# Important rules
|
|
|
|
|
|
|
|
## Terms of use
|
|
|
|
|
|
|
|
As the GIGA mass storage has been designed to store scientific data, the following types of data **can't** be stored on it:
|
|
|
|
|
|
|
|
* personal data
|
|
|
|
|
|
|
|
* professional data not related to the function carried out for the University of Liège and/or CHU
|
|
|
|
|
|
|
|
* copyrighted material for which the user doesn't have the rights
|
|
|
|
|
|
|
|
* files that can decrease the stability of the system or increase its vulnerability
|
|
|
|
|
|
|
|
You'll find more information on the mass storage usage rules [here](mass-storage/mass-storage-term-use)
|

|
|
## Good practices
|
|
|
|
|
|
|
|
- **Don't keep several copies of files**
|
|
|
|
|
|
|
|
All files present in your home or project folders on the mass storage are backed up on a tape library situated at the SEGI (B26). This means that there are two copies of all your files in two different buildings. So there is no need to keep several copies of your files. If a file that has been backed up is deleted by mistake, we can retrieve it for 28 days, and in some cases, we can even retrieve a previous version of your file, for example if you modified it by mistake (less than 28 days ago, at the condition that there hasn't been more than 25 different versions of the file since then). You'll find more information about backing up policies [here](mass-storage/mass-storage-backup-archive) . Moreover, the mass storage is a professional material and thus much more stable than external drives.
|
|
|
|
|
|
|
|
- **Use compression tools when possible and group numerous small files in DAR archives**
|
|
|
|
|
|
|
|
- **Keep all the files associated to a project in that project folder and not in your home**
|
|
|
|
|
|
|
|
This will allow all people working on a given project to access these data and work on them. It will also facilitate the upload of the data to public database when submitting a publication.
|
|
|
|
|
|
|
|
- **Name files and directories according to the mandatory rules described below**
|
|
|
|
|
|
|
|
You'll find more recommendations on data management and file naming [here](mass-storage/mass-storage-management-practices).

|
|
|
## Mandatory rules for file and folder names
|
|
|
|
|
|
|
|
File and folder names can only contain the following characters:
|
|
|
|
|
|
|
|
* digits 0 to 9
|
|
|
|
* lowercase letters a to z
|
|
|
|
* uppercase letter A to Z
|
|
|
|
* underscore and/or hyphen
|
|
|
|
|
|
|
|
They must **never** contain:
|
|
|
|
|
|
|
|
* spaces, tabulations or punctuation other than hyphen (-) and underscore (_)
|
|
|
|
* Japanese, Chinese, Korean, Greek, Hebraic, Arabic or other non-English characters and ideograms
|
|
|
|
* Diacritics such as accent, umlaut, tilde or cedilla (é, è, ê, ä, á, í, ñ, õ, ç, etc.)
|
|
|
|
* special characters such as , ; . : ! ? / \ “ # [ ] > < % * = & $ | ^ ( ) { }
|
|
|
|
* system reserved keywords such as CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9
|
|
|
|
|
|
|
|
Overall, try to give files and directories short, meaningful and easily understandable names so that anybody working on the same project can easily find them.

# Connection to the mass storage
|
|
|
|
|
|
|
|
For a detailed description of the different methods you can use to connect to the mass storage, see [here](mass-storage/mass-storage-connection).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
# Once logged in to the mass storage
|
|
|
|
|
|
|
|
Once logged in to the mass storage, you'll be in a folder called your "home". This home folder is accessible only to you. It is organised with a \_SHARE_ folder containing links to all the shared project folders you have access to as well as to some shared resources. A complete view of the tree can be found [here](work-in-progress).
|
|
|
|
|
|
|
|
Beside this \_SHARE_ folder, a user's home directory can also contain folders and files the user doesn't need to share with anybody.
