德国的法规对大多数商业文件都有明确而精确的规定，但对人事档案却没有具体规定（与税务相关的除外，见下表）。因此，对于与员工相关的信息，应遵循 GDPR，尽可能缩短个人数据的存储时间。

对于其他商业文件，包括电子邮件，适用以下税法和贸易法：
- GoBD 是一个很长的德语名称的缩写，译为 "关于妥善保存和存储电子形式的财务账簿、记录和文件以及数据访问的基本原则"。
- AO（《德国财政法典）
- HGB 或 Handelsgesetzbuch，德国商法典
这些法律将大多数商业文件分为两类：一类必须保存六年，另一类必须保存十年。下表详细列出了这 10 年和 6 年保留期的各类文件和相关电子邮件。
