About the NetBackup Media Server Deduplication Option
About deduplication server requirements
All hosts that are used for deduplication must be NetBackup 7.0 or later. Hosts include the master server, the media servers, and the clients.
The computer’s CPU and memory constrain how many jobs can run concurrently.
Table | Deduplication server minimum requirements |
Hardware | Requirement |
CPU | CPU speed is the most important factor for performance. Minimum |
| CPU speed should be 2.2 GHz. |
| The deduplication storage server should have a minimum of 4 CPU |
| cores. Symantec recommends eight cores. |
| Symantec recommends Intel, AMD, and Sun SPARC processors (in |
| order of effectiveness). |
RAM | Symantec recommends 4 GBs of memory minimum. |
Operating system | The operating system must be a supported |
| For supported systems, see the NetBackup Release Notes. |
Note: Symantec recommends that you do not use the master server as a deduplication storage server. Master server activity and media server deduplication activity on the same host degrades performance.
Note: Symantec recommends that you do not use an existing media server for deduplication. Similarly, Symantec recommends that you do not repurpose older host hardware for deduplication.
About media server deduplication limitations
NetBackup media server deduplication and Symantec Backup Exec deduplication cannot reside on the same host. If you use both NetBackup and Backup Exec deduplication, each product must reside on a separate host.
NetBackup deduplication components cannot reside on the same host as a PureDisk Deduplication Option (PDDO) agent. Therefore, you cannot use the same media server for both NetBackup deduplication and as a PDDO host.
You cannot upgrade to NetBackup 7.0 or later a NetBackup media server that hosts a PDDO agent. If the NetBackup 7.0 installation detects the PDDO agent,
