Preparing a filer for basic NDMP backup application management

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

ndpmd on

For details see Enabling or disabling NDMP service.

Specify the NPMD version to support on your filer. 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.

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 filer.

If you do not wish to restrict NDMP access to this filer 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.

Specify the authentication type (plaintext, challenge, or plaintext and challenge) required for an NDMP connection to this filer. 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.

If operators with non-root privilege on the filer will be carrying out tape backup operations through the NDMP backup application:

• Make sure they have a useradmin account on the filer. 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 filer and carry out NDMP backup and restore operations.

  For details, see Obtaining a generated NDMP-specific password for non-root administrators.
