自托管 · PostgreSQL · age 加密

SupaCove 用 pg_dump 导出托管 PostgreSQL 的数据，流式加密后备份到你自己的 S3 兼容对象存储。失败明确可见，恢复独立于实例。

快速开始 GitHub 先看怎么恢复

Aiven、Prisma Postgres、TigerData、Miget、Render 按标准 PostgreSQL 接入，尚未逐一实测

免费套餐
补上自动备份
为 Supabase、Neon、Railway 的免费套餐按 Cron 计划自动备份，旧备份按保留策略清理。
怎么备份 Supabase 数据库 →
付费套餐
多一份第三方备份
在平台自带的备份之外，再留一份加密副本在你自己的对象存储里。

01功能

每个功能，都有一页文档。

age 加密，私钥在你手里

X25519 + ChaCha20-Poly1305；实例默认只保存公钥（recipient），私钥由你离线保管

~~仅手动~~→0 3 * * *

Cron 计划与新鲜度阈值

标准五段或 @daily 别名，IANA 时区；超过阈值未成功即 EXPIRED

重试 130s
重试 260s
重试 3120s
重试 4240s

Webhook 通知，至少一次

三种事件经 outbox 投递，退避重试，耗尽后标记 dead

心跳监控

成功且新鲜的备份 ping 一次，失败 ping /fail；超时未 ping 由外部监控告警

托管或自托管，一套流程

Supabase、Neon、Railway 有专门的连接提示；Aiven、Prisma Postgres、TigerData、Miget、Render 按“自托管/其他”注册

SB_VERIFY_ENABLED

内嵌恢复验证

每次成功备份后在内嵌 PostgreSQL 里恢复一次；默认关闭，开启需向实例提供私钥文件

02加密

私钥只出现一次，由你离线保管。

备份在导出的同时用 age 流式加密。默认情况下实例内只保存公钥，解密用的私钥由你离线保管。

内置 age 算法库X25519 + ChaCha20-Poly1305，无需外部 age CLI
实例默认只存公钥实例内只保存公钥（recipient）。唯一的例外是开启恢复验证：那需要把私钥文件交给运行中的实例
丢失私钥 = 备份不可恢复identity.txt 是解密所有备份的唯一私钥，请离线加密保存

03快速开始

三条命令，跑起一台实例。

构建镜像、启动容器、领取一次性令牌。接着初始化 age 身份、注册数据库并做首次备份，最后验证一次恢复。

按六步走完快速开始 →

06验证恢复

04流水线

一次备份，六个阶段。

导出、加密、提交任何一步失败，任务都会落为 failed。验证和通知各有自己的状态：验证失败不改写任务结果，通知重试耗尽会标记 dead。

05保证

四条保证，不打折扣。

01
失败不伪装成功
导出、加密、提交任何一步失败，任务都会落为 failed，绝不会标记 succeeded。
02
重启可收敛
停机中断的任务记为 interrupted，不产生假失败告警。满足续传条件时启动自动续传；不满足时保持可解释的终态，由下一次计划运行恢复备份链。
03
备份独立可恢复
恢复只需要三样东西：密文文件、离线保存的 age 私钥、恢复套件脚本。
04
秘密不出错误面

06常见问题

先回答，再细说。

Supabase 免费套餐有备份吗？: Supabase 官方文档写明免费套餐的项目没有自动备份，并建议定期导出数据、保留异地副本。SupaCove 按 Cron 计划替你做这件事。Supabase 官方文档 · 核对于 2026-10-08
和平台自带的备份有什么区别？: 平台的备份留在平台里。SupaCove 的副本在写出前就已加密，存进你自己的对象存储，私钥由你离线保管，恢复时不需要这台实例。
备份包含 Supabase Storage 里的文件吗？: 不包含。备份是对 Postgres 数据库的一次完整 pg_dump：包含 auth 用户记录和 storage 对象元数据，不包含文件内容、Edge Functions 代码和项目设置。
恢复需要什么？: 密文及其 manifest、离线保存的 age 私钥、恢复套件脚本，以及一个空的 PostgreSQL 数据库。Supabase 的备份要恢复到带有 Supabase 扩展的服务器上，步骤见 Supabase 指南。
支持哪些平台？: Supabase、Neon、Railway 有专门的连接提示。Aiven、Prisma Postgres、TigerData、Miget、Render 是标准 PostgreSQL，按“自托管/其他”注册，我们尚未逐一实测。CockroachDB 不支持。

先恢复一次，再相信备份。

快速开始一共六步，最后一步就是用恢复套件把刚做的备份恢复到一个新库里。强烈建议做一次。
