B |     (ECNS) --“Going global” has emerged as one of the key themes of the 2026 World Robot Conference, which is being held in Beijing from Aug. 19 to 23.    At the booth of Beijing-based Yunji Technology, visitors can explore a range of practical applications, including smart hotel services, automated laundry retail cabinets, latte art coffee stations and freshly cooked noodle stations.        Yunji Technology Chief Product Officer Duan Yanbiao told China News Service that the company’s robots have already been deployed in more than 20 countries and regions, covering major markets across Southeast Asia, Japan and South Korea, the Middle East, Europe and the United States. The company serves more than 40,000 corporate customers, while revenue from its overseas business surged by more than 90% last year.    Another Chinese robotics company, Leju Robotics, said it began expanding overseas around 2018 and has since built international teams and distribution networks. Its desktop educational humanoid robots, mid-sized entertainment humanoid robots and full-size humanoid robots have all obtained international certifications, with partners now established in Southeast Asia, the Middle East and other markets.    Global expansion is also a major focus for Guangzhou-based CVTE. The company said its overseas own-brand business grew 54.83% year on year in 2025. It has established subsidiaries in 10 countries and built localized marketing and service teams across 29 countries and regions, while its products and services now reach more than 140 countries and regions worldwide. The company has also developed local production capacity in Vietnam and Mexico to strengthen the resilience and flexibility of its global supply chain.                            。网站被攻击、服务器宕机、硬盘损坏——任何一个意外都能让你的多年积累化为乌有。越来越多的站长选择用海外服务器做异地备份，但选什么样的服务器才划算？    为什么用海外服务器做备份？    相比国内云厂商的OSS或对象存储，海外VPS做备份的优势在于：数据完全自主管控、不限速跨境传输、无限扩容、多端同步。而且成本往往更低——很多海外VPS年付只要几十美元，给的硬盘还特别大。    备份服务器的核心需求    大硬盘：备份需要大量存储空间，优先选大容量HDD或大容量SSD方案    大流量：备份同步会消耗大量流量，选不限流量或高流量配额的产品    稳定性：备份服务器不需要高性能CPU，但需要稳定不掉线    低成本：备份不是生产环境，能省则省    推荐方案    入门级（个人站长/小团队） ：
日本云服务器1核2G，2M CN2带宽，月均17元。适合个人博客、小型网站的日常备份。    标准型（中小团队） ：
美国云服务器2核4G/50G SSD/5M CN2带宽，年付451元。适合中小团队日常备份Git仓库、数据库。

C |     大容量型（大量数据备份） ：
美国大硬盘VPS，E5 2650配置，8核16G，月付约570元。适合外贸图纸、产品素材、视频资料等大容量文件存储。    进阶玩法：多节点备份    真正的容灾，是数据同时存在多个地理位置。主站放美国，备份放欧洲；或者主站放香港，备份放新加坡。一个节点出问题，另一个节点立刻顶上。    一句话建议：备份服务器不需要多高的配置，但硬盘要大、流量要足、价格要低。
