S3 Glacier Deep Archive

As explained in Amazon Web Services in Action, Third Edition: An in-depth guide to AWS

S3 Glacier Deep Archive is an Amazon S3 storage class optimized for the lowest-cost long-term archival storage, with retrieval typically taking hours.

S3 Glacier Deep Archive is an Amazon S3 storage class for long-term archival at the lowest listed storage cost. In US East (N. Virginia), storage is shown as $0.00099 per GB-month, but retrieval is very expensive and can take up to 48 hours. section 7.4

Use Deep Archive when the data is retained for a long time and rarely accessed:

  • Archive documents or other objects that may be needed only a few times over several years. section 7.4
  • Enable Block Public Access on buckets, especially those containing sensitive archived information. section 7.9

Restoring an archived document

An archived tax statement cannot be copied directly to a local directory. Submit a restore request for the object, inspect its metadata while restoration is ongoing, and copy it only after the restore completes. The restored copy remains available until its stated expiry date.
