What is an archive?
Archives and Vaults
Amazon Glacier | Storage
An archive is a durably stored block of information. You store your data in Amazon Glacier as archives. You may upload a single file as an archive, but your costs will be lower if you aggregate your data. TAR and ZIP are common formats that customers use to aggregate multiple files into a single file before uploading to Amazon Glacier. The total volume of data and number of archives you can store are unlimited. Individual Amazon Glacier archives can range in size from 1 byte to 40 terabytes. The largest archive that can be uploaded in a single Upload request is 4 gigabytes. For items larger than 100 megabytes, customers should consider using the Multipart upload capability. Archives stored in Amazon Glacier are immutable, i.e. archives can be uploaded and deleted but cannot be edited or overwritten.
How do I delete archives?
Archives and Vaults
Amazon Glacier | Storage
You can delete an archive at any time. You will stop being billed for your archive when your delete request succeeds at which point the archive itself will be inaccessible. Archives that are deleted within 3 months of being uploaded will be charged a deletion fee (see billing section for more details).
How do I upload large archives?

When uploading large archives (100MB or larger), you can use multi-part upload to achieve higher throughput and reliability. Multi-part uploads allow you to break your large archive into smaller chunks that are uploaded individually. Once all the constituent parts are successfully uploaded, they are combined into a single archive.
What is a vault?
Archives and Vaults
Amazon Glacier | Storage
A vault is a way to group archives together in Amazon Glacier. You organize your data in Amazon Glacier using vaults. Each archive is stored in a vault of your choice. You may control access to your data by setting vault-level access policies using the AWS Identity and Access Management (IAM) service. You can also attach notification policies to your vaults. These enable you or your application to be notified when data that you have requested for retrieval is ready for download.

How do I effectively manage my Amazon Glacier vaults?

Amazon Glacier allows you to tag your Glacier vaults for easier resource and cost management. Tags are labels that you can define and associate with your vaults, and using tags adds filtering capabilities to operations such as AWS cost reports. For example, you can use tags to allocate Glacier costs and usage across multiple departments in your organization or by any other categorization. You can tag your vaults by using the Glacier Console or the Glacier APIs. For more information see Tagging Your Amazon Glacier Vaults.
