Configuration options for external CA-signed certificates

To configure a NetBackup primary server, media server, or client to use external CA-signed certificate for host communication, you must define certain configuration options in the NetBackup configuration file (bp.conf on UNIX platform or Windows registry).

About the mandatory and optional configuration options
  • For external certificate configuration, for file-based certificates, the following configuration options are mandatory:

    • ECA_CERT_PATH

    • ECA_TRUST_STORE_PATH

    • ECA_PRIVATE_KEY_PATH

      If the private key of the external certificate is encrypted, ECA_KEY_PASSPHRASEFILE is also mandatory:

  • For Windows certificate store, the following configuration options are mandatory:

    • ECA_CERT_PATH

  • The following options are optional:

    • ECA_CRL_CHECK

      If the option is set to DISABLE (or 0) the ECA_CRL_PATH option is ignored and revocation status of a peer host's certificate is not verified.

      If the option is set to a value other than DISABLE and 0, revocation status of a peer host's certificate is verified based on ECA_CRL_PATH.

    • ECA_DR_BKUP_WIN_CERT_STORE

      For Windows certificate store, specify this option if you want to backup the external certificates during catalog backup.

    • ECA_CRL_PATH_SYNC_HOURS

      This option is used when ECA_CRL_CHECK is enabled and ECA_CRL_PATH is defined.

    • ECA_CRL_REFRESH_HOURS

      This option is used when ECA_CRL_CHECK is enabled, but ECA_CRL_PATH is not defined (when CDP is used as a CRL source).
