+## [Quotas](mass-storage/mass-storage-quota)
+
+Storage space is finite and expensive. For this reason, space allocated to each laboratory is limited by a quota. Once the quota of a folder is reached, users stop being able to write in it. If this happen while saving files, it may lead to data corruption and lost of data. Some tools will give a warning or an error message but other won't. **It's the user's responsibility to make sure there is enough space to write in the folder.**
+
+Each user's personal home folder is limited to **100 Gb**. 
+
+There are also quotas for the Platforms and Research Units folders. 
+
+More details about quotas can be found [here](mass-storage/mass-storage-quota).

 ## 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.

 # 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).
