Azure SQL备份
大家好，我们需要Microsoft代表的确认（官方MS文档很棒，但我们需要最新信息），Azure SQL备份存储时采用地理冗余类型，如果备份大小相等则可以免费使用数据库本身，
，如果我们设置28天的备份存储，我们将能够在28天内恢复到任何一天，
Hi guys, we need confirmation from Microsoft representative (official MS documentation is great but we need most recent info) that Azure SQL backups is being stored with the Geographically redundant type and it is free if size of backups is equal to db itself, and if we set 28 days of backup storing we will be able to restore to any day within 28 days,
祝你好运
Best regards
