IGB File Server Policy[edit]

In order to ensure the IGB file server is used properly and space is not wasted, we have come up with these policies. If you have any questions about any of these policies, please contact us. This page changes occasionally as we see the mission of the file server changing, so check back if you have any future questions.


CNRG will make their best effort to ensure that the file server is backed up daily. Every month full tapes from the prior month is taken off site to protect from data loss due to a disaster in the building. These tapes are then saved for a minimum of 10 years. Although we do our best to keep data backed up, if it is extremely important it is always a good idea to have a version of the file in more than one physical location (e.g., in case something unexpected happens.

Home Directory Storage Limit[edit]

Each user is allowed 50 GB of personal information in their home directory. Illegal or offensive content is not permitted as well as those file types on the banned list. This limit is a soft limit, meaning that if you go over your 50 GB of space we will send you an e-mail asking you to remedy the situation. If you wish to have a personal web page hosted by one of our servers and backed up, this is where it will be created. Personal web pages cannot cause problems with the web server or they will be disabled.

Group Directory Storage Limit[edit]

Each theme is allocated 20 TB of shared space on the server that is broken down into sub directories by faculty in the theme. The purpose of this space is to share data between faculty, students, grad students and for inter-theme communication. We will not create personal directories (those that can be accessed by only one user) in this space as that is how the home directories are to be used.

Stale Files[edit]

The file server is not intended to be a very long term storage solution for files that do not change. For instance if you have images that have not been used in 2 years we encourage you to find a longer term storage solution for the data or contact us to help you with such a search. That said, so long as the limits of your home directory or group directory have not been violated we normally will not contact you regarding this.
