About Amazon S3 storage classes
NetBackup supports storage classes for Amazon S3 and Amazon GovCloud. While you configure a cloud storage, you can select a specific storage class that you want to assign to your objects or your data backups. The objects are stored according to their storage classes.
NetBackup supports the following Amazon S3 storage classes:
(IA stands for Infrequent Access.)
Select the (Infrequent Access) storage class to restore less frequently accessed data with single zone resiliency.
Images that are written to Glacier using MSDP direct cloud tiering can be read only by a restore operation. The import, verify, or duplicate operations cannot read the images.
NetBackup cannot write images to the MSDP direct cloud tiering Glacier storage server when it is configured as AIR target storage server.
(Not supported by MSDP direct cloud tiering)
Images that are written to Glacier Deep Archive using MSDP direct cloud tiering can be read only by a restore operation. The import, verify, or duplicate operations cannot read the images.
(Not supported by MSDP direct cloud tiering)
For more about Amazon S3 storage classes, review Amazon S3 Storage Classes.
In the following scenarios, NetBackup assigns the default STANDARD storage class to the backups or objects:
If you do not select a specific storage class while you configure the Amazon S3 cloud storage
If the backups were configured in an earlier NetBackup version
Note:
If you initiate a restore from Glacier or Glacier Deep Archive, NetBackup initiates a warming step. NetBackup does not proceed with the restore until all the data is available in S3 storage to be read.
The warming step is always done if using Amazon. For storage classes other than Glacier and Glacier Deep Archive, the warming step is almost immediate with no meaningful delay. For Glacier and Glacier Deep Archive, the warming step may be immediate if files were previously warmed and are still in S3 Standard storage. However, it may take several minutes, hours, or days depending on settings being used.
