À utiliser InitiateJob avec un AWS SDK ou CLI

Récupérez une archive dans un coffre. Cet exemple utilise la ArchiveTransferManager classe. Pour API plus de détails, voir ArchiveTransferManager.

La commande suivante lance une tâche visant à obtenir un inventaire du coffre my-vault :

aws glacier initiate-job --account-id - --vault-name my-vault --job-parameters '{"Type": "inventory-retrieval"}'

Amazon Glacier nécessite un argument d’ID de compte pour effectuer des opérations, mais vous pouvez utiliser un trait d’union pour spécifier le compte en cours d’utilisation.

La commande suivante lance une tâche visant à récupérer une archive depuis le coffre my-vault :

aws glacier initiate-job --account-id - --vault-name my-vault --job-parameters file://job-archive-retrieval.json

job-archive-retrieval.jsonest un JSON fichier du dossier local qui indique le type de tâche, l'ID de l'archive et certains paramètres facultatifs :

  "Type": "archive-retrieval",
  "ArchiveId": "kKB7ymWJVpPSwhGP6ycSOAekp9ZYe_--zM_mw6k76ZFGEIWQX-ybtRDvc2VkPSDtfKmQrj0IRQLSGsNuDp-AJVlu2ccmDSyDUmZwKbwbpAdGATGDiB3hHO0bjbGehXTcApVud_wyDw",
