Rclone

Rclone is a command-line program that synchronizes files and directories between different cloud storage services, including Google Drive, Amazon S3, Microsoft OneDrive, Dropbox, and more. With its flexible configuration options and robust feature set, Rclone provides a powerful tool for managing and accessing data stored in the cloud.

Configuration

Mounting remote filesystem, in this example via SFTP. The remote profile is called myremote, and authentication is done with user myuser and key file /root/.ssh/id_rsa against 192.0.2.2. The remote directory /my_data is than mounted to the local directory /mnt.

environment.systemPackages = [ pkgs.rclone ];
environment.etc."rclone-mnt.conf".text = ''
  [myremote]
  type = sftp
  host = 192.0.2.2
  user = myuser
  key_file = /root/.ssh/id_rsa
'';

fileSystems."/mnt" = {
  device = "myremote:/my_data";
  fsType = "rclone";
  options = [
    "nodev"
    "nofail"
    "allow_other"
    "args2env"
    "config=/etc/rclone-mnt.conf"
  ];
};
