    Amazon Glacier is a storage solution for "cold data."

    Amazon Glacier is an extremely low-cost storage service that
    provides secure, durable and easy-to-use storage for data backup
    and archival. With Amazon Glacier, customers can store their data
    cost effectively for months, years, or decades. Amazon Glacier
    also enables customers to offload the administrative burdens of
    operating and scaling storage to AWS, so they don't have to worry
    about capacity planning, hardware provisioning, data replication,
    hardware failure and recovery, or time-consuming hardware
    migrations.

    Amazon Glacier is a great storage choice when low storage cost is
    paramount, your data is rarely retrieved, and retrieval latency of
    several hours is acceptable. If your application requires fast or
    frequent access to your data, consider using Amazon S3. For more
    information, go to `Amazon Simple Storage Service (Amazon S3)`_.

    You can store any kind of data in any format. There is no maximum
    limit on the total amount of data you can store in Amazon Glacier.

    If you are a first-time user of Amazon Glacier, we recommend that
    you begin by reading the following sections in the Amazon Glacier
    Developer Guide :

    + `What is Amazon Glacier`_ - This section of the Developer Guide
      describes the underlying data model, the operations it supports,
      and the AWS SDKs that you can use to interact with the service.
    + `Getting Started with Amazon Glacier`_ - The Getting Started
      section walks you through the process of creating a vault,
      uploading archives, creating jobs to download archives, retrieving
      the job output, and deleting archives.

        This operation lists jobs for a vault, including jobs that are

        Amazon Glacier retains recently completed jobs for a period
        before deleting them; however, it eventually removes completed
        jobs. The output of completed jobs can be retrieved. Retaining
        completed jobs for a period of time after they have completed
        enables you to get a job output in the event you miss the job
        completion notification or your first attempt to download it

        to download an archive. After the job completes, you start to
        download the archive but encounter a network error. In this
        scenario, you can retry and download the archive while the job
        exists.

        To retrieve an archive or retrieve a vault inventory from
        Amazon Glacier, you first initiate a job, and after the job
        completes, you download the data. For an archive retrieval,
        the output is the archive data, and for an inventory
        retrieval, it is the inventory list. The List Job operation
        returns a list of these jobs sorted by job initiation time.

        This List Jobs operation supports pagination. By default, this
        operation returns up to 1,000 jobs in the response. You should
        always check the response for a `marker` at which to continue
        the list; if there are no more items the `marker` is `null`.
        To return a list of jobs that begins at a specific job, set
        the `marker` request parameter to the value you obtained from
        a previous List Jobs request. You can also limit the number of
        jobs returned in the response by specifying the `limit`
        parameter in the request.

        Additionally, you can filter the jobs list returned by
        specifying an optional `statuscode` (InProgress, Succeeded, or
        Failed) and `completed` (true, false) parameter. The
        `statuscode` allows you to specify that only jobs that match a
        specified status are returned. The `completed` parameter
        allows you to specify that only jobs in a specific completion
        state are returned.

        This operation initiates a job of the specified type. In this
        release, you can initiate a job to retrieve either an archive
        or a vault inventory (a list of archives in a vault).

        Retrieving data from Amazon Glacier is a two-step process:

        #. Initiate a retrieval job.
        #. After the job completes, download the bytes.

        The retrieval request is executed asynchronously. When you
        initiate a retrieval job, Amazon Glacier creates a job and
        returns a job ID in the response. When Amazon Glacier
        completes the job, you can get the job output (archive or
        inventory data). For information about getting job output, see
        GetJobOutput operation.

        The job must complete before you can get its output. To
        determine when a job is complete, you have the following
        options:

        + **Use Amazon SNS Notification** You can specify an Amazon
          Simple Notification Service (Amazon SNS) topic to which Amazon
          Glacier can post a notification after the job is completed.
          You can specify an SNS topic per job request. The notification
          is sent only after Amazon Glacier completes the job. In
          addition to specifying an SNS topic per job request, you can
          configure vault notifications for a vault so that job
          notifications are always sent. For more information, see
          SetVaultNotifications.
        + **Get job details** You can make a DescribeJob request to
          obtain job status information while a job is in progress.
          However, it is more efficient to use an Amazon SNS
          notification to determine when a job is complete.

        The information you get via notification is same that you get
        by calling DescribeJob.

        If for a specific event, you add both the notification
        configuration on the vault and also specify an SNS topic in
        your initiate job request, Amazon Glacier sends both
        notifications. For more information, see
        SetVaultNotifications.

        An AWS account has full permission to perform all operations
        (actions). However, AWS Identity and Access Management (IAM)
        users don't have any permissions by default. You must grant
        them explicit permission to perform specific actions. For more
        information, see `Access Control Using AWS Identity and Access
        Management (IAM)`_.

        **About the Vault Inventory**

        Amazon Glacier prepares an inventory for each vault
        periodically, every 24 hours. When you initiate a job for a
        vault inventory, Amazon Glacier returns the last inventory for
        the vault. The inventory data you get might be up to a day or
        two days old. Also, the initiate inventory job might take some
        time to complete before you can download the vault inventory.
        So you do not want to retrieve a vault inventory for each
        vault operation. However, in some scenarios, you might find
        the vault inventory useful. For example, when you upload an
        archive, you can provide an archive description but not an
        archive name. Amazon Glacier provides you a unique archive ID,
        an opaque string of characters. So, you might maintain your
        own database that maps archive names to their corresponding
        Amazon Glacier assigned archive IDs. You might find the vault
        inventory useful in the event you need to reconcile
        information in your database with the actual vault inventory.

        **About Ranged Archive Retrieval**

        You can initiate an archive retrieval for the whole archive or
        a range of the archive. In the case of ranged archive
        retrieval, you specify a byte range to return or the whole
        archive. The range specified must be megabyte (MB) aligned,
        that is the range start value must be divisible by 1 MB and
        range end value plus 1 must be divisible by 1 MB or equal the
        end of the archive. If the ranged archive retrieval is not
        megabyte aligned, this operation returns a 400 response.
        Furthermore, to ensure you get checksum values for data you
        download using Get Job Output API, the range must be tree hash
        aligned.

        An AWS account has full permission to perform all operations
        (actions). However, AWS Identity and Access Management (IAM)
        users don't have any permissions by default. You must grant
        them explicit permission to perform specific actions. For more
        information, see `Access Control Using AWS Identity and Access
        Management (IAM)`_.

        when you initiated the job, the output will be either the
        content of an archive or a vault inventory.

        A job ID will not expire for at least 24 hours after Amazon
        Glacier completes the job. That is, you can download the job
        output within the 24 hours period after Amazon Glacier
        completes the job.

        If the job output is large, then you can use the `Range`
        request header to retrieve a portion of the output. This
        allows you to download the entire output in smaller chunks of
        bytes. For example, suppose you have 1 GB of job output you
        want to download and you decide to download 128 MB chunks of
        data at a time, which is a total of eight Get Job Output
        requests. You use the following process to download the job
        output:

        #. Download a 128 MB chunk of output by specifying the
           appropriate byte range using the `Range` header.
        #. Along with the data, the response includes a checksum of
           the payload. You compute the checksum of the payload on the
           client and compare it with the checksum you received in the
           response to ensure you received all the expected data.
        #. Repeat steps 1 and 2 for all the eight 128 MB chunks of
           output data, each time specifying the appropriate byte range.
        #. After downloading all the parts of the job output, you have
           a list of eight checksum values. Compute the tree hash of
           these values to find the checksum of the entire output. Using
           the Describe Job API, obtain job information of the job that
           provided you the output. The response includes the checksum of
           the entire archive stored in Amazon Glacier. You compare this
           value with the checksum you computed to ensure you have
           downloaded the entire archive content with no errors.

        of the entire archive you have uploaded. For information about
        computing a SHA256 tree hash, see `Computing Checksums`_. On
        the server side, Amazon Glacier also constructs the SHA256
        tree hash of the assembled archive. If the values match,
        Amazon Glacier saves the archive to the vault; otherwise, it
        returns an error, and the operation fails. The ListParts
        operation returns a list of parts uploaded for a specific
        multipart upload. It includes checksum information for each
        uploaded part that can be used to debug a bad checksum issue.

        Additionally, Amazon Glacier also checks for any missing
        content ranges when assembling the archive, if missing content
        ranges are found, Amazon Glacier returns an error and the
        operation fails.

        Complete Multipart Upload is an idempotent operation. After
        your first successful complete multipart upload, if you call
        the operation again within a short period, the operation will
        succeed and return the same archive ID. This is useful in the
        event you experience a network issue that causes an aborted
        connection or receive a 500 server error, in which case you
        can repeat your Complete Multipart Upload request and get the
        same archive ID without creating duplicate archives. Note,
        however, that after the multipart upload completes, you cannot
        call the List Parts operation and the multipart upload will
        not appear in List Multipart Uploads response, even if
        idempotent complete is possible.

        Amazon Glacier rejects your upload part request if any of the
        following conditions is true:

        + **SHA256 tree hash does not match**To ensure that part data
          is not corrupted in transmission, you compute a SHA256 tree
          hash of the part and include it in your request. Upon
          receiving the part data, Amazon Glacier also computes a SHA256
          tree hash. If these hash values don't match, the operation
          fails. For information about computing a SHA256 tree hash, see
          `Computing Checksums`_.
        + **Part size does not match**The size of each part except the
          last must match the size specified in the corresponding
          InitiateMultipartUpload request. The size of the last part
          must be the same size as, or smaller than, the specified size.
          If you upload a part whose size is smaller than the part size
          you specified in your initiate multipart upload request and
          that part is not the last part, then the upload part request
          will succeed. However, the subsequent Complete Multipart
          Upload request will fail.
        + **Range does not align**The byte range value in the request
          does not align with the part size specified in the
          corresponding initiate request. For example, if you specify a
          part size of 4194304 bytes (4 MB), then 0 to 4194303 bytes (4
          MB - 1) and 4194304 (4 MB) to 8388607 (8 MB - 1) are valid
          part ranges. However, if you set a range value of 2 MB to 6
          MB, the range does not align with the part size and the upload
          will fail.

        This operation is idempotent. If you upload the same part
        multiple times, the data included in the most recent request
        overwrites the previously uploaded data.
