puppet-netbackup

Overview

Puppet + NetBackup. Currently in development, contributions are welcome. See TODO

One of the goals of this module is unfortunately to try to provide an installation method that does not rely on a package manager, but rather leverages the installation methods provided by the vendor. However, this does not exclude the possibility of an installation method where package managers provide the neccessay rpms/debs/pkgs, yet that feature is still to be implemented.

TODO

• Server installation of master/media
• Tuning/parameterizing of master/media
• Policy creation/modification via puppet?
• Server facts
• Client facts
• Client upgrades
• ??

Classes

The netbackup module provides the following classes of interest

• netbackup::client - used for client installation and management
• netbackup::server::prepare - used for master/media server preparation. Applies best practices for tuning such as changing sysctl and ulimit parameters.
• netbackup::server::tune - applying values to the "touch files" used in netbackup for buffer settings etc, reasonable values set by default

Client

Installs the client as neccessary on UNIX/Linux hosts, unfortunately using quite ugly expect script.

The netbackup::client class is used for management of NetBackup client. If no NetBackup client is present, it will try to run the NetBackup installer located at installer (should preferably be an NFS mount).

• installer - full path to the install binary provided from NetBackup DVD
• version - run install unless a client of this version is already installed
• masterserver - which masterserver should be entered upon installation of client
• mediaservers - mediaservers which has access to a client
• service_enabled - start netbackup, true or false?
• excludes - array of excludes to put in exclude list

Example usage

Sample definition:

class { 'netbackup::client':
    installer       => '/path/to_nfs_share/NetBackup_7.6.0.1_CLIENTS2/install',
    version         => '7.6.0.1',
    service_enabled => true,
    masterserver    => 'netbackup.xyz.com',
    mediaservers    => ['mediasrv1.xyz.com', 'mediasrv2.xyz.com'],
    excludes        => ['/tmp', '/other/excluded/path'],
}

Server

Only handles preparation for NetBackup Master/media installation for now, see netbackup::server::prepare.

Example usage

class { 'netbackup::server::prepare': }

Facts

• netbackup_client_name - returns the client name from /usr/openv/netbackup/bin/nbgetconfig
• netbackup_serverlist - returns a list of servers retreived from /usr/openv/netbackup/bin/nbgetconfig
• netbackup_version - returns a string containing version information found in /usr/openv/netbackup/bin/version, nil if the file is not found or it does not contain a version string

Limitations

Only tested on Linux (CentOS/Ubuntu) for now.

Development

Standard GitHub workflow, i.e.

1. Fork/branch
2. Send PR
3. Wait for response
