UC Berkeley JupyterHubs
No non-hidden files in the user’s home directory have been modified in
the last 12 months.
Zip the whole home directory
Upload it to Google drive of a
created for this purpose
Share the ZIP file in the Google Drive with the user.
Today (6 Feb 2020), we have 18,623 home directories in datahub. Most of
these users used datahub in previous semesters, have not logged in
for a long time, and will probably never log in again. This costs us
a lot of money in disk space - we will have to forever expand disk space.
By cleaning it up after 12 months of non-usage, we will not affect any
current users - just folks who haven’t logged in for a long time. Archiving
the contents would make sure people still have access to their old work,
without leaving the burden of maintaining it forever on us.
For UC Berkeley users, Google Drive offers Unlimited Free Space.
We can also perform access control easily with Google Drive.
Email it to our users. This will most likely be rejected by most
mail servers as the home directory will be too big an attachment
Put it in Google Cloud Nearline storage,
build a token based access control mechanism on top, and email this
link to the users. We will need to probably clean this up every 18 months
or so for cost reasons. This is the viable alternative, if we decide to
not use Google Drive
