Windows agent updates can be pushed to assets from the appliance or manually installed for environments that do not support push installation.
See the following topics for details:
Pushing updates to Windows assets greatly reduces administration time and ensures that the latest protection software is running on your assets.
See the following topics for details:
Any time an agent update is available for Windows assets, a notification displays in the Alerts area of the global options toolbar. Once you install the update, remove the alert by selecting it and clicking delete icon. Note that alerts display only for assets that meet the push install requirements described below.
In addition to the general Windows agent requirements, the following prerequisites must be met before pushing the Windows agent:
Item |
Description |
---|---|
Windows versions supported |
Windows XP, 2003 and up are supported (32- and 64-bit). |
Credentials |
Trust credentials must be defined for the Windows server asset on the backup appliance. See Managing asset credentials for details. |
Windows environment |
The Windows machine must be configured as described in Windows configuration requirements. |
The following Windows configuration settings are required for the agent push feature:
• | Workstation and Server services must be running and set to automatic restart. |
• | For Windows Vista and later, Network discovery and Printer and File Sharing must be enabled for the current network profile (in Control Panel > Network and Sharing Center). |
• | For Windows XP Professional and 2003, File and Printer Sharing for Windows Networks must be enabled for the network adapter itself. Select Control Panel > Network and Sharing Center > Change Adapter Settings, right-click the adapter, select Properties and check File and Printer Sharing for Microsoft Networks. |
• | For Windows XP Professional, turn off Simple sharing in Control Panel > Folder Options > View > Use simple file sharing. |
• | Trust credentials entered on the Unitrends Add Asset page must have administrative privileges. On systems with user account controls (UAC) enabled, at least one of the following must also apply: |
– | The trust credentials entered are for a domain administrator account. |
– | The trust credentials entered are for a system administrator account. Being a different member of the Administrators group is insufficient. If the administrator account is disabled, enable it by executing the following in an elevated command prompt: net user administrator /active:yes |
– | Registry key LocalAccountTokenFilterPolicy must exist and be set to 1. |
• | Firewall rules must allow inbound and outbound traffic between both machines. Default Windows firewall rules limit many services to the subnet. If the backup appliance is outside the Windows asset's subnet, modify firewall Printer and File Sharing settings (TCP ports 139 and 445) to allow communication between the systems. |
• | For 32-bit assets only, the Windows machine must be configured with English as the default language. Select non-English default languages are supported for 64-bit machines. For a list of supported languages, see the Unitrends Compatibility and Interoperability Matrix. |
1 | Before installing agent updates, check for and install any appliance updates. For details, see To install appliance updates. |
2 | Select Configure > Protected Assets. |
3 | All protected assets display. Check the Agent Version to see the agent that is currently installed. |
4 | Do one of the following: |
– | To install available updates on all eligible assets, select Update Agent > Update All. |
– | To install available updates on a subset of eligible assets, check boxes to select assets to update, then select Update Agent > Update selected. |
5 | Updated agents are installed on all selected Windows assets meeting these conditions: |
• | Trust credentials are valid. |
• | No backup or recovery job is currently in progress or scheduled to run soon for the asset. |
• | Push update requirements have been met (see |
• | Updates are available for the asset (asset is not running the latest agent release). |
Use these procedures to manually update, move, or remove the Windows agent:
Install the latest agent version as described in Installing the Windows agent. It is not necessary to uninstall existing agent software.
If you are running out of space on C: or need to move the agent for some other reason:
1 | Uninstall the agent. See To remove or repair the Windows agent for details. |
Log files remain in the C:\PCBP directory.
2 | Move or delete the C:\PCBP directory as desired. |
3 | Manually install the agent in the desired location. See Installing the Windows agent for details. |
Note: 1100 MB of free space is required on the system drive (usually volume C:), even if you are installing to a different volume. This space is needed for the installer program to run.
Note: If you installed the agent using group policy, remove the agent using the command line. See Command-line installer for Windows agents for details.
Remove or repair the agent using the Windows Add/Remove Programs interface or by running the agent msi installer again. Select the Repair option to repair an agent or choose Remove to delete the agent.
