It is important to be aware that backup and restore operations to the cloud involve two stages. BRMS manages one stage of the operation and the other stage is controlled by the IBM Cloud Storage Solutions for i product.

The backup process
The first stage of a cloud backup is a BRMS backup to internal tape or virtual optical images. These require resources on the backup system that can be intensive and does consume space. The second stage is the transfer of the virtual images to the cloud.
...
The transfer operations to the cloud are not owned by the BRMS component. The cloud connection, transfer operations, and transfer performance is managed by the IBM Cloud Storage Solutions for i product. Additionally, any journal receiver maintenance needed for the IBM Cloud Storage Solutions for i product has to be handled separately since this journaling is not part of a BRMS owned process.

WarningLarge backup virtual images can cause lengthy transfer times when the images are moved and may degrade network performance. |
...
Because BRMS performs the backup to local media or media images, the backup system requires at least as much storage space as the size of the backup. When using virtual optical images to store a backup, significantly more storage space may be required.

When using cloud turnkey control groups as your primary backup strategy for multiple systems, BRMS recommends setting unique volume prefixes. Reference BRMS Networking with IBM Cloud Storage Solutions for i for more details. |
