Datastax OpsCenter 5.2.0 无法备份到 Amazon S3

Question

当我使用 Opscenter 创建 Amazon S3 备份作业时，它会失败并在日志和浏览器中显示以下消息。它在创建步骤中失败了。我尝试了所有键空间和单个键空间...DSE 版本 4.7.1 .. Opscenter 版本 5.2.0。我刚刚创建了这个集群......并且是第一次创建备份作业。

请指教。

转到您的 cluter_name.conf 文件。在代理标题下（我想在您的情况下它是空白的），并添加以下行：

remote_backup_region = <region S3 bucket is in>

区域的适当值是：

us-standard 
us-west-1 
us-west-2 
eu-west-1
eu-central-1 
ap-northeast-1 
ap-southeast-1
ap-southeast-2
sa-east-1

保存该设置后，重新启动 OpsCenter 并再次尝试备份。
