By | December 27, 2015

As I descirbed some months ago, NetBackup Access Control (NBAC) can be used to limit access to NetBackup more granular. Since NetBackup 7.x. the configuration of NBAC is simplified. NBAC should be configured on the following NetBackup components:

  • Master Server
  • Media Servers
  • Clients

  1. Run the bpnbaz -setupmaster command. Type y to continue the configuration wizard.How to configure NetBackup Access Control (NBAC) Master

NBAC Permissions

As you could notice, during the configuration of NBAC, the USE_VXSS was left in AUTOMATIC mode. This option specifies whether the local system uses NetBackup product authentication and authorization. It is recommended to use the REQUIRED mode so you should change it on Master, Media Servers and Clients as well. To change please navigate to NetBackup Management --> Host Properties --> Master Servers or Media Servers or Clients, select host and double click. Then click on Access Control and select Required mode. Click OK. Restart NetBackup services on the target host.How to configure NetBackup Access Control (NBAC) Required

Now you can specify users and permissions for them. There are some pre-defined NBAC groups

  • NBU_User
  • NBU_Operator
  • NBU_Admin
  • NBU_Security Admin
  • Vault_Operator
  • NBU_SAN Admin
  • NBU_KMS Admin

You need to add the required users to the required groups within the Access Management tab. If users do not have required permissions, a similar error is received:

To add users to a group, click on the group and specify user or group that you want to add:

Conclusion

The NetBackup Access Control (NBAC) offers you higher security and permission granularity but also more complexity of your backup environment. Sometimes, it's better (and easier) to just limit access to the NetBackup Machine 🙂
