mc命令 cp 和 mirror 区别
mc cp 和 mc mirror 都是 minIO Client（mc）的命令，用于在 minIO 对象存储服务中进行文件传输和同步操作。
mc cp- mc cp 用于将本地文件或对象从一个位置复制到另一个位置。
- 可以用来上传/下载文件、目录，或者在不同桶（bucket）之间进行复制。
- 通常用于单个文件或目录的复制操作。
mc mirror- mc mirror 用于在两个目录之间进行镜像同步。
- 它会递归地比较源目录和目标目录中的内容，并确保它们保持同步。
- 如果目标目录中不存在源目录中的文件，则会将其复制过去；如果源目录中的文件被删除了，则目标目录中相应的文件也会被删除。
总的来说，mc cp 主要用于简单的文件复制操作，而 mc mirror 则更适合于目录之间的完整同步操作，可以保持目录结构的一致性，并确保两个目录中的文件保持同步状态。

# MC MIRROR EXAMPLES: ###
01. Mirror a bucket recursively from MinIO cloud storage to a bucket on Amazon S3 cloud storage.
$ mc mirror play/photos/2014 s3/backup-photos
02. Mirror a local folder recursively to Amazon S3 cloud storage.
$ mc mirror backup/ s3/archive
03. Only mirror files that are newer than 7 days, 10 hours and 30 minutes to Amazon S3 cloud storage.
$ mc mirror --newer-than "7d10h30m" backup/ s3/archive
04. Mirror a bucket from aliased Amazon S3 cloud storage to a folder on Windows.
$ mc mirror s3\documents\2014\ C:\backup\2014
