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
in-progress and jobs that have recently finished.
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
fails. For example, suppose you start an archive retrieval job
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

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.

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.

"""
This operation initiates a multipart upload. Amazon Glacier
creates a multipart upload resource and returns its ID in the
response. The multipart upload ID is used in subsequent
requests to upload parts of an archive (see
UploadMultipartPart).
When you initiate a multipart upload, you specify the part
size in number of bytes. The part size must be a megabyte
(1024 KB) multiplied by a power of 2-for example, 1048576 (1
MB), 2097152 (2 MB), 4194304 (4 MB), 8388608 (8 MB), and so
on. The minimum allowable part size is 1 MB, and the maximum
is 4 GB.
Every part you upload to this resource (see
UploadMultipartPart), except the last one, must have the same
size. The last one can be the same size or smaller. For
example, suppose you want to upload a 16.2 MB file. If you
initiate the multipart upload with a part size of 4 MB, you
will upload four parts of 4 MB each and one part of 0.2 MB.
You don't need to know the size of the archive when you start
a multipart upload because Amazon Glacier does not require you
to specify the overall archive size.
After you complete the multipart upload, Amazon Glacier
removes the multipart upload resource referenced by the ID.
Amazon Glacier also removes the multipart upload resource if
you cancel the multipart upload or it may be removed if there
is no activity for a period of 24 hours.

You call this operation to inform Amazon Glacier that all the
archive parts have been uploaded and that Amazon Glacier can
now assemble the archive from the uploaded parts. After
assembling and saving the archive to the vault, Amazon Glacier
returns the URI path of the newly created archive resource.
Using the URI path, you can then access the archive. After you
upload an archive, you should save the archive ID returned to
retrieve the archive at a later point. You can also get the
vault inventory to obtain a list of archive IDs in a vault.
For more information, see InitiateJob.
In the request, you must include the computed SHA256 tree hash
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.

multiple times, the data included in the most recent request
overwrites the previously uploaded data.
