Des copies de sauvegarde des espaces projet et ''home'' sont faites chaque soir; elles sont conservées pendant 30 jours et les fichiers supprimés sont conservés pendant 60 jours. Pour récupérer une version antérieure d'un fichier ou d'un répertoire, contactez le [[Technical support/fr|soutien technique]] en indiquant le chemin (''path'') complet et la date.<br />
Pour copier des données à partir de l'espace de stockage ''nearline'' vers les espaces projet, ''home'' ou ''scratch'', contactez le [[Technical support/fr|soutien technique]].

Starting April 1, 2024, new Rapid Access Service (RAS) policies will allow larger quotas for the project and nearline spaces. For more details, see the "Storage" section at [https://alliancecan.ca/en/services/advanced-research-computing/accessing-resources/rapid-access-service Rapid Access Service].  Quota changes larger than those permitted by RAS will require an application to the annual [https://alliancecan.ca/en/services/advanced-research-computing/accessing-resources/resource-allocation-competition Resource Allocation Competition (RAC)].

  1. ↑ Ce quota est fixe et ne peut être modifié.
  2. ↑ Présentement, l'espace scratch ne peut pas être augmenté et un quota supplémentaire de 100To par utilisateur s'applique temporairement sur Graham. Ce quota sera ramené à 20To quand une solution technique sera déployée.
  3. ↑ Selon la valeur de ctime pour le fichier (voir Espace scratch ː Purge automatique).
  4. ↑ L'espace projet peut être augmenté à 10To par groupe en recourant au service d'accès rapide. La demande doit être faite par le chercheur principal responsable pour le groupe en s'adressant au soutien technique.
