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)].

↑ L'espace scratch peut être augmenté à 100To par utilisateur sur demande; écrivez au soutien technique.
↑ L'espace projet peut être augmenté à 10To par groupe sur demande; écrivez au soutien technique. Les requêtes en provenance de membres d'un même groupe seront additionnées sans excéder 10To.

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