Disk space

/home

When logging in to any of our servers you will automatically land in your "home" directory.

Everything that is small and important, like scripts and programs, should be under you your home!!! Because your home is backed up every 3 hours. You find more information about the backup  and how to retrieve it if need be under:  home backup

Everything else should go under your "data space" - see below.

Everybody who has an account on our internal servers has a home directory, which is the same(!) on all our internal servers. It is called:

    /home/username

When logging in you will automatically land in your home directory. If you are in another directory and would like to go back into your home directory you can do that with a simple:

    cd

    '~' is another way to address a synonym for your home directory. For example:  cd ~

    '~username' is a synonym to address for the home directory of user 'username'. For example:  cd ~username

Home quota

You can put up to 500 MB of data under your home. There is no limit for the number of files. You can check your current quota with the command:
     quota
For more information about the command see: quota

If you prefer to have your scripts and programs with your data, you can create with symbolic links from the places from which you want to access them to the place under your home where they really are. You can find a short info about the link command, 'ln', here : Link files

Data space

Since most users will have more than 500 GB of data the home is too small to store all of them. Therefore, every user also has one or more "data spaces" assigned to their account. You find the name of your (first) data space in the email you got about your account creation.

You Under your data space you can put here , for example: model output, input and output of your scripts and programs, etc.

No general backup is done for the data under the data space. However, there is a possibility to have up to 1 TB of selected directories backed up once a week. Have a look at the following page to learn more: Data backup

There are no quotas for the data space. The data space is shared by everybody using the same filesystem (main base directory). So before putting more than ~5 TB on any filesystem, make sure there is enough space free! You can check the usage of any mounted filesystem with the command 'df'. For example:
    df -h /filesystem
If you see the usage of a filesystem is greater than 95% let me (winger.katja@uqam.ca) know, please!!!
