45) How long will it take to restore my objects archived in S3 Glacier and can I upgrade an in-progress request to a faster restore speed?
When processing a retrieval job, Amazon S3 first retrieves the requested data from S3 Glacier, and then creates a temporary copy of the requested data in S3 (which typically takes a few minutes). The access time of your request depends on the retrieval option you choose: Expedited, Standard, or Bulk retrievals. For all but the largest objects (250MB+), data accessed using Expedited retrievals are typically made available within 1-5 minutes. Objects retrieved using Standard retrievals typically complete between 3-5 hours. Bulk retrievals typically complete within 5-12 hours.
