Amazon Glacier is a cloud-based storage service that is optimized for data archiving and backup. It is designed for storing data that is infrequently accessed and has a long retention period. When data is stored in Amazon Glacier, it is stored in archives. An archive is a collection of one or more files that are grouped together into a single unit.
Amazon Glacier provides three retrieval options for archives:
Standard retrieval: This is the default option for retrieving archives. It typically takes 3-5 hours to retrieve an archive using this option.
Bulk retrieval: This option is designed for retrieving large amounts of data. It can take several hours to retrieve an archive using this option.
Expedited retrieval: This option is designed for retrieving archives quickly. Archives can be retrieved in as little as 1-5 minutes using this option.
Given the requirement that the data must be delivered within 5 minutes of a retrieval request, the best retrieval option to choose is Expedited retrieval (Option B).
Vault Lock (Option A) is a feature that allows you to lock down your Amazon Glacier vault with a policy that cannot be modified or deleted. This can help to prevent data loss or tampering.
Bulk retrieval (Option C) is a retrieval option that is designed for retrieving large amounts of data. It can take several hours to retrieve an archive using this option.
Standard retrieval (Option D) is the default option for retrieving archives. It typically takes 3-5 hours to retrieve an archive using this option.
