About the certificate to use to add a trusted primary server
A source or a target primary server may use NetBackup CA-signed certificates (host ID-based certificates) or external CA-signed certificates.
For more information on NetBackup host ID-based certificates and external CA support, refer to the NetBackup Security and Encryption Guide.
To establish trust between source and target primary servers, NetBackup verifies the following:
|
Can the source primary server establish trust using an external CA-signed certificate? |
If the external CA configuration options - ECA_CERT_PATH, ECA_PRIVATE_KEY_PATH, and ECA_TRUST_STORE_PATH - are defined in the NetBackup configuration file of the source primary server, it can establish the trust using an external certificate. In the case of the Windows certificate trust store, only the option ECA_CERT_PATH is defined. |
|
Which certificate authorities (CA) does the target primary server support? |
The target primary server may support external CA, NetBackup CA, or both. |
The following table lists the CA support scenarios and the certificate to use to establish trust between the source and the target primary servers.
Table: Certificate to be used for trust setup
Source primary server capability to use external certificate | CA usage of the target primary server | Certificate to be used for trust setup |
|---|---|---|
|
Yes The source primary server can use NetBackup CA and external CA for communication with a remote primary server |
External CA |

|
No The source primary server can use only NetBackup CA for communication with a remote maser server |
External CA |
