software solution that works with a wide selection of disk storage devices, physical tape libraries and even Cloud services. The latest edition (V 9.0) also supports client-side deduplication as a licensable feature.

This mode requires the configuration of a respective local user on the CommVault media server and configuration changes to the CommVault services. Individual users can then be assigned access to individual shares on the D2D Backup System. This - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 7

2. Now that the D2D Backup System is a member of the domain its shares can be managed from any computer on the domain by configuring a customized Microsoft Management Console (MMC) with the Shared Folders snap-in. To do this first open a new MMC window by typing mmc at the command prompt or from the - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 11
4. Click Add > and in the dialog box choose Another computer to be managed and select Shares from the View options. 5. Click Finish and OK to complete the snap-in set up. Configuring AD Authentication Mode 11 - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 12
Note that the Folder Path field contains an internal path on the D2D Backup System. 6. Save this customized snap-in for future use. 12 Configure the D2D CIFS server - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 13

NOTE: In some cases, when switching the D2D Backup System from No Authentication or User Authentication mode to AD mode, it may be necessary to log out and back into a Windows client before it is possible to access the D2D shares.

could configure User Authentication and add additional CommVault-based user names to the Share Access Permissions, but this is only recommended if the D2D Backup System is not in an AD domain. 2. On the master screen click the control panel icon and select EZ Operations. On the EZ operations menu - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 15

5. Go to the Storage Device - Deduplication tab and uncheck Enable Deduplication because all the deduplication is going to take place on the D2D NAS share. Click OK. NOTE: Alternatively you can use the EZ Operations wizard to set up a backup job as we did to configure the backup target previously. - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 25

4. Windows Explorer also shows the types of files created. CommVault creates a folder per mount path such as V_32. The example shows the backup to CommVaultShare1 has been split into 4GB containers (called CHUNKS by CommVault) as we set in our Storage Policy.

involves data overwrites which in turn generates housekeeping. If a housekeeping blackout window is set, this should limit the impact of the data aging process. If a housekeeping blackout window is NOT set, schedule the data aging process to run outside of the backup windows as shown below: 32 Other - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 33

. D2D housekeeping configuration It is a standard best practice with HP D2D Backup Systems to schedule housekeeping (space reclamation) to occur outside of backup windows to ensure there is no I/O contention on the device and ensure maximum backup performance. To set the Windows when housekeeping - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 35
to get the best deduplication ratio from a D2D device type HP recommend that similar data types be directed to the same device (VTL or NAS Share). This approach can tend to go against the CommVault Simpana automated storage management techniques and may require some manual configuration overrides - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 36
The screen shot below shows how to create a replica Disk Library for use in this type of scenario. In addition mount paths can be configured for data load balancing.

based Disk Library configuration will have only one mount path, i.e. the share used to create it in the first place. Therefore, this setting is only relevant if multiple network share paths are created during the setup of the Disk Library. • Fill and spill mount paths: This specifies that the system - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 38
of the major benefits of HP D2D Backup Systems with StoreOnce deduplication is the ability to replicate the data stored over low bandwidth links to another D2D Backup System on a Disaster Recovery site. Here we will briefly show how replication for D2D NAS shares is configured. See the next chapter - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 39
4. Click Add Target Appliance. The target is accessed and placed online for the source device. Click Next. 5. No target shares are created so we will create a new target share (from the source D2D Backup System). Enter details and click Create New Target Share. 6. The target share is created and - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 40
the target in a process known as "seeding" - this is a one-off process where the current total contents of the source are transferred to the target. Subsequent backups to CommVaultShare1 will result in only unique changed data being replicated to the target D2D Backup System. 40 D2D NAS replication - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 41

Both D2D Backup Systems and Media Agents are configured as a CommVault replica disk library, with the primary path (read/write - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 43
D2D Backup System: • BackupShare - To be used as the mount point for the replica disk library • CommcellDR - To be used for the Commcell DR backup During normal operation, the Media Agent at Site A writes backup data to the replica disk library D2D-A, which is subsequently replicated to D2D-B via - HP D2D | D2D NAS Integration with CommVault (EH985-90934, March 2011) - Page 44
from the replica copy on D2D-B and the CommServe disaster recovery tools, read the DR backup from the CommcellDR backup share on D2D-B, and recover the CommServe to the standby server. 2.
