Buffer オブジェクトの 1 メガバイトのチャンクのマルチパートアップロードを作成します。
// Create a new service object and some supporting variables
var glacier = new AWS.Glacier({ apiVersion: "2012-06-01" }),
vaultName = "YOUR_VAULT_NAME",

numPartsLeft = Math.ceil(buffer.length / partSize),
startTime = new Date(),
params = { vaultName: vaultName, partSize: partSize.toString() };
// Compute the complete SHA-256 tree hash so we can pass it
// to completeMultipartUpload request at the end
var treeHash = glacier.computeChecksums(buffer).treeHash;
// Initiate the multipart upload
console.log("Initiating upload to", vaultName);
// Call Glacier to initiate the upload.
glacier.initiateMultipartUpload(params, function (mpErr, multipart) {
if (mpErr) {
console.log("Error!", mpErr.stack);
return;
}
console.log("Got upload ID", multipart.uploadId);
// Grab each partSize chunk and upload it as a part
for (var i = 0; i < buffer.length; i += partSize) {
var end = Math.min(i + partSize, buffer.length),

};
// Send a single part

glacier.uploadMultipartPart(partParams, function (multiErr, mData) {
