二 |     S Korea-Vietnam-economic tiesS. Korea, Vietnam vow stronger ties in cutting-edge sectors, building on FTA SEOUL, Aug. 26 (Yonhap) -- South Korea and Vietnam vowed to further bolster economic exchanges with the goal of increasing bilateral trade to US$150 billion by 2030 and strengthening supply chain cooperation, Seoul's industry ministry said Wednesday. The two countries made the pledge during meetings of their joint industrial cooperation free trade agreement committees in Seoul, according to the Ministry of Trade, Industry and Resources. During the meetings, Industry Minister Kim Jung-kwan and his Vietnamese counterpart, Le Manh Hung, discussed ways to achieve the 2030 target and vowed to make progress in quarantine negotiations on Vietnamese lychees and passion fruit and South Korean tangerines and kiwifruit. Bilateral trade between South Korea and Vietnam was estimated at $94.6 billion in 2025, with the volume reaching $62.4 billion over the January-June period this year.                   This illustration depicts trade with Vietnam. (Yonhap)The two countries agreed to address challenges faced by South Korean firms operating in Vietnam while accelerating technology exchanges. Vietnam vowed to work closely with its local governments to help South Korean businesses secure local workers, while South Korea agreed to help its firms share advanced technologies with Vietnamese partners. South Korea and Vietnam will seek to ensure the smooth launch of a critical minerals supply chain technology center. The two countries vowed to continue talks on expanding cooperation across the critical minerals supply chain to ensure stable supplies for South Korean firms operating in Vietnam. The ministry said the two countries additionally agreed to pursue long-term cooperation in the energy sector, including the joint stockpiling of crude oil and the establishment of an emergency response mechanism. During the meetings, Korea National Oil Corp. and PetroVietnam Oil Stockpile Ltd. signed a memorandum of understanding to build an oil storage facility in Vietnam. The ministry said the project is expected to lay the foundation for stable oil supply chain cooperation between the two countries and across the Asia-Pacific region. "Since the FTA with Vietnam took effect, bilateral trade has grown by an annual average of 10 percent," Kim said in his opening remarks, raising expectations that the figure could reach $100 billion this year. "We will seek to expand the scope of trade and investment in a future-oriented manner, as Vietnam seeks to move beyond merely attracting investment toward adopting cutting-edge technologies, upgrading local production capabilities and pursuing green and digital transitions," Kim added.

三 | 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。

四 |     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。

五 |     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。花小钱买安心，这笔账怎么算都不亏。
