  • Under the responsability of the PI
  • Data Organization: structured project directories on NAS-DCSR.
  • Storage Rules:
    • No personal, sensitive, or admin data on NAS-DCSR and LTS.
    • Use NAS-UNIL Admin partition for Administratif personal data.
    • Use OneDrive or the NAS-UNIL Admin partition for research-related files like protocols, presentations, references, figures for paper preparation…

Short Term Storage

The DSBU, in collaboration with the Scientific Computing and Research Support Unit (DCSR), assists researchers in selecting the most appropriate storage solution for their research data at every stage of the data lifecycle. We provide guidance and support to ensure that researchers choose the best-suited platform based on the sensitivity of the data (sensitive or non-sensitive), the volume of data, and specific computing requirements. Our goal is to help you manage your data efficiently and securely, aligning with your research needs.

Long Term Storage / Archiving

Through the process of data life cycle management, our team is providing information, advice and help to FBM UNIL researchers for long term storage and preservation of their data for free at the DCSR UNIL.

Contact us for guidance on  how to prepare your Readme file and reorganize your data in order to preserve your work.

DSBU will help you by:

  1. Informing and guiding you through the process of reorganizing and describing your research data in the form of explanatory documents called “readme file”.
  2. Offering you two powerful tools, DeepScan@DSBU to screen your data folders on the NAS-DCSR and DataSquid@DSBU to generate semi-automatically the documentation as a readme file.
  3. Final validation of your readme file and data re-organization before data migration from the DCRS NAS to the LTS platform.

LTS Caracteristics

  • Under the responsability of the PI
  • Free of charge (2 copies with security and backup)
  • Time limit for storage duration (e.g. for published data at minimum 10 years after the date of the article acceptance) with possible extension (1x).
  • Restricted access (limited number of accesses to data on LTS and under request only).
  • Effective organization of your data under a project form (matched with a funding, a specific theme, a publication etc.).
  • Production of a Readme file (document describing the dataset content) for each individual futur TAR subdirectory
  • Naming rules for (TAR = Tape Archive) subdirectories in the LTS directory

Securing UNIL Data: Key Practices

  • Mandatory Storage: Store all UNIL research data on NAS Recherche DCSR or LTS (two copies required); external disk or servers are prohibited. Link: Directive UNIL 4.5 – Traitement et gestion des données de recherche )
  • Storage Rules:
    • No personal, sensitive, or admin data on NAS-DCSR and LTS.
    • Use NAS-UNIL Admin partition for Administratif personal data.
    • Use OneDrive or the NAS-UNIL Admin partition for research-related files like protocols, presentations, references, figures for paper preparation…

Procedure

Step1 – Data organization

  • You need to reorganize your data according to the projects you will have defined and clean up/eliminate obsolete data.
  • Research data must be organized into the LTS directory around a given project (matched with a funding, a specific theme, a publication etc.).

Step 2 – Transfer your data to the LTS subfolder of the NAS project

diapositive34

Two possibilities:

  • For small data: use the copy/paste function or linux command line to copy your data from D2c to LTS.
  • For big data, please contact us at dsbu@unil.ch and provide the requested information on the tab bellow. The bulk transfer will be organized through the DCSR service, as this may be required to ensure timely completion of the process.

Step 3 – TAR (Tape Archive) subdirectory to be archived

diapositive12
  • TAR archive file: size of the data volume in each individual subdirectory to be archived  is free up to 4 TB per subdirectory in the LTS directory. NDo not compress your data since this step will be done during the creation of the TAR subdirectory.
  • The TAR files to be archived must remain at the root of the LTS directory.
  • Each TAR subdirectory has to comply to naming rules (see below) and should be accompanied by an independent readme file. We require you to use our new DSBU tool DataSquid@DSBU to create a LTS Readme file that can be shortly adapted to each individual TAR subdirectory – link.
  • The naming rule only applies to the first TAR sub-folders in the LTS directory. The TAR archive files created from these directories will have the same name. Within these directories the names of the files and data directories are free.
  • Naming rules for subdirectories in the LTS directory (TAR archive file). The length of the folder name must not exceed a maximum of 40 characters according to the rules below
    • Numbers from 0-9
    • Letters a-z
    • Letters A-Z
    • Hyphen ( – ) OK but not at the beginning or end of the directory name
    • Underline ( _ ) OK but not at the beginning or end of the directory name
    • No white spaces
    • No accented characters or symbols

Step 4 – Data description (Readme file)

Complete the readme file for each distinct subdirectory to be archived in individual TAR archive file following the established guidelines.

The name and file format of the readme file for LTS must not be changed, “LongTermStorage_Data_Description_EN.txt”.

FBM Template: DSBU automated readme file

Our unit is deploying a user-friendly and automated methodology for generating readme files for FBM Datasets.

DataSquid@DSBU is an advanced tool that automates data documentation for experiments by integrating with equipment databases and laboratory protocols, ensuring comprehensive, consistent, and reproducible research documentation. link

capture d’écran 2026 08 31 à 16.08.53

Once your readme file have been approved by clebrand, they should be included at the root of each individual moved within data subdirectory and the future TAR file should be moved from the D2C directory to the LTS directory.

For any assistance feel free to contact us via our contact form, email or visit our offices: https://wp.unil.ch/dsbu/contact/

Step 5 – Procedure to request the transfer of “cold” Data to Long-term storage (tape)

Request LTS tape transfer via the NAS DCSR dashbord

  • Via the interface on the homepage, you will be able to request the LTS tape transfer for part of your data by clicking on the button “Request for long-term storage (LTS)” in the list of actions listed on the interface homepage. Connect and sign in to your NAS DCSR dashboard via your SWITCH UNIL account using this link .
  • Select «making a long term storage request» via your DCRS dashboard interface to ask for Long Term Storage (LTS).
  • To send your request for long term storage of part of your research data on magnetic tape, click on the submit button. Mention which data you would like to transfer for long term storage.
  • An e-mail will be send automatically to the DSBU. 
  • The DCSR will perform last automatic technical controls​.

Step 6 – Validation

The DCSR will create the TAR archive files and transfer your data on magnetic tape with all individual readme file included at the root of each individual TAR archive file. After completing the magnetic tape transfer process for the TAR directory, the LTS directory will include the following elements:

  • The TAR file will be renamed by adding the prefix “ARCHIVED*,” and the underlying information will only be accessible in read-only mode.
  • A copy of the readme file “LongTermStorage_Data_Description_EN.docx” will be accessible in read-only mode.
  • A file named “INVENTORY_OF_ARCHIVED_FILES.txt” within the TAR directory will list the archived files with their full paths and provide information on the recovery procedure from the tapes.

This procedure ensures that the archived data remains accessible and easily identifiable. The addition of the “ARCHIVED*” prefix allows researcher to quickly confirm that archiving has been completed by simply examining the TAR directory names at a given moment.

Step 7 – Data recovery of TAR subdirectory from magnetic tape (LTS)

Retrieval Cost Model still under discussion

  • Limited Free Retrieval Allowance: Researchers can retrieve a limited number of 5 TB of data within a 12-month period without incurring costs.
  • Additional Retrieval Cost: Retrievals exceeding the limit in the 12-month window will be charged 50 CHF per additional TB.
  • In addition to the fees associated with retrieving data from LTS tape storage, please note that the standard DCSR NAS storage costs will apply again once the data have been restored to the NAS, at approximately CHF 110 per TB per year.

Request TAR retrieval for the tape using the invoicing application available at the link below.

unknown
  • From the My Account menu, select LTS Archive and Retrieve Request.
unknown 1
  • Once on this page, select the folders you wish to retrieve and click Restore to have them restored to their original location on your NAS partition.
unknown 2

A page will then display the applicable data retrieval fees. Please note that up to 5 TB of data archived to tape within the previous 12 months can be retrieved free of charge. Any additional data retrieval will be charged at CHF 50 per TB. See the example below.

Once the data retrieval process has been completed, you will receive an email confirming that your folders have been successfully restored and providing the necessary information regarding their location and how to access them.
