Problem/Justification
The Glacier Instant Retrieval storage class (GLACIER_IR) is not a selectable option in the Cloud Sync Task for Amazon S3. This is supported with command-line rclone
Impact
Users who use the S3 Glacier Instant Retrieval class can now back up directly from TrueNAS. (Users should be aware of AWS incurred server-side costs such as per-object metadata overhead, minimum billable object size, and minimum retention times.)
