Git基础知识** Git是一个分布式版本控制系统,它允许开发人员跟踪代码更改并协作工作。它使用快照机制来存储代码历史记录,每个快照称为一个提交。每个提交都包含代码的副本以及有关更改的信息,例如作者、日期和提交消息。 Git仓库是存储代码历史记录的中央存储库。它包含所有提交以及指向每个提交的引用。当开发人员对代码进行更改时,他们会创建一个新的提交,该提交将添加到仓库中。这使开发人员可以轻松地回滚更改、查看代码历史记录以及协作工作。 # 2. Git数据恢复理论 ### 2.1 Git版本控制原理 Git是一种分布式版本控制系统(DVCS),它允许开发人员跟踪代码库中文件的更改。Git使用快照系统来存储代码库的状态,每个快照称为提交(commit)。每个提交都包含代码库中所有文件的完整副本,以及提交者信息、提交时间戳和提交消息。 ### 2.2 数据恢复机制 Git的数据恢复机制基于其版本控制原理。当文件从代码库中删除时,Git不会立即删除该文件。相反,它将该文件标记为已删除,并将其存储在Git历史记录中。这意味着即使文件已从工作目录中删除,但仍然可以在Git历史记录中找到它。 ### 2.3 常见数据丢失场景 有几种常见的数据丢失场景,其中Git可以帮助恢复数据: - **本地文件删除:**当开发人员从工作目录中删除文件时,但尚未提交更改。 - **远程文件删除:**当开发人员从远程代码库中删除文件时,但尚未将更改推送到本地代码库。 - **提交历史记录丢失:**当开发人员意
