以下命令将名为 archive.zip 的当前文件夹中的存档上传到名为 my-vault 的文件库：

aws glacier upload-archive --account-id - --vault-name my-vault --body archive.zip

输出：

{
    "archiveId": "kKB7ymWJVpPSwhGP6ycSOAekp9ZYe_--zM_mw6k76ZFGEIWQX-ybtRDvc2VkPSDtfKmQrj0IRQLSGsNuDp-AJVlu2ccmDSyDUmZwKbwbpAdGATGDiB3hHO0bjbGehXTcApVud_wyDw",
    "checksum": "969fb39823836d81f0cc028195fcdbcbbe76cdde932d4646fa7de5f21e18aa67",

}

Amazon Glacier 在执行操作时需要一个账户 ID 参数，但您可以使用连字符来指定正在使用的账户。

要检索上传的存档，可使用 aws glacier initiate-job 命令启动检索任务。

上传档案。

// Load the SDK for JavaScript
import { UploadArchiveCommand } from "@aws-sdk/client-glacier";

示例 1：将单个文件上传到指定的文件库，返回档案 ID 和计算出的校验和。

Write-GLCArchive -VaultName myvault -FilePath c:\temp\blue.bin

输出：

示例 2：将文件夹层次结构的内容上传到用户账户中的指定文件库。对于上传的每个文件，cmdlet 都会发出文件名、相应的档案 ID 和计算出的存档校验和。

Write-GLCArchive -VaultName myvault -FolderPath . -Recurse

输出：
