About the replication topology for Auto Image Replication
For Auto Image Replication, the disk volumes have the properties that define the replication relationships between the volumes. The knowledge of the volume properties is considered the replication topology. The following are the replication properties that a volume can have:
A source volume contains the backups of your clients. The volume is the source for the images that are replicated to a remote NetBackup domain. Each source volume in an originating domain has one or more replication partner target volumes in a target domain. | |
A target volume in the remote domain is the replication partner of a source volume in the originating domain. | |
The volume does not have a replication attribute. |
The following describes the replication topology for the supported storage types:
Table: Replication topology by storage type
Storage type | Replication topology |
|---|---|
NetBackup exposes the storage for a as a single volume. Therefore, there is always a one-to-one volume relationship for MSDP. You configure the replication relationships in the source domain. To do so, you add target storage servers in the Replication tab of the Change Storage Server dialog box of the source storage server. See the NetBackup Deduplication Guide: | |
Disk storage devices that support replication and also conform to the Veritas OpenStorage API | Your storage administrator configures the replication topology of the volumes in the storage devices. Based on the volume properties, you create homogeneous disk pools. That is, all of the volumes in a disk pool must have the same properties, and you create the disk pools to match that topology. The disk pools inherit the replication properties from the volumes that you add to them. You should work with your storage administrator to understand the topology so you can create the proper disk pools. You also should work with your storage administrator to understand any changes that are made to the replication topology. NetBackup discovers the topology of the volumes when you configure a disk pool. |
NetBackup discovers the replication topology when you configure the replication relationships. NetBackup discovers topology changes when you use the option of the Change Disk Pool dialog box.
NetBackup includes a command that can help you understand your replication topology. Use the command in the following situations:
After you configure the replication targets.
After you configure the storage server and before you configure disk pools.
After changes to the volumes that comprise the storage.
