BRANCH OFFICE CONSOLIDATION WITH THE DELL POWERVAULT DL2000 –
POWERED BY COMMVAULT SIMPANA REPLICATION
A typical Remote Office Backup solution is shown in the illustration. Software is
deployed on a MediaAgent located at a remote office, and a MediaAgent located
at the centralized data center. Thus, there is no impact on end users and client
computers, since all operations involve MediaAgents only. Deployment and
configuration occur once, and the solution continues to function without any
further operator intervention. Once the initial transfer of data has been
completed at the time of deployment, all data replication after that point will
involve only data that has changed on the MediaAgent, similar in concept to
Incremental Backups. This is different from an Auxiliary Copy operation, which is
similar in concept to Full Backups, copying all selected data every time it runs, and
also expanding all Single Instanced data each time.
