About restoring data from Amazon Glacier vault
The NetBackup image is stored as a set of data archives in the GLACIER_VAULT storage class. Restore from Amazon Glacier vault happens in two phases.
The archives are first retrieved at an internal staging location that is maintained by Amazon.
From there, the data is restored to the destination location.
The staging restore operation takes a minimum of 3 hours to 5 hours. The archives are available at the Amazon staging location for a maximum of 24 hours.
Note:
NetBackup supports Amazon Standard retrievals that complete within a minimum of 3 hours to 5 hours. When you perform a restore, the entire image fragment is brought to the staging location while only the selected archives are downloaded.
If the files and folders you want to restore belong to multiple image fragments, consider the following:
One image fragment is retrieved at a time. Only after the selected files and folders part of the first image fragment are downloaded, the next image fragment is retrieved.
The restore time must be considered depending on the number of image fragments. For example, if the files you want to restore are part of two fragments, an additional 6 - 10 hours are added to the complete restore time.
Note:
If you cancel a job after the restore retrieval is initiated, cost is incurred for all the objects that are retrieved on the staging location till the point of cancellation.
