# Duplicator

[English](./README.md) | 中文

NocoBase 应用的备份与还原插件，可用于应用的复制、迁移、升级等场景。

## 安装激活

内置插件无需手动安装激活。

## 使用方法

Duplicator 插件提供了 `dump` 和 `restore` 命令，分别用于备份和还原应用数据，可用于单应用的备份和还原，也可以跨应用。如果跨应用还原数据，请保证目标应用 NocoBase 版本与源应用一致，相对应插件也已下载本地。

**⚠️ 如果使用了继承（PostgreSQL）、视图、触发器等不兼容的特性，跨数据库还原备份数据可能失败。**

yarn nocobase dump
