Explanation: An archive is a durably stored block of information. You store your data in Amazon Glacier asarchives. You may upload a single file as an archive, but your costs will be lower if you aggregate yourdata. TAR and ZIP are common formats that customers use to aggregate multiple files into a singlefile before uploading to Amazon Glacier. The total volume of data and number of archives you can store are unlimited. Individual AmazonGlacier 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 largerthan 100 megabytes, customers should consider using the Multipart upload capability. Archivesstored in Amazon Glacier are immutable, i.e. archives can be uploaded and deleted but cannot be edited or overwritten.
