Securing the connection to NetBackup Snapshot Manager for Data Center

  • Supported scenarios:

    • Primary server and Snapshot Manager for Data Center must be with ECA or NBCA.

    • For NBCA and ECA mixed mode continue with ECA mode for NetBackup Snapshot Manager for Data Center installation.

  • Unsupported scenario: Primary with NBCA and NetBackup Snapshot Manager for Data Center with ECA and vice versa.

In the NetBackup Snapshot Manager for Data Center, you can upload CRLs of the external CA at /cloudpoint/eca/crl file. The uploaded CRL does not work, if the crl directory is not present or is empty.

The following three parameters are tuneable, you can add the entry under the  eca section in the /cloudpoint/flexsnap.conf file.

Commands

CA migration

  • NBCA to ECA:

    # flexsnap_configure renew --ca /eca2/trusted/cacerts.pem --key /eca2/private/key.pem --chain /eca2/cert_chain.pem
    Enrolling external CA certificates with NetBackup...
    Snapshot Manager certificate is renewed.
  • ECA to NBCA:

    # flexsnap_configure renew --token <reissue-token>
    Generating new NetBackup Host-ID certificate...
    Snapshot Manager certificate is renewed.

Post revoke certificate regeneration for NBCA

# flexsnap_configure renew --token <reissue-token>
Generating new NetBackup Host-ID certificate...
Snapshot Manager certificate is renewed.

Post revoke certificate regeneration for ECA

# flexsnap_configure renew --ca /eca2/trusted/cacerts.pem --key /eca2/private/key.pem --chain /eca2/cert_chain.pem
Enrolling external CA certificates with NetBackup...
Snapshot Manager certificate is renewed.

Post migration regenerated certificates for ECA/NBCA

# flexsnap_configure renew --hostnames new-nbsm.veritas.com --token <authentication-token>
Generating new NetBackup Host-ID certificate...
Snapshot Manager certificate is renewed.
 
Please run 'flexsnap_configure renew --internal --hostnames <nbsm_fqdn>

Certificate regeneration for extension

# flexsnap_configure renew --extension --primary <nbsm_fqdn> --token <extension_token>

Certificate rotation

# flexsnap_configure renew --force
Generating new NetBackup Host-ID certificate...
Snapshot Manager certificate is renewed.
