I have a dataset which is quite big - a few petabytes.
Untarring it into a new filesystem takes a couple days. The problem is that the server does not allow me to have a process running over 24h - it gets killed, whether I want it or not.
This precludes me from using
screen or any other sort of process- backgrounding.
I would need to be able to resume the tar process, because it will get killed, no matter what.
