AWS Glacier is a storage service with backup functionality provided by Amazon
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, see 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.
