但是需要注意将SQL Server备份到Azure Storage需要确保数据库SQL Server 2012 SP1 CU2及以上版本。
说了这么多,下面我们就一起来看一下,如何将数据库备份到Azure Storage。
首先我们需要准备一个存储账户:
获取access key,本次示例中我们使用access key的方式访问存储账户:
使用如下T-SQL在SQL中创建账户:
IF NOT EXISTS(SELECT * FROM sys.credentials
WHERE credential_identity = ‘ bkuptour‘)
CREATE CREDENTIAL bkuptourl WITH IDENTITY = ‘sql12bak‘, SECRET = ‘5amfZJpKLcR2lAfEBZod18VYbxZOPUbtKH9RowDQ3Ixv5sGMnSj5Lo/UbPb/zCCRKh/kAxnOaOS9oJELTVVoTg==‘;
创建完成后我们可以在存储账户中创建一个container用来存储备份文件:
创建完成以后可以使用如下T-SQL将数据库备份到Storage Account中:
DECLARE @DB_name VARCHAR(50) -- database name
DECLARE @BackupLoc VARCHAR(256) -- path for backup files
DECLARE @BackupfileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
-- specify database backup container location
SET @BackupLoc = ‘https://sql12bak.blob.core.chinacloudapi.cn/test/‘
set @fileDate= replace(replace(convert(nvarchar(50),getdate()),‘ ‘,‘_‘),‘:‘,‘_‘)
DECLARE db_cursor CURSOR FOR
SELECT name FROM master.sys.databases WHERE database_id <>2 and state=0
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @DB_name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @BackupfileName = @BackupLoc + @DB_name + ‘_‘ + @fileDate + ‘.BAK‘
BACKUP DATABASE @DB_name TO URL = @BackupfileName WITH CREDENTIAL = ‘bkuptourl‘,COMPRESSION
print ‘BACKUP DATABASE ‘+@DB_name+ ‘ TO URL =‘‘‘+ @BackupfileName +‘‘‘ WITH CREDENTIAL = ‘‘bkuptourl‘‘,COMPRESSION ‘
FETCH NEXT FROM db_cursor INTO @DB_name
END
CLOSE db_cursor
DEALLOCATE db_cursor
备份完成,如下图所示:
