4. Check and verify on Backup Specification Options through Advanced button. Then in Filesystem Options section, click on Advanced. 5. 19 In Filesystem Options, click Other tab, make sure “Software compression” is unchecked, and “Data security” is set to None. Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.
Note: Always Disable ‘Software compression’, as DR Series Deduplication Appliance has compression built in and does not require any compression on HP Data Protector. In general, additional data compression on backup software will have negative impact on total savings on DR Series Deduplication Appliance. Set ‘Data security’ to None, as enabling encryption before the data stream is sent to the DR Series Deduplication Appliance device will make the data not deduplicatable.
7. Review the Backup Job Summary. Click Next. 8. Specify a name for the Backup Job. Click Save As to save the newly configured backup specification. 21 Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.
9. (This step and next are Optional: or wait for the scheduled backup run to complete.) Click Start Backup to run the backup. When the Start Backup window opens, click OK to start the backup. 10.

The Session Information window will tell you when the backup is completed. 22 Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.
4 Set up DR Native Replication & Restore from Target Container 4.1 Build Replication Relationship between DRs NOTE: The assumption is that on both the source and target DR, a container is already created for each of them. In this example it’s called “backup”. And the target container should not be used by anything else and is empty, with the same Connection Type as the source container. 11.
12. Select a local container as source container in Step 1, make appropriate selection in Step 2 and Step 3. In Step 4, select Map to container on remote system, enter credential to authenticate to Target DR (default is “Administrator/St0r@ge!), then click Retrieve Containers, select the target container on the list, click Create Replication. 13. Verify that the replication session is created. Peer State is Online.
4.2 25 Run backup to source DR (Optional: only when there is no backup data on the source DR container) 1. Add both source DR and target DR as Devices on HP DP, create a New Backup Job with source DR as the Target. 2. In Start Backup window, click OK to start the backup using the appropriate settings. Monitor job status. Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.
3. When backup job is completed, HP DP creates backup files using the suffix '.fd’ on source DR , and the ‘.fd’ files will be replicated to the target DR, as shown in screenshots. • Source DR • Target DR Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.
4.3 Prepare Replication Target for restore 4. On HP DP, Go to Devices & Media - > Media - > Pools, right- click the Media Pool associated with the source container device and the backup set that needs to be restored, click Export. NOTE: If the media pool is protected and cannot be exported, you should perform Recycle before Export 27 Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.
5. Under Devices & Media - > Devices, expand the source container device node, delete the device object that is associated with the backup set. 6. Open HP DP CLI console, use command utility “omnidownload” to download the source container library configuration from IDB NOTE: Please refer to Appendix C on how to use the command “omnidownload”. 28 Setting Up Dell™ DR Series Deduplication Appliance on HP® Data Protector 7.

5 Set Up the DR Series Deduplication Appliance Cleaner The cleaner will run during idle time. If you workflow does not have a sufficient amount of idle time on a daily basis then you should consider scheduling the cleaner which will force it to run during that scheduled time. If necessary you can do the following procedure as described in the screenshot to force the cleaner to run. Once all the backup jobs are setup the DR Series Deduplication Appliance cleaner can be scheduled.
6 Monitoring Deduplication, Compression and Performance After backup jobs have completed, the DR Series Deduplication Appliance tracks capacity, storage savings and throughput on the DR Series Deduplication Appliance dashboard. This information is valuable in understanding the benefits the DR Series Deduplication Appliance. Note: Deduplication ratios increase over time; it is not uncommon to see a 2- 4x reduction (25- 50% total savings) on the initial backup.
7 Appendix 7.1 Create a Storage Device for CIFS There are two options for HP Data Protector to authenticate to DR Series Deduplication Appliance through CIFS. DR joined into domain: Integrate HP Data Protector Server and DR Series Deduplication Appliance with Active Directory a. Ensure the AD user has appropriate ACLs to the DR Series Deduplication Appliance Container share b. Set the HP Data Protector service to run with this AD user 1. 2. a.
NOTE: Do this step only when no backups are currently running, as restarting the services causes backup jobs to fail. Double- click on the services one at a time. If you are using local synced accounts rather than the AD account, make sure that there is a “.\”in front of the user name. [move this before the step – that’s when the user needs this info] d. Click OK. e. After changing both services for HP Data Protector, choose Stop/Start to restart the two services.
7.2 Create a Storage Device for NFS For NFS backup using the HP Data Protector, a target folder needs to be created as NFS share directory. This is the location to which backup objects will be written. This is not required while adding CIFS share. 1. 2. 7.3 Mount the DR Series Deduplication Appliance NFS share onto the NFS share directory which backup objects will be written in the HP Data Protector environment. Verify the NFS share. One way is to try using the Linux command “cat /proc/mounts”.
