Utilizzare InitiateJob con un SDK AWS o una CLI

Recupera un archivio da una vault. Questo esempio utilizza la classe ArchiveTransferManager. Per informazioni dettagliate sull’API, consulta ArchiveTransferManager.

Il comando seguente avvia un processo per ottenere un inventario del vault my-vault.

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

Output:

{
    "location": "/0123456789012/vaults/my-vault/jobs/zbxcm3Z_3z5UkoroF7SuZKrxgGoDc3RloGduS7Eg-RO47Yc6FxsdGBgf_Q2DK5Ejh18CnTS5XW4_XqlNHS61dsO4CnMW",

}

Amazon Glacier richiede un argomento ID account durante l’esecuzione delle operazioni, ma puoi utilizzare un trattino per specificare l’account in uso.

Il comando seguente avvia un processo per recuperare un archivio dal vault my-vault.

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

job-archive-retrieval.json è un file JSON nella cartella locale che specifica il tipo di processo, l’ID di archivio e alcuni parametri facoltativi:

{
  "Type": "archive-retrieval",
  "ArchiveId": "kKB7ymWJVpPSwhGP6ycSOAekp9ZYe_--zM_mw6k76ZFGEIWQX-ybtRDvc2VkPSDtfKmQrj0IRQLSGsNuDp-AJVlu2ccmDSyDUmZwKbwbpAdGATGDiB3hHO0bjbGehXTcApVud_wyDw",
  "Description": "Retrieve archive on 2015-07-17",
  "SNSTopic": "arn:aws:sns:us-west-2:0123456789012:my-topic"
}

Gli ID di archivio sono disponibili nell’output di aws glacier upload-archive e aws glacier get-job-output.

Output:

{
    "location": "/011685312445/vaults/mwunderl/jobs/l7IL5-EkXyEY9Ws95fClzIbk2O5uLYaFdAYOi-azsX_Z8V6NH4yERHzars8wTKYQMX6nBDI9cMNHzyZJO59-8N9aHWav",
    "jobId": "l7IL5-EkXy2O5uLYaFdAYOiEY9Ws95fClzIbk-azsX_Z8V6NH4yERHzars8wTKYQMX6nBDI9cMNHzyZJO59-8N9aHWav"
}

Per informazioni sul formato dei parametri del processo, consulta la sezione relativa alla richiesta di avvio del processo nella documentazione di riferimento dell’API Amazon Glacier.

Esempio 1: avvia un processo per recuperare un archivio dal vault specificato di proprietà dell’utente. Lo stato del processo può essere verificato utilizzando il cmdlet Get-GLCJob. Quando il processo viene completato correttamente, è possibile utilizzare il cmdlet Read-GCJobOutput per recuperare il contenuto dell’archivio nel file system locale.

Start-GLCJob -VaultName myvault -JobType "archive-retrieval" -JobDescription "archive retrieval" -ArchiveId "o9O9j...TX-TpIhQJw"

Output:

JobId            JobOutputPath Location
