Summary

This article describes the Best Practices for Initial Backup of Replication Data.

Note: You must be familiar with the Initial Backup process.

New customers with large amounts of data may require the Initial Backup process. In a Replication environment, each Replication DS-System must also receive a copy of the Initial Backup data. This can be done two ways:
OPTION 1
Allow replication to occur automatically from the Production DS-System.
  • No action is required other than importing the Initial Backup data, however those backup sets will replicate the data over the WAN.
  • This can take some time for large amounts of data.
OPTION 2
Perform the Initial Backup to all the DS-Systems in the Replication Group.
  • This requires some configurations and specific steps, however once completed, the customers will be able to 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-System(s) before sharing the DS-Client(s) again for replication.

Details: Option 2 - Perform Initial Backup to all DS-Systems in a Replication Group

1. Perform a regular initial backup of the customer's data to removable media that can be shipped to both the Production DS-System and then to the Replication DS-System(s).

2. Unshare the DS-Client on all DS-Systems (Production and Replication). This will prevent any replication process 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. Any new data backed up will be replicated after step 6 (below).

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 (Setup Menu > DS-System Group > Check Replications):
