ECA_TRUST_STORE_PATH for NetBackup servers and clients
The ECA_TRUST_STORE_PATH option specifies the file path to the certificate bundle file that contains all trusted root CA certificates.
This certificate file should have one or more certificates in PEM format.
Do not specify the ECA_TRUST_STORE_PATH option if you use the Windows certificate store.
The trust store supports certificates in the following formats:
PKCS #7 or P7B file having certificates of the trusted root certificate authorities that are bundled together. This file may either be PEM or DER encoded.
A file containing the PEM encoded certificates of the trusted root certificate authorities that are concatenated together.
This option is mandatory for file-based certificates.
The root CA certificate in Cloudera distribution can be obtained from the Cloudera administrator. It may have a manual TLS configuration or an Auto-TLS enabled for the Hadoop cluster. For both cases, NetBackup needs a root CA certificate from the administrator.
The root CA certificate from the Hadoop cluster can validate the certificates for all nodes and allow NetBackup to run the backup and restore process in case of the secure (SSL) cluster. This root CA certificate is a bundle of certificates that has been issued to all such nodes.
Certificate from root CA must be configured under ECA_TRUST_STORE_PATH in case of self-signed, third party CA or Local/Intermediate CA environments. For example: In case of AUTO-TLS enabled Cloudera environments, you can typically find the root CA file named with cm-auto-global_cacerts.pem at path /var/lib/cloudera-scm-agent/agent-cert. For more details, refer Cloudera documentation.
Table: ECA_TRUST_STORE_PATH information
Usage | Description |
|---|---|
Where to use | On NetBackup servers or clients. If certificate validation is required for VMware, RHV servers, or Nutanix AHV, this option must be set on the NetBackup primary server and respective access hosts, irrespective of the certificate authority that NetBackup uses for host communication (NetBackup CA or external CA). If certificate validation is required for VMware, or RHV servers this option must be set on the NetBackup primary server and respective access hosts, irrespective of the certificate authority that NetBackup uses for host communication (NetBackup CA or external CA). |
How to use | Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option. For information about these commands, see the NetBackup Commands Reference Guide. Use the following format: ECA_TRUST_STORE_PATH = Path to the external CA certificate For example: |
Equivalent Administration Console property | No equivalent exists in the NetBackup Administration Console host properties. |
