The available storage areas can be
- temporary (data are cancelled after a given period) or;
- permanent (data are never cancelled or cancelled only at few months after the "end" of the project);
they can also be
- user specific (each username has a different data area) or;
- prj project specific (defined for each project - account_noaccessible by all users within the same project).
Finally the storage areas can be:
- Local: that means they are (specific for each system. );
- Shared: (the same area can be accessed by all HPC systems)
The available data areas are defined through predefined "environment variables": $HOME, $CINECA_SCRATCH, $WORK.
Important: It is the user's responsibility to backup your important data. We only guarantee a daily backup of data in the $HOME area.
$HOME: permanent/backed up, user specific, local
This is a local area where you are placed after the login procedure. It is where system and user applications store their dot-files and dot-directories (.nwchemrc, .ssh, ...) and where users keep initialization files specific for the systems (.cshrc, .profile, ...). There is a $HOME area for each username on the machine.
This area is conceived to store programs and small personal data. Files are never deleted from this area, moreover they are guaranteed by daily backups: if you delete or accidentally overwrite a file, you can ask our Help Desk (superc@cineca.it) to restore it. File retention is related to the life of the username, data are preserved until the username remains active.
$WORK: permanent, project specific, local
