Amazon Glacier
Amazon Glacier is designed to be a secure, reliable, low cost storage solution for data archiving and backup of data that is infrequently accessed, yet still important to retain for future reference. It allows users to offload the administrative burdens of operating and scaling archival storage to AWS, removing the need for hardware provisioning, data replication across multiple facilities, or hardware failure detection and repair. The service automatically replicates all data across multiple facilities and performs ongoing data integrity checks, using redundant data to perform automatic repairs if hardware failure or data corruption is discovered. Uploaded data remains stored for as long as it is needed with no additional effort from users.
