 ## 📖 项目简介
 
-Backer 是计算机组成与体系结构/软件工程课程项目，基于 **C++17** 在 **Linux** 平台开发，使用 **CLI11** 提供命令行接口，**spdlog** 处理日志，**Google Test** 驱动测试。
+Backer 是一款 **Linux 平台的数据备份还原工具**，采用 **C++17** 开发，支持目录树备份与还原、特殊文件处理、元数据保留、灵活筛选、多格式打包、多算法压缩加密、图形界面与定时备份等完整功能。
 
-依赖通过 **CMake FetchContent** 自动拉取（CLI11 v2.4.2、spdlog v1.14.1、GTest v1.15.2），无需手动安装。加密功能依赖系统 OpenSSL（`libssl-dev`，通过 `find_package` 接入）。
+## 📁 项目结构
 
-**当前状态**：已完成核心备份/还原、特殊文件、元数据保留、自定义筛选（6 维度）、Tar/Zip 打包、gzip/zstd/lzma 压缩、AES-256-GCM/SM4-CBC 加密、Qt 6 图形界面及**定时备份（Cron 调度 + 数据淘汰）**。后续将通过管道架构扩展实时监控及网络备份等功能。

+- **基本要求**：目录树文件数据的备份与还原
+- **扩展要求**：
+  - 特殊文件支持（管道/链接/设备文件）
+  - 元数据支持（属主/时间/权限）
+  - 自定义筛选（路径/类型/名称/时间/尺寸/属主 6 维度）
+  - Tar / Zip 两种打包格式
+  - gzip / zstd / lzma 三种压缩算法
+  - AES-256-GCM / SM4-CBC 两种加密算法
+  - Qt 6 图形界面
+  - cron 定时备份与自动淘汰

+要点：
+- 自底向上五层分层架构：(1)存储层（本地文件系统）→ (2)基础设施层（FSAbstraction/元数据管理/特殊文件支持）→ (3)管道层（Filter→Packer→Compressor→Encryptor）→ (4)业务层（BackupEngine/RestoreEngine/Scheduler）→ (5)表现层（CLI + GUI），各层间箭头标注数据流向。右侧标注关键技术：CLI11、spdlog、Qt6、OpenSSL、miniz、ccronexpr
+- 采用**五层分层架构** + **管道模式**设计
+  - 表现层：CLI (CLI11) + GUI (Qt 6)
+  - 业务层：BackupEngine / RestoreEngine / BackupScheduler
+  - 管道层：Filter → Packer → Compressor → Encryptor 可插拔组合
+  - 基础设施层：FSAbstraction / Metadata / 特殊文件处理
+  - 存储层：LocalStorage
+- 各层通过抽象接口通信，上层依赖下层，下层对上层无感知
+- ![五层分层架构](diagrams/dist/backer-layers.svg)
+---
+
+---
+标题：核心模块 — 备份/还原引擎
+要点：
+- **BackupEngine**: 备份流程编排器
+  - `walk(source)` → 遍历目录树获取 FileEntry 列表
+  - `filter(entries)` → 按 6 维度筛选
+  - `pack(entries)` → Tar/Zip 打包
+  - `compress(buffer)` → gzip/zstd/lzma 压缩
+  - `encrypt(buffer)` → AES/SM4 加密
+  - `storage.write()` → 持久化到本地
+- **RestoreEngine**: 还原流程编排器（逆操作）
+  - 支持目录镜像模式（逐个文件复制）和归档模式（打包文件）
+- 备份流程完整步骤：用户输入 backup 命令 → CLI 解析参数 → BackupEngine 调起 → FSAbstraction 遍历目录 → Filter 筛选 → Packer 打包 → Compressor 压缩 → Encryptor 加密 → Storage 写入磁盘，各步骤可选（虚线框标注）
+---
+
+---
+标题：核心模块 — 管道策略接口
+要点：
+- 采用**策略模式**设计管道阶段，新增算法无需修改现有代码
+- **Filter**：`apply(entries)` → 返回筛选后子集
+- **Packer**：`pack/unpack(files, fs, stream)` → TarPacker / ZipPacker
+- **Compressor**：`compress/decompress(input, output)` → Gzip / Zstd / Lzma
+- **Encryptor**：`encrypt/decrypt(input, output, password)` → AES-256-GCM / SM4-CBC
+- 使用工厂模式 (`CompressorFactory` / `EncryptorFactory`) 实现算法注册与按名创建
+- 所有接口使用 `std::expected<T, ErrorCode>` 返回，错误传播清晰
+---
+
+---
+title: UML 建模 — 用例图
+要点：
+- 主要用例包括：备份数据（含筛选文件子用例）、还原数据、管理定时任务（含添加/删除/启用/禁用子用例）、查看备份索引、配置参数（含选择打包格式/选择压缩算法/选择加密算法子用例）
+- 覆盖全部需求功能点

+- ![UML 用例图](diagrams/dist/backer-use-case.svg)
+---
+
+---
+标题：UML 建模 — 类图
+要点：
+- 五大分层核心类：表现层（MainWindow/BackupTab/CLICommands）、业务层（BackupEngine/RestoreEngine/BackupScheduler）、管道层（Filter←CriteriaFilter, Packer←TarPacker/ZipPacker, Compressor←GzipCompressor/ZstdCompressor/LzmaCompressor, Encryptor←OpenSslEncryptor）、基础设施层（FSAbstraction←LocalFsAbstraction）、存储层（Storage←LocalStorage）
+- 管道层全部采用接口（纯虚类）设计，支持可插拔策略
+- 表现层与业务层解耦，CLI 和 GUI 共用同一套业务接口
+- ![UML 类图](diagrams/dist/backer-class.svg)
+---
+
+---
+标题：UML 建模 — 顺序图 / 构件图
+要点：
+- 一次完整备份请求的交互流程：用户→CLI→BackupEngine→FSAbstraction(walk)→Filter(apply)→Packer(pack)→Compressor(compress)→Encryptor(encrypt, PBKDF2+AES)→Storage(writeFile)→返回结果
+- 可执行构件（backer-cli/backer-gui/backer_test）与各编译单元（commands.cpp, backup_engine.cpp, tar_packer.cpp 等）及外部依赖（CLI11/spdlog/Qt6/OpenSSL/miniz/ccronexpr/Google Test）之间的链接和依赖关系
+- 顺序图清晰展示备份请求在 5 层架构中的完整传递路径
+- 构件图反映编译期依赖关系，指导模块化开发和增量编译

+  - 每个功能独立分支开发，PR 合入前需 CI 通过 + Code Review
+- **Git 提交规范**：`<type>(<scope>): <description>` 格式
+  - 如 `feat(core):` / `fix(cli):` / `docs(usage):` / `perf(ci):`
+- **版本发布**：git tag + GitHub Release 自动发布
+  - 当前版本：`release/airprofly_01-v1.0.0`
+- **问题追踪**：GitHub Issues（bug report 模板 + 任务分配）
+---
+
+---
+标题：项目亮点与难点
+要点：
+- **亮点**：
+  - 可插拔管道架构：新增压缩/加密算法仅需 3 个文件（接口实现+工厂注册）
+  - 跨平台三平台（Linux/macOS/Windows）CI 持续验证
+  - 依赖零系统化：`git clone` → `cmake --build` 即可产出可执行软件
+  - Full pipeline 串联：打包+压缩+加密可同时启用

+## 课程背景 
+本课程是电子科技大学计算机专业学生的最后一门实践类必修课程，旨在让学生在本科学习的最后阶段能对所学知识进行综合运用和融会贯通。
+
+课程围绕一个模拟实战的软件项目，让学生以团队为单位，完成从需求分析、系统设计、程序编码到集成测试的整个软件生命周期。
+
+通过对软件工程的全流程实践，提升学生的系统分析与建模能力、程序设计与实现能力、团队协作及领导能力，使学生具备足够的面向市场和科研环境的工程能力和职业素养。 
+
+
+对软件开发过程、软件开发方法、软件开发环境有所掌握并进行基本实践。
+
+设计并实现一款数据备份软件，以项目组形式推进，每组最多三人。
+
+基于面向对象的软件工程方法学进行项目推进，经历从需求分析、系统设计、编码实现、软件测试的整个软件生命周期。
+
+实验最终成果包括一款基本可用的软件及其对应文档。
+
+软件应包括选定的完整功能，重点考察其正确性、易用性、健壮性。
+
+软件文档应包括：需求分析说明书、系统设计文档、软件测试报告，重点考察其规范性、一致性、可读性。
+
+采用现代化软件开发工具辅助项目开发，包括但不限于：项目管理工具（Teambition），UML建模工具（StarUML），集成开发环境（VSCode、make、gdb），版本控制工具（git），代码检测工具（cpplint），软件测试工具（gtest、valgrind、gprof、perf）。
