NetBackup™ Network Ports Reference Guide

NetBackup deduplication ports

The following table shows the ports that are used for NetBackup deduplication that includes Media Server Deduplication (MSDP), and optimized deduplication. If firewalls exist between the various deduplication hosts, you must open the required ports.

Deduplication hosts are the media servers, deduplication storage servers, any load balancing servers, and any clients that deduplicate their own data.

Note:

MSDP with Client-Direct (client deduplication) and optimized duplication need some ports to be opened.

During Client Direct restores, TCP port 1556 must be open between the NetBackup client and the master server.

This is the NetBackup Deduplication Engine (spoold) port that is used by MSDP. Open this port between:

  • The deduplication client and the storage servers.

  • The MSDP and the storage servers.

This is the NetBackup Deduplication Manager (spad) port that is used by MSDP. Open this port between:

  • The deduplication client and the MSDP servers.

  • The MSDP server and any Additional servers that handle finger printing.

Ports 10082 and 10102 (MSDP) must also be open between the media server and any storage servers that perform optimized duplications.
