amazon-web-services - RDS服务器备份

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 列:

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

这两个问题都与 S3 存储桶有关:

对于第一个问题，您正在备份的 s3 存储桶与您的 RDS 实例不在同一区域

对于第二个问题，Option 组中使用的角色没有相应存储桶的权限。转到安全凭证 -> 角色 -> 选择策略，然后进行编辑。
