所有文件組，然后還原該文件組。

RESTORE DATABASE RestoreDB
FROM DISK = 'D:\Sample\SampleDB_FileGroup.bak'
WITH    
    REPLACE,    -- Overwrite DB - if one exists
    NORECOVERY, -- Use if DIFFs / T/Logs to recover
    STATS = 10, -- Show progress (every 10%)
    MOVE 'SampleDB' TO 'D:\Sample\RestoreDB\RestoreDB.mdf', 
    MOVE 'SampleDB_2' TO 'D:\Sample\RestoreDB\RestoreDB_2.ndf',
    MOVE 'SampleDB_log' TO 'D:\Sample\RestoreDB\RestoreDB_log.ldf',
    PARTIAL

Answer 2

我也嘗試過：

CREATE DATABASE [SampleDB] ON  PRIMARY 
( NAME = N'SampleDB', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\SampleDB.mdf' , SIZE = 3072KB , FILEGROWTH = 1024KB ), 
 FILEGROUP [FG2] 
( NAME = N'F2', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\F2.ndf' , SIZE = 3072KB , FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'SampleDB_log', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\SampleDB_log.ldf' , SIZE = 1024KB , FILEGROWTH = 10%)
GO

BACKUP DATABASE SampleDB
TO DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\BACKUP\backup1.bak' WITH INIT

BACKUP DATABASE SampleDB FILEGROUP = N'FG2'
TO DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\BACKUP\backup2.bak'

RESTORE DATABASE RestoreDB
FILEGROUP = N'PRIMARY'
FROM DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\BACKUP\backup1.bak'
WITH 
    MOVE N'SampleDB' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\RestoreDB.mdf',
    MOVE N'SampleDB_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\RestoreDB_log.ldf'    

RESTORE DATABASE RestoreDB
FILEGROUP = N'FG2'
FROM DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\BACKUP\backup2.bak'
WITH 
    MOVE N'F2' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\RestoreDB2.ndf'

但是我得到一個錯誤：

提供的備份與數據庫不在同一恢復路徑上，並且不適合用於在線文件還原。

我不知道，因為從來不需要這樣做，但是不可能移動它，Paul Randal在這里回答了這個問題： http : //www.sqlservercentral.com/Forums/Topic412470-357-1.aspx
