Veritas NetBackup™ Deduplication Guide

The following are prerequisites for using the Universal Share MSDP build-your-own (BYO) server feature:

• The Universal Share is supported on an MSDP BYO storage server with Red Hat Enterprise Linux 7.6, 7.7, 7.8, or 7.9.

• NFS services are installed and running if you want to use the share over NFS

• Samba services are installed and running if you want to use share over CIFS/SMB.

  You must configure Samba users on the corresponding storage server and enter the credentials on the client.

  • If the Samba service is part of a Windows domain, the Windows domain users can use the Samba share. In this scenario, credentials are not required to access the share.

  • If the Samba service is not part of Windows domain, perform the following steps:

    • For a NetBackup Appliance, local users are also Samba users. To manage local users, log in to the CLISH and select Main > Settings > Security > Authentication > LocalUser. The Samba password is the same as the local user's login password.

    • For an MDSP BYO server, create a Linux user (if one does not exist). Then, add the user to Samba.

      For example, the following commands create a test_samba_user use for the Samba service only:

      # adduser --no-create-home -s /sbin/nologin test_samba_user

      # smbpasswd -a test_samba_user

      To add an existing user to the samba service, run the following command:

      # smbpasswd -a username

• NGINX is installed and running.

  • Installing NGINX from Red Hat Software Collections:

    • Refer to https://www.softwarecollections.org/en/scls/rhscl/rh-nginx114/ for instructions.

      Because the package name depends on the NGINX version, run yum search rh-nginx to check if a new version is available. (For NetBackup 8.3, an EEB is required if NGINX is installed from Red Hat Software Collections.)

  • Installing NGINX from the EPEL repository:

    • Refer to https://fedoraproject.org/wiki/EPEL for installation instructions of the repository and further information.

      The EPEL repository is a volunteer-based community effort and not commercially supported by Red Hat.

  • The NGINX version must be same as the one in the corresponding official RHEL version release. You need to install it from the corresponding RHEL yum source (epel).

  • Before you start the storage configuration, ensure that the new BYO NGINX configuration entry /etc/nginx/conf.d/byo.conf will be included as part of the HTTP section of the original /etc/nginx/nginx.conf file.

  • If SE Linux has been configured, ensure that the policycoreutils and policycoreutils-python packages are installed from the same RHEL yum source (RHEL server), and then run the following commands:

    • semanage port -a -t http_port_t -p tcp 10087

    • setsebool -P httpd_can_network_connect 1

    Enable the logrotate permission in SE Linux using the following command:

    semanage permissive -a logrotate_t

• Ensure that the /mnt folder on the storage server is not mounted by any mount points directly. Mount points should be mounted to its subfolders.
