If numerous small files need to be generated while analysing data, they must be generated in a temporary folder, for example on the GIGA scratch disk for cluster users, and deleted at the end of the analysis. Nevertheless, if these numerous small files need to be kept afterwards, they must be encapsulated into TAR or DAR archives and compressed before being transferred to the mass storage. Of note, the GIGA scratch disk is not backed up, and any data left there that have not been used (modified, opened or read) for a month are automatically deleted. These procedures are explained in more details in the Genomics Cluster User Charter.

If numerous small files need to be generated while analysing data, they must be generated in a temporary folder, for example on the [GIGA scratch disk](work-in-progress) for cluster users or on the computer used for the analysis, and deleted at the end of the analysis.

If needed or in case of emergency, the managers of the IT system can be contacted to discuss the situation and set up specific actions to store these data while minimising their impact on the system.

Any breach of this obligation may, in the event of abuse, end with the deletion of the data and the withdrawal of the access of the user to the GIGA's storage space. |
