SQL Server完整备份

完整备份；

A.备份到磁盘设备

USE AdventureWorks2012;
GO
BACKUP DATABASE AdventureWorks2012
TO DISK = 'Z:\SQLServerBackups\AdventureWorks2012.Bak'
   WITH FORMAT,
      MEDIANAME = 'Z_SQLServerBackups',
      NAME = 'Full Backup of AdventureWorks2012';
GO

B.备份到磁带设备

USE AdventureWorks2012;
GO
BACKUP DATABASE AdventureWorks2012
   TO TAPE = '\\.\Tape0'
   WITH NOINIT,
      NAME = 'Full Backup of AdventureWorks2012';
GO

C.备份到逻辑磁带设备

-- Create a logical backup device,
-- AdventureWorks2012_Bak_Tape, for tape device \\.\tape0.
USE master;
GO
EXEC sp_addumpdevice 'tape', 'AdventureWorks2012_Bak_Tape', '\\.\tape0'; USE AdventureWorks2012;
GO
BACKUP DATABASE AdventureWorks2012
   TO AdventureWorks2012_Bak_Tape
   WITH FORMAT,
      MEDIANAME = 'AdventureWorks2012_Bak_Tape',
      MEDIADESCRIPTION = '\\.\tape0',
      NAME = 'Full Backup of AdventureWorks2012';
GO

使用 PowerShell

A.完整的本地备份

Backup-SqlDatabase -ServerInstance Computer\Instance -Database MyDB -BackupAction Database

B.完整备份到 Microsoft Azure

import-module sqlps;
$container = 'https://mystorageaccount.blob.core.windows.net/myfirstcontainer';
$FileName = 'Sales.bak';
$database = 'Sales';
$BackupFile = $container + '/' + $FileName ;

Backup-SqlDatabase -ServerInstance "MyServer" -Database $database -BackupFile $BackupFile;

---------------------------------------------------------------------

备份文件和文件组

当数据库大小和性能要求使完整数据库备份显得不切实际，则可以创建文件备份。

A. 为两个文件创建文件备份

--Backup the files in the SalesGroup1 secondary filegroup.
BACKUP DATABASE Sales
   FILE = 'SGrp1Fi2',
   FILE = 'SGrp2Fi2'
   TO DISK = 'G:\SQL Server Backups\Sales\SalesGroup1.bck';
GO

B. 创建辅助文件组的完整文件备份

--Back up the files in SalesGroup1.
BACKUP DATABASE Sales
   FILEGROUP = 'SalesGroup1',
   FILEGROUP = 'SalesGroup2'
   TO DISK = 'C:\MySQLServer\Backups\Sales\SalesFiles.bck';
GO

C. 创建辅助文件组的差异文件备份

--Back up the files in SalesGroup1.
BACKUP DATABASE Sales
   FILEGROUP = 'SalesGroup1',
   FILEGROUP = 'SalesGroup2'
   TO DISK = 'C:\MySQLServer\Backups\Sales\SalesFiles.bck'
   WITH
      DIFFERENTIAL;
GO

使用 PowerShell

Backup-SqlDatabase -ServerInstance Computer\Instance -Database MyDB -BackupAction Files -DatabaseFileGroup "FileGroup1","FileGroup2"

----------------------------------------------------------------------------

差异备份；

-- Create a full database backup first.
BACKUP DATABASE MyAdvWorks
   TO MyAdvWorks_1
   WITH INIT;
GO
-- Time elapses.
-- Create a differential database backup, appending the backup
-- to the backup device containing the full database backup.
BACKUP DATABASE MyAdvWorks
   TO MyAdvWorks_1
   WITH DIFFERENTIAL;
GO
