Restoring data from Amazon Glacier
NetBackup image is stored as set of objects with specified storage class, in this case, Glacier storage class. Restore from Amazon Glacier happens in two phases. The objects are first retrieved at an internal staging location that is maintained by Amazon and from there the data are restored at the destination location. The entire restore operation takes minimum 3 - 5 hours. The objects are available at the Amazon staging location depending on the retrieval retention period you have specified. Veritas recommends that you set the retrieval retention period to minimum 3 days. After the retrieval retention period expires, the data is transitioned back to Amazon Glacier.
NetBackup supports Amazon Standard retrievals, which complete within minimum 3 - 5 hours.
When you perform a restore, the entire image fragment is restored while only the selected objects are downloaded.
The following diagram illustrates the high-level restore process.
If the files and folders, you want to restore belong to multiple image fragment 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, the additional 6hrs - 10 hrs will be added to the complete restore time.
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.
