初次使用数据灾备(DBS)时,您需要将角色权限(AliyunDBSDefaultRole)授权给数据灾备(DBS),并开通对象存储OSS,以允许DBS访问、查询和管理您的数据库,并将数据库实时备份到OSS。该授权操作是为了确保数据灾备(DBS)备份恢复服务的正常运行,对数据灾备(DBS)备份实例的性能不产生任何影响。
前提条件
已注册阿里云账号。具体操作,请参见注册阿里云账号。
步骤一:授权数据灾备(DBS)服务关联角色
数据灾备(DBS)服务关联角色(AliyunServiceRoleForDBS)是具备其他云服务访问权限的RAM角色,数据灾备(DBS)接入您在阿里云购买的云数据库(如RDS、MongoDB、 Redis、PolarDB)或阿里云ECS上自建的数据库时,需通过AliyunServiceRoleForDBS获取访问权限。更多信息,请参见服务关联角色。
初次使用数据灾备(DBS)时,您需要将服务关联角色(AliyunServiceRoleForDBS)授权给数据灾备(DBS)。权限详情,请参见附录:AliyunServiceRoleForDBS介绍。
- 登录数据管理DMS 5.0。
在顶部菜单栏中,选择
。说明若您使用的是极简模式的控制台,请单击控制台左上角的图标,选择
。在弹出的提示对话框中,单击授权DBS服务关联角色。
说明若登录数据灾备(DBS)控制台后,没有弹出提示授权的对话框,则无需执行本文后续操作,您可以开始创建备份。具体操作,请参见方式一:通过灾备数据源管理备份(推荐)或方式二:通过备份计划列表创建备份(限DBS老用户使用)。
单击确定。
此时,您已创建数据灾备(DBS)服务关联角色(AliyunServiceRoleForDBS),若您需要删除服务关联角色(AliyunServiceRoleForDBS),请参见删除RAM角色。
步骤二:开通对象存储OSS
开通对象存储OSS不会产生费用。开通后,您使用数据灾备(DBS)进行备份时,数据灾备(DBS)才能将备份数据存入OSS(云存储)中。
登录数据管理DMS 5.0。
在顶部菜单栏中,选择
。说明若您使用的是极简模式的控制台,请单击控制台左上角的图标,选择
。在弹出的提示对话框中,单击立即开通使用OSS。
在弹出的对话框中,单击立即开通。
在对象存储OSS页面,阅读并勾选服务协议,单击立即开通。
至此,您已开通数据灾备(DBS)服务。
