rclone is an opensource tool for syncing to various forms of cloud storage.

The 32bit ARM binary works on the reMarkable, and with just a little bit of effort it is relatively easy to sync the device with your Google drive from the ssh shell.

As of December 2020, rclone can now be installed using the Opkg (Entware) package manager. Simply SSH into your device and run:

opkg install rclone

• Download the binaries
  • Download the latest 32bit ARM binaries from https://downloads.rclone.org/rclone-current-linux-arm.zip
• Unpack the binaries

  (xenial)kimbotha@localhost:~/Downloads/src$ unzip ../rclone-current-linux-arm.zip 
  Archive:  ../rclone-current-linux-arm.zip
     creating: rclone-v1.38-linux-arm/

    inflating: rclone-v1.38-linux-arm/rclone.1  
    inflating: rclone-v1.38-linux-arm/README.txt  

• Copy the rclone binary to the reMarkable

  (xenial)kimbotha@localhost:~/Downloads/src$ cd rclone-v1.38-linux-arm/
  (xenial)kimbotha@localhost:~/Downloads/src/rclone-v1.38-linux-arm$ scp rclone root@10.11.99.1:/usr/bin/
  rclone                                                                          100%   13MB   4.4MB/s   00:03    

• SSH to the reMarkable with a port forward of 53682

  (xenial)kimbotha@localhost:~/Downloads/src/rclone-v1.38-linux-arm$ ssh -L 53682:localhost:53682 root@10.11.99.1
