S3 Glacier

Storage

Amazon S3 Glacier is a low-cost, long-term cloud storage service designed for data archiving, backup and disaster recovery, and compliance requirements. S3 Glacier provides secure and durable storage for infrequently accessed data at a lower cost compared to Amazon S3 standard storage. Data retrieval times can range from minutes to several hours, making S3 Glacier an ideal solution for storing large amounts of data that are infrequently accessed.

Costs

The cost of using S3 Glacier depends on the amount of storage space used, the data retrieval speed, the number of requests, and the data transfer. The cost of data retrieval and transfer can vary based on the amount of data involved and the region in which the data is stored.

Direct Cost

$ per GB - <Region> data transfer to <Region>

name = "glacier-sns-topic"
}

resource "aws_glacier_vault" "my_archive" {
name = "MyArchive"

notification {
sns_topic = aws_sns_topic.aws_sns_topic.arn
events = ["ArchiveRetrievalCompleted", "InventoryRetrievalCompleted"]
}

access_policy = <<EOF
