Performing the initial replication
This section describes how to perform the initial backup of replication data.
NOTE:  You must be familiar with the initial backup process. For more information, see “Initial backup”.
In a replication environment, each replication DS-System must receive a copy of the initial backup data. This can be accomplished in one of two ways:
• You can allow replication to occur automatically from the production DS-System. No action is required other than importing the initial backup data. However, the backup sets will replicate the data over the WAN, which can take some time for large amounts of data.
• You can perform the initial backup to all the DS-Systems in the replication group. This requires some configuration and specific steps . However, once completed, you will be able to perform a backup immediately. Incremental forever backups can take place immediately after the initial backup has been imported to the production DS-System. However, you must wait until the initial backup has been imported to all the replication DS-Systems before sharing the DS-Clients again for replication.
To perform the initial backup to all DS-Systems in a replication group:
1. Perform an initial backup of the data to removable media that can be shipped to both the production DS-System and then to the replication DS-System(s).
NOTE:  The DS-Client account must exist on the production DS-System and all replication DS-Systems.
2. Unshare the DS-Client on all DS-Systems (production and replication). This will prevent any replication processes from being triggered for that DS-Client.
3. Run the initial backup import from the removable media to the production DS-System.
NOTE:  After this import is complete, the DS-Client can immediately perform backups of this backup set to the production DS-System.
4. Run the initial backup import from the same removable media to the replication DS-System(s).
5. Once the import is finished, share the DS-Client again for replication on all DS-Systems.
6. On the production DS-System, perform a replication check on the imported backup sets. (On the Setup menu, click DS-System Group, and then click Check Replications.)
If the initial backup was successfully imported to all DS-Systems, there will be no replication send / receive for this backup set.
