Disk space, memory and CPU power
Your home
On all of our internal servers you have the same home called: /HOME/username
For your home you have a quota of 500 MByte.
Everything under the home directories is backed up. You can find more information about our backup policies and how to retrieve the backups on the following wiki: Home backup
Since the homes are backed up it is highly recommended to keep everything that is small and important under your home, like all your scripts and programs! You can work with symbolic links if you like to have your scripts and programs accessible from other directories or on other file systems. You can find a short info about the links command here : Link files
Your data
To store your data you have disk space available on a filesystem on one of our internal servers. You find the names in the email you got about your account creation.

You can check the available memory with the command: free You can check and monitor the usage of your own processes with the command 'top'. For example: top -u ${USER} # You can use the command as is. The variable 'USER' is defined by default and set to your username. Once 'top' opened press the key 'M' (capital) to sort the processes according to memory usage instead of CPU usage. Look the the column 'RES'. |
