AWS 宕机时,你不会

你的基础设施运行在多个云上。当一个故障时,其他的自动接管。

问题所在

单云就是单点故障

2024 年关键云故障事件同比增长 18%,持续时间延长 18.7%,其中 68% 由人为错误导致。当你唯一的云宕机时,一切都宕机了。你的客户、你的收入、你的声誉——全部沦为他人基础设施的人质。

工作原理

一条命令,始终在线。

1

复制

运行 rdc replicate production --target secondary。增量同步——仅传输变更的块。

2

监控

持续健康检查即时检测故障。可连接到您的监控栈(Grafana、Prometheus)。

3

故障转移

流量在 30 秒内切换到健康的基础设施。自动 DNS 更新。零手动步骤。

底层技术

为什么跨云复制既快又便宜

Rediacc 使用 btrfs send/receive 在文件系统层面计算增量差异。不是传输完整镜像,只有变更的数据块在站点之间移动。一个 380 GB 的环境如果每天有 2.4 GB 的变更,就只传输 2.4 GB——而非 380 GB。这意味着 98% 的带宽节省。复制可以持续运行或按计划执行。

重要意义

您将获得什么

始终在线

一个云失败,另一个接管。无需手动干预。健康检查失败时自动触发故障转移。可连接到您的监控栈。

默认多云

AWS、Azure、GCP、Hetzner 或您自己的硬件。混合搭配。任何带 btrfs 的 Linux 机器都可以作为复制目标。

无供应商锁定

Move between clouds whenever you want. Open-format snapshots. No proprietary agents. Standard btrfs — available in every modern Linux kernel.

差距对比

没有其他工具能在数秒内完成跨云故障转移

云原生工具在其云内复制。备份工具在数小时后恢复。Rediacc 跨任何提供商复制,并在 30 秒内故障转移。
