Before tearing down any JH cluster at the end of term, need to make sure and make a backup copy of all the course JH home folders to Box.  Below is how to use rclone to copy the data to Box.

First will need to download the Linux binary of rclone from [[https://rclone.org/downloads/|here]]

Copy the rclone zip file to the course hub you want to copy the user home folders by login into your own JH session from the Canvas course page link.  Unpack the rclone zip file and move the rclone binary to /home/.hub_local/bin/.

Then run
  rclone config
  
Select Box from the list and type the default settings through. When it asks "Use web browser to automatically authenticate rclone with remote?" choose no. And run the command it shows on  your own system with rclone installed and has a web browser to grant the access.  This will then display the token on your system. Copy that token to the JH command line.  Then save the rclone config and exit the config.  

Next you will need to login to the nfs server for the class hub.  From the controller server switch to the course JH hub

  k ns {class_hub_name}
  k get pods

This from the list of pods you will want to login to the nfs server nfs-bds311x001homedrive-dep-0 for example.
To login to the pod run

  k exec -it nfs-bds311x001homedrive-dep-0 -- bash

Then do:
  cd /nfsshare
  tar cvf home.tar *
  mv home.tar {your_home_folder}/.
  cd {your_home_folder}
  chown {your_UID} home.tar
  exit

Then back in your JH session in terminal app run the following rclone command to copy the file to Box
  rclone copy --progress home.tar  box:UIT\ -\ Institutional\ Root/Technical\ \&\ Solutions\ Architecture/DRI\-EPM/DRI/restores/dsosu/Winter2024/BDS311/

Of course on Box, be sure to have that folder already created.
