-pre-stage files when they are unused for 2 weeks
-purge files when fs occupation reaches 95%.
-do not purge file whose name matches ".local/*"
and so on...
There is a lot of possibilities with:
-events. When doing a check?
ie: fs occupations reaches N%, ...
-filters. Which object is concerned?
ie: file attributes (path, name, size, age, user, ...)
-actions. What to do with them?
ie: copy in, copy out, purge, ...
