Restoring from Amazon Glacier vault spans more than 24 hours for single fragment
Archives stored in Amazon Glacier vault, once retrieved, are available for download for only 24 hours. If your NetBackup restore job (for images residing in Amazon Glacier vault) takes more than 24 hours to download a single fragment, the restore job may fail while reading the image. For example, if your fragment size is 512 GB and restore speed is less than 50 Mbps, the restore will fail.
To recover from this situation, do one of the following:
Use a checkpoint restore.
Start a restore for the remaining files.
Duplicate the image with lesser fragment size.
