About compression and encryption
■For the initial full backups of your clients, use the deduplication storage server. For subsequent backups, use load balancing servers.
Do not expect the deduplication storage server to be the media server that is used for restores to that client. If a media server deduplicates a client backup, your restore settings may require that the media server also be used for restores to that client.
■Enable
If a client cannot tolerate the deduplication processing workload, be prepared to move the deduplication processing back to a server.
See “About deduplication performance” on page 32.
About compression and encryption
For compression or encryption, Symantec recommends that you enable them so they occur during the NetBackup deduplication process. If you compress or encrypt the data before it is deduplicated, deduplication rates are low.
See “About the deduplication configuration file” on page 60.
See “Editing the deduplication configuration file” on page 60.
See “pd.conf file settings” on page 61.
About optimized duplication of deduplicated data
Optimized duplication of deduplicated data reduces the amount of data that is transmitted over your network. Therefore, you can use optimized duplication for
Only the unique data segments are transferred.
