3 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.
4 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.
A Appendix A.1 Authenticating to DR through CIFS There are two options for NVBU to authenticate to DR Series Deduplication Appliance through CIFS. DR joined into domain: Integrate NVBU 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 NVBU 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 workgroup account rather than the AD account, make sure that there is a “.\”in front of the user name. d. Click OK. e. After changes, choose Stop/Start to restart the services. 24 Setting Up Replication between Dell™ DR Series Deduplication Appliances with NetVault 9.
