About push installation

The push installation method lets you install one or more software packages on remote machines. You can use this method to install or upgrade the NetVault Backup Client software and NetVault Backup plug-ins on multiple machines, including Windows-based and Linux-based machines. Push installation is available for Windows-to-Windows, Windows-to-Linux, Linux-to-Linux, and Linux-to-Windows scenarios.

You can run push installation tasks from the NetVault Backup WebUI. When the task starts, a deployment agent is installed on the remote machines. The agent copies the installation packages from a shared location and performs silent installations on the machines. The agent also sends status messages to the server. By default, the client logs are preserved on the target machine. For more information about how to modify this setting, see Configuring default settings for Deployment Manager. You can view the task status from the WebUI. After the packages are successfully installed on the machines, the WebUI automatically adds the new clients to the NetVault Backup Server.

By default, NetVault Backup runs a maximum of 50 concurrent push-installation processes. You can modify the default settings to increase the number of concurrent processes. For more information, see Configuring default settings for Deployment Manager.

Prerequisites

Before you start the push installation procedure, verify that the following requirements are met:

Copy the packages to a shared location: Copy the client and plug-in packages to a shared location. Only CIFS shares, including Linux Samba Shares, are currently supported as package stores. The path must be accessible to the NetVault Backup Server and all target machines where you want to install the packages.
Configure a package store in NetVault Backup: After copying the installation packages, configure the shared location details in NetVault Backup. For more information, see Configuring a package store.
Configure the preferred network address setting on multihomed NetVault Backup Servers: On multihomed NetVault Backup Servers, configure the Preferred Network Address setting to allow the remote clients to send status messages to the correct address. For more information about this setting, see Configuring network addresses for multihomed machines.
Verify that the firewall is configured to allow traffic through the ports required for push installation: To push the client and plug-in packages to a remote Windows machine, the NetVault Backup Server establishes the initial WMI session with the remote machine using RPC over port 135. All further WMI traffic uses the dynamic port range of 49152 through 65535.

When pushing the NetVault Backup client installation to a Linux machine, you need the following additional prerequisites:

Grant the proper access: The user must have root-level access, with the NOPASSWD flag set in the sudoers file on the remote Linux machine. To complete this prerequisite, add one of the following entries to the sudoers file:
Affirm the password authentication: In the sshd_config file, set the PasswordAuthentication entry to yes.
Install libstdc++: If you are pushing the hybrid installation package of the NetVault Backup client on a 64-bit Linux machine, you must first install the 32-bit version of libstdc++.

When you push the NetVault Backup client from a Linux machine to Windows machine, you need the following additional prerequisites:

Ensure the WinRM version is greater than 2.0.

Managing package stores

This section includes the following topics:

Configuring a package store

A package store is a shared location used for storing NetVault Backup Client and plug-in binary files for push installations. Only CIFS shares, including Linux Samba shares, are currently supported as package stores. You can set up a package store in NetVault Backup by providing the path and user credentials for the CIFS share.

1
In the Navigation pane, click Guided Configuration, and then on the NetVault Configuration Wizard page, click Install Software/Add Clients.
2
On the Machines to Be Added as Clients page, click Install Software.
3
Click Manage Stores, and provide the following details.

Store Name

Provide a display name for the package store.

You cannot change the store name after it is configured.

Type

Select CIFS.

Location

Provide the UNC (uniform naming convention) path of the CIFS (Common Internet File System) share.

The format for specifying the path for Windows-based server is:

\\<server>\<share name>

The format for specifying the path for Linux-based server is:

NOTE: //<server>/<share name>To reduce the time it takes to browse the package store for automatic upgrades, locate the shared folder in a minimal directory hierarchy.

Verify that the path is accessible to the NetVault Backup Server and all target machines where you want to install the packages.

NOTE: On the Windows-based server, if the server IP address is used to configure a local package store (for example, \\10.11.12.3\PkgStore), the user credentials are not validated when the package store is added or updated. If you specify invalid credentials, no errors are reported. However, the deployment task fails if the authentication fails and the packages cannot be retrieved from the store. Therefore, Quest recommends that you use the server name when configuring the path to a local store (for example, \\WinServer1\PkgStore).

User Name

Specify a user account that can be used to access the CIFS share using one of the following formats:

Password

Specify the password for the user account.

Click Add to add the store, and then click OK.
