一、Rclone 简介[1]
Rclone是一个命令行程序，用于管理云存储上的文件。它是云供应商web存储界面的一个功能丰富的替代品。超过40种云存储产品支持rclone，包括S3对象存储、业务和消费者文件存储服务以及标准传输协议。
RCONE具有与unix命令rsync、cp、mv、mount、ls、ncdu、tree、rm和cat相当的强大云功能。Rclone熟悉的语法包括shell管道支持和--dry-run 保护。它在命令行、脚本中或通过其API使用。
用户称rclone为“云存储的瑞士军刀”，以及“与魔法无法区分的技术”。
Rclone真的很关心你的数据。它始终保留时间戳并验证校验和。有限带宽上的传输；从上次传输的良好文件开始，可以重新启动间歇性连接或受配额限制的连接。您可以检查文件的完整性。在可能的情况下，rclone采用服务器端传输，以大限度地减少本地带宽使用，并在不使用本地磁盘的情况下从一个提供商传输到另一个提供商。
虚拟后端包装本地和云文件系统，以应用加密、压缩、分块、散列和连接。
Rclone将任何本地、云或虚拟文件系统作为磁盘安装在Windows、macOS、linux和FreeBSD上，并通过SFTP、HTTP、WebDAV、FTP和DLNA提供服务。
Rclone是一款成熟的开源软件，初的灵感来自rsync，是用Go编写的。友好的支持社区熟悉各种用例。官方Ubuntu、Debian、Fedora、Brew和巧克力回购。包括一个。对于新版本，建议从http://rclone.org下载。
Rclone广泛应用于Linux、Windows和Mac上。第三方开发人员使用rclone命令行或API创建创新的备份、恢复、GUI和业务流程解决方案。
Rclone承担着与云存储通信的重任。
、Rclone同步工具常用用法参考
三、Rclone SSH/SFTP方式挂载Linux目录
经常使用Linux服务器的同学，有时候可能会用到数据同步的，常用的rsync，scp等。现在不妨可以体验一上rclone。
生成ssh公钥密钥
ssh-keygen -q -t rsa -b 4096 -C "rclone key" -N "" -f ~/.ssh/rclone
cd ~/.ssh/
cat rclone* > rclone-merged # <- 须做项，否则会连接失败在服务器server中添加pub key到~/.ssh/authorized_keys
ssh-copy-id -i ~/.ssh/rclone.pub root@192.168.32.33rclone配置
