The quota settings for these two folders are as follows. The quota settings for these two folders are as follows.
#### /home/ #### /home
In `/home/<user>`, each user has a (hard) quota of 10GB. This directory should be used only for configuration files (e.g. RC files) and data that should remain permanently on that server (e.g., [Python Virtual Environments](/virtualenv)). In `/home/<user>`, each user has a (hard) quota of 10GB. This directory should be used only for configuration files (e.g. RC files) and data that should remain permanently on that server (e.g., [Python Virtual Environments](/virtualenv)).
#### /space/ #### /space
In `/space/<user>` each user has a (soft) quota of 100GB and a (hard) quota of 5T with a grace period of 7 days. This means that users will be able to occupy a large disk space (more than half of the total 8TB available), but only for short periods of time (less than 7 days). After that, the user will not be able to write to disk anymore until he frees all space exceeding 100GB.

This is intended to allow all users to have a large temporary storage (e.g., to accomodate a large input dataset), but at the same time forbid them from keeping a large portion of the (limited) total space for themselves for a long time.

#### IMPORTANT: Automatic Data Removal from /space/ #### IMPORTANT: Automatic Data Removal from /space
Importantly, a script running on icaro will **automatically remove** all data in `/space/<user>` 7 days after the user's last login to that server. So: Importantly, a script running on icaro will **automatically remove** all data in `/space/<user>` 7 days after the user's last login to that server. So:
- You should always remember to login periodically if you have long jobs running - You should always remember to login periodically if you have long jobs running
