Preparing a storage system for basic NDMP backup application management

About NDMP preparation  Top

To enable a storage system for basic management by a commercial NDMP backup application, you must enable the storage system's NDMP support, specify the backup application's configured NDMP version, host IP address, and authentication method. If an operator without root privileges to the storage system is using a backup application, a storage system-generated NDMP-specific password must be used by that user to carry out backup operations on that storage system.

To prepare a storage system for NDMP management, complete the following steps.

Step

Action

1

Enable NDMP. At the console command line of target storage system, enter:

ndmpd on

For details see Enabling or disabling NDMP service.

2

Specify the NPMD version to support on your storage system. The version must match the version configured for your NDMP backup application. Enter:

ndmpd version {2|3|4}

For details see Specifying a preferred network interface.

3

If you want to specify a restricted set of NDMP backup application hosts that can connect to the filer, enter:

options ndmpd.access hosts

hosts is a comma-separated list of host names or IP addresses of nodes permitted to start NDMP sessions with the storage system.

If you do not wish to restrict NDMP access to this storage system by host, do not set this option. By default NDMP does not restrict access by host.

For details see Specifying NDMP access by host or interface.

4

Specify the authentication type (plaintext, challenge, or plaintext and challenge) required for an NDMP connection to this storage system. For example:

options ndmpd authtype plaintext,challenge

This setting must include the authentication type supported by the NDMP backup application.

For details see Specifying the NDMP authentication type.

5

If operators without root privilege on the storage system will be carrying out tape backup operations through the NDMP backup application

  • Make sure they have a useradmin account on the storage system. If they do not, enter:
    useradmin useradd username
    
  • Display that user's system-generated NDMP-specific password. Enter:
    ndmpd password username
    

    When running the NDMP backup application, the user must input this NDMP-specific password to connect to this storage system and carry out NDMP backup and restore operations.

    For details, see Generating an NDMP-specific password for non-root administrators.
