In all configurations, there are clients that need to be backed up, a server that manages these backups, a server that writes to and reads from backup targets, and the backup targets themselves. In some environments, the backup management and read/write functions are performed on a single server. Networking connectivity can be via Ethernet LAN or Fibre Channel SAN.

, encompassing these networked devices. The NetWorker Clients generate the backup data, while a NetWorker Server manages the backup traffic. Specifically, the NetWorker Server supports the backup and stores tracking and configuration information. NetWorker Storage Nodes write data to and read data from backup targets. Anot er way to e ne a NetWor er ata zone s to say t at t s t e set o osts manage y a single NetWorker server. This includes all hosts with backup devices controlled by the NetWorker server and all hosts who send their backup data to those devices. NetWorker clients may be backed up by multiple NetWorker servers and therefore may belong to multiple data zones. NetWorker servers and storage nodes may belong to only one data zone. In large NetWorker environments, storage nodes serve as an aggregation point for a large number o c ents.

. The full range of systems that might require their data to be backed up can include LAN clients, Windows and UNIX Servers, databases and VMWare servers. The backup traffic gets routed through the servers that write to storage – in this example, a Tape Library. In this case, tapes are rotated out of the tape library and are shipped via trucks to an offsite location. The tapes are stored so the data can be recovered in case of a disaster at the . The metadata associated with the backup is stored with the backup server managing the environment. The metadata is instrumental to the backup system’s ability to quickly locate and restore data.

With tape library storage systems, data is sometimes stored on staging disks called the primary disk pool. It is then migrated to the physical tape library or primary tape pool. The . , three copies of the data must be tracked in some situations: primary tape pool, and the copy tape pool.

also act as the primary target for backups for clients located at the secondary site. By implementing Data Domain systems, the tape library configuration becomes optional. Company policies or the need for regulatory compliance both determine the degree to which tapes can be entirely or partially replaced at a site. Some sites may also choose to use Data Domain replication to partially or completely eliminate the transportation of tapes by truck for vaulting.

The Backup software addresses the usable space exactly as it would a standard file system mount point such as NTFS, JFS, UFS, and so forth. In a VTL or SAN environment, typically, prior investments have usually been in tape – either physical or virtual. Administrators who know how to manage, monitor, and configure SAN environments can adopt the Data Domain system as a Virtual Tape Library more easily. Data Domain systems can run in a mixed mode capacity, providing both interface methods concurrently to one or many servers. This flexibility affords a great number of integration scenarios.

The NetWorker AFTDs accept concurrent streams, writing them into separate files in the directory structure of the AFTD. For VTL implementations, use the NetWorker Device Manager drivers to interface with the VTL Library changer with little policy change.

. To successfully integrate the Data Domain system into a backup environment, first perform the basic installation and configuration tasks shown in the diagram. In the first step, make certain that all installations have occurred, including installation of all application software as necessary throughout the environment, and installation and initial configuration of the Data Domain system for proper network access by client systems and backup . Steps two and three are typically performed by Implementation Engineers. In the second step, configure the Data Domain system with the correct networking, and create a backup user. Third, configure the backup server with the necessary credentials or other settings as necessary, and create a share on the Data Domain system.

DD Boost provides the advantages of improved throughput, backup server managed file replication and backup server replica awareness. How is this possible and why is this important in a backup, recovery and archive environment?


24

'

.

How does DD Boost improve throughput?

Improved throughput of “retaining” data (backups) is accomplished with the Open Storage Technology (0ST) protocol and the Data Domain Distributed Segment Processing (DSP). OST when compared with CIFS and NFS protocols has a faster throughput. Distributed Segment Processing offloads art of the Dedu lication rocess to the Backu Server if enabled to further im rove performance.


25

Without DD Boost, replication is initiated and managed by the Data Domain system. The Backup server is not aware of the data written on the replica Data Domain system (B). With DD Boost, the Backup server can now initiate and manage file replication.


26

Because DD Boost allows for the Backup server to be aware of the replica Data Domain system, it can directly restore and recover from the replica Data Domain system. Prior to DD Boost, the backup server could not control or manage the replica data. This made restoring the data from a replica a manual process.

, that administrators see them as a single solution. Working entirely from the NetWorker console, administrators can create all backup routines, set up cloning tasks, and determine which pieces of data to send from site to site, without the need to go to multiple places to see that backups and replication have completed successfully. As a result, management time for data protection is reduced significantly.

so on, so that none of the clients sending save sets need to wait for the other clients to finish. The interleaving of save sets has a significant impact on deduplication efficiency when the Data Domain device is used as a virtual tape library (VTL). Multiplexed streams hinder the deduplication process from efficiently identifying blocks of common data because of the additional header information added to the data with parallelism. In order to realize the full benefit of deduplication, EMC recommends multiplexing be turned off when using the Data Domain appliance as a VTL with NetWorker by setting both target sessions and max sessions on each virtual tape drive to a value of 1. Note that the use of parallelism is not an issue if the Data Domain system is used as a NAS target by creating an Advanced File Type Device (AFTD) on CIFS or NFS shares because each save set is stored as a separate file regardless of parallelism settings. The older File Type Device (FTD) stores save sets as multiplexed however, and is affected.
