There are multiple methods for restoring data from Amazon S3 Glacier Flexible Retrieval or Amazon S3 Glacier Deep Archive. The default operation of the Cloud Storage Archive Recall workflow is to initiate a restore from S3 Glacier using multiple s3:RestoreObject requests for backup or archival data. Commvault recommends using faster restores from Amazon S3 Glacier, which leverages Amazon S3 Batch Operations to perform restores from S3 Glacier faster and at reduced cost.
