Failed to import backup Backup TISO-FS-1 2023 #2 Details: REST API error: 'S3 error: The operation is not valid for the object's storage class

Hello,

As we can see from the error message, it seems that the object you are trying to access resides in Glacier storage class. Please note to perform any operation on an object that resides in Glacier storage class, you need to first restore the object. Refer the below document.

[+] Restoring an archived object - https://docs.aws.amazon.com/AmazonS3/latest/userguide/restoring-objects.html [+] https://repost.aws/knowledge-center/s3-batch-operation-initiate-restore

Further, you mentioned that you have disabled the lifecycle rule now but objects that are already transitioned to Glacier storage class will still reside in Glacier class itself.

That being said, if you would like further look into this issue, we require details that are non-public information. Please open a support case with AWS using the following link and share S3 request ID pair for the request where you are witnessing the error "The operation is not valid for the object's storage class".
