Cette rubrique explique comment gérer le cycle de vie des données Object Storage Service (OSS) à l'aide du SDK OSS pour PHP V2.
Informations générales
Toutes les données stockées dans OSS ne font pas l'objet d'accès fréquents. Toutefois, les données rarement consultées doivent être conservées pour respecter les réglementations en matière de données ou les exigences d'archivage. OSS vous permet de configurer des règles de cycle de vie qui automatisent la gestion du cycle de vie de vos données. Vous pouvez configurer deux types de règles :
Règle de cycle de vie basée sur la dernière date de modification. Ce type de règle permet de supprimer les données non modifiées depuis une longue période ou de les déplacer vers une classe de stockage plus économique adaptée aux données froides.
Règle de cycle de vie basée sur la dernière date d'accès. Ce type de règle identifie les modèles d'accès aux données et déplace automatiquement les données froides vers une classe de stockage économique. Cette approche met en œuvre un stockage hiérarchisé pour les données chaudes et froides, réduisant ainsi les coûts de stockage.
Notes
Avant de configurer une règle de cycle de vie basée sur la dernière date de modification ou la dernière date d'accès, assurez-vous de bien connaître la fonctionnalité de gestion du cycle de vie. Pour plus d'informations, consultez les rubriques Règles de cycle de vie basées sur la dernière date de modification et Règles de cycle de vie basées sur la dernière date d'accès.
L'exemple de code de cette rubrique utilise l'ID de région
cn-hangzhoude la région Chine (Hangzhou). Par défaut, le point de terminaison public est utilisé pour accéder aux ressources d'un bucket. Si vous souhaitez accéder aux ressources du bucket depuis d'autres services Alibaba Cloud situés dans la même région que le bucket, utilisez le point de terminaison interne. Pour plus d'informations sur les régions et les points de terminaison OSS, consultez la rubrique Régions et points de terminaison.Pour configurer des règles de cycle de vie, vous devez disposer de l'autorisation
oss:PutBucketLifecycle. Pour interroger les règles de cycle de vie, vous devez disposer de l'autorisationoss:GetBucketLifecycle. Pour supprimer les règles de cycle de vie, vous devez disposer de l'autorisationoss:DeleteBucketLifecycle. Pour plus d'informations, consultez la rubrique Accorder une stratégie personnalisée.
Configurer des règles de cycle de vie
Cette section fournit des exemples de code permettant de configurer des règles de cycle de vie pour un bucket, basées sur la dernière date de modification ou la dernière date d'accès. Vous pouvez modifier une ou plusieurs règles de cycle de vie configurées pour un bucket.
Configurer une règle de cycle de vie basée sur la dernière date de modification pour modifier la classe de stockage des objets avec le préfixe de nom spécifié
L'exemple de code suivant configure une règle de cycle de vie basée sur la dernière date de modification des objets afin de modifier la classe de stockage des objets dont le nom commence par le préfixe spécifié :
