Question

意图是导出RDS并将数据加载到本地mssql DB。

尝试备份rds服务器时出现以下错误。

用于启动的SQL语句：

USE [msdb]
GO
DECLARE   @return_value int
EXEC  @return_value = [dbo].[rds_backup_database]
      @source_db_name = 'abcd',
      @S3_arn_to_backup_to = 'arn:aws:s3:::abcd/test_09_May.bak',
      @KMS_master_key_arn = NULL,
      @overwrite_S3_backup_file = NULL
SELECT    'Return Value' = @return_value
GO

查询状态：

exec msdb.dbo.rds_task_status
EXEC msdb.dbo.rds_task_status 
    @db_name = 'abcd', -- sysname
    @task_id = 7 -- int
exec msdb.dbo.rds_task_status @task_id = 7
exec msdb.dbo.rds_task_status @db_name='abcd'

失败原因 - taskinfo专栏：

1. Aborted the task because of a task failure or an overlap with your preferred backup window for RDS automated backup.
A WebException with status ConnectFailure was thrown.

2. Aborted the task because of a task failure or an overlap with your preferred backup window for RDS automated backup.
Access Denied

Answer 1

这个问题都与S3存储桶有关：

对于第一个问题，您要备份的s3存储桶与RDS实例不在同一区域

对于第二个问题，Option组中使用的角色对相应的存储桶没有权限。转到安全凭证 - ＆gt;角色 - ＆gt;选择策略，然后进行编辑。

Answer 2

我建议您使用数据库导出，RDS不允许在AWS环境之外导出。
