NetBackup™ for Microsoft SharePoint Server Administrator's Guide

Reviewing the auto-discovered mappings

In certain scenarios, a NetBackup host shares a particular name with other hosts or has a name that is associated with a cluster. To successfully perform backups and restores with NetBackup for SharePoint Server, you must approve each valid auto-discovered mapping that NetBackup discovers in your environment. Or, manually add the mappings.

See Approve the auto-discovered mappings for a cluster.

See Manually map host names.

Examples of the configurations that have multiple host names include:

  • A host is associated with its fully qualified domain name (FQDN) and its short name or its IP address.

  • For SharePoint Server, the nodes in a clustered back-end SQL Server are associated with the virtual name of the SQL Server.

These mappings are configured in the Security > Host mappings node in the NetBackup web UI. You can also use the nbhostmgmt command to manage the mappings. See the NetBackup Security and Encryption Guide and NetBackup Web UI Administrator's Guide for more details.

Auto-discovered mappings for a cluster

If you have a clustered back-end SQL Server, you must map the node names to the virtual name of the cluster if the following apply:

  • If the backup policy includes the cluster name (or virtual name)

  • If the NetBackup client is installed on more than one node in the cluster, the virtual name must be mapped to each node.

    If the NetBackup Client is only installed on one node, then no mapping is necessary.

Approve the auto-discovered mappings for a cluster

To approve the auto-discovered mappings for a cluster

  1. In the NetBackup web UI, expand Security > Host mappings.
  2. Click the Mappings to approve tab.

    The list displays the hosts in your environment and the mappings or additional host names that NetBackup discovered for those hosts. A host has one entry for each mapping or name that is associated with it.

    For example, for a cluster with hosts client01.lab04.com and client02.lab04.com, you may see the following entries:

    Host

    Auto-discovered mapping

    client01.lab04.com

    client01

    client01.lab04.com

    clustername

    client01.lab04.com

    clustername.lab04.com

    client02.lab04.com

    client02

    client02.lab04.com

    clustername

    client02.lab04.com

    clustername.lab04.com

  3. Click the name of the host.
  4. Review the mappings for the host and click Approve if you want to use the discovered mappings.

    For example, if the following mappings are valid for client01.lab04.com, then you approve them.

    Auto-discovered mapping

    Valid name for

    client01

    The short name of the client

    clustername

    The virtual name of the cluster

    clustername.lab04.com

    The FQDN of the virtual name of the cluster

  5. When you finish approving the valid mappings for the hosts, click on the Hosts tab.

    For hosts client01.lab04.com and client02.lab04.com, you see entries for Mapped host or IP address that are similar to the following:

    Host

    Mapped host names/IP addresses

    client01.lab04.com

    client01.lab04.com, client01, clustername, clustername.lab04.com

    client02.lab04.com

    client02.lab04.com, client02, clustername, clustername.lab04.com

  6. If you need to add a mapping that NetBackup did not automatically discover, you can add it manually.

Approve the auto-discovered mappings for a SharePoint SQL Server availability group backup and restore

To approve the auto-discovered mappings for a SharePoint SQL availability group

  1. In the NetBackup web UI, expand Security > Host mappings.
  2. Click the Mappings to approve tab.

    The list displays the hosts in your environment and the mappings or additional host names that NetBackup discovered for those hosts. A host has one entry for each mapping or name that is associated with it.

    For example, for a SharePoint SQL Server with hosts client01.lab04.com and client02.lab04.com, you may see the following entries:

    Host

    Auto-discovered mapping

    client01.lab04.com

    client01, clustername, clustername.lab04.com

    client01.lab04.com

    aglistenername

    client01.lab04.com

    aglistenername.lab04.com

    client02.lab04.com

    client02, clustername, clustername.lab04.com

    client02.lab04.com

    aglistenername

    client02.lab04.com

    aglistenername.lab04.com

  3. Click the name of the host.
  4. Review the mappings for the host and click Approve if you want to use the discovered mappings.

    For example, if the following mappings are valid for client01.lab04.com, then you approve them.

    Auto-discovered mapping

    Valid name for

    client01

    The short name of the client

    aglistenername

    The listener name of the SharePoint SQL Server availability group

    aglistenername.lab04.com

    The FQDN of the listener name of the SharePoint SQL Server availability group.

  5. When you finish approving the valid mappings for the hosts, click on the Hosts tab.

    For hosts client01.lab04.com and client02.lab04.com, you see entries for Mapped host or IP address that are similar to the following:

    Host

    Mapped host names/IP addresses

    client01.lab04.com

    client01.lab04.com, client01, aglistenername, aglistenername.lab04.com

    client02.lab04.com

    client02.lab04.com, client02, aglistenername, aglistenername.lab04.com

  6. If you need to add a mapping that NetBackup did not automatically discover, you can add it manually.
Manually map host names

If you need to add a mapping that NetBackup did not automatically discover, you can add it manually.

To manually map host names

  1. In the NetBackup web UI, expand Security > Host mappings.
  2. Click on the Hosts tab.
  3. Click Add shared or cluster mappings.

    For example, type the name of the virtual name of the cluster. Then click Add to choose the hosts to which you want to map that virtual name.
