![]() The trust credentials entered are for a system local administrator account. The trust credentials entered are for a domain administrator account. On systems with user account controls (UAC) enabled, at least one of the following must also apply: Trust credentials entered in the Add Asset dialog in the Unitrends UI must have administrative privileges. įor Windows 7 and later, Network discovery and Printer and File Sharing must be enabled for the current network profile (in Control Panel > Network and Sharing Center).(To configure your appliance to use SMB 2.0, see How Unitrends supports SMBv2.) Note: Upgrading from a pre-10.4.8 version does not change the SMB 1.0 setting. The Windows machine must be configured as described in Windows configuration requirements. See Managing asset credentials for details. Trust credentials must be defined for the Windows server asset on the backup appliance. To resolve this issue, see the following Microsoft knowledge base article: The "Untrusted publisher" dialog box appears when you install a driver in Windows 7 or Windows Server 2008 R2. Note: A known Microsoft issue may prevent successful agent push install on Windows 7 and Windows 2008 R2 systems. Windows agent push is NOT supported for Azure virtual machines. Windows Workstation – 64-bit Windows 7 and later versions listed in the Compatibility and Interoperability Matrix are supported. Windows Server – 64-bit Windows 2008 R2 and later versions listed in the Compatibility and Interoperability Matrix are supported. In addition to the general Windows agent requirements, the following prerequisites must be met to push-install the Windows agent: To protect Hyper-V clusters, SQL clusters, or file server clusters with the secure agent pairing feature: If upgrading from a pre-10.6.9 agent release, backups may fail until the pairing completes successfully (this can take up to two hours). Ensure that port 888 is not in use on the Windows asset. ![]() The Windows agent listens for pairing requests on port 888. Please ensure that the Agent software is installed on assetName, the Agent service is running (if applicable), and no firewall settings are preventing access. The Unitrends System could not connect to the Unitrends Agent on assetName. If you attempt this, you receive an error similar to: Failed to save client: Registration for client assetName failed. You cannot add an asset that is running a 10.6.6 or higher agent to an appliance that is running an older release. Jobs will fail if you attempt to protect a 10.6.6 or higher agent with an appliance that is running an older release. Important! Be sure to upgrade your Unitrends appliance before upgrading your Windows agents. The Unitrends appliance version must be equal to or higher than the Windows agent version. The Windows asset must be running agent release 10.6.6 or higher. The Unitrends appliance must be running release 10.6.6 or higher. These secure pairing requirements must be met to protect Windows assets with agent release 10.6.6 or higher: Communication between appliances and agents is only allowed if there is a matching (paired) certificate. This pairing enables Transport Layer Security (TLS) to encrypt data and authenticate connections between appliances and agents. Secure agent pairing requirements – Beginning in release 10.6.6, a secure pairing is automatically established between the appliance and the Windows agent on each of its protected assets. If there is a firewall between your appliance and the agent, ports 17 must be open for the TCP protocol. VSS Hyper-V Writer is required for the Hyper-V agent. ![]() VSS SQL Writer is required for the SQL Server agent. VSS Exchange Writer is required for the Exchange agent. To protect Exchange, SQL Server, or Hyper-V, the following VSS writers are required: The Windows Volume Shadow Copy Service (VSS) framework must be installed. Single Instance Storage (SIS) on Windows Storage Server 2008 is not supported and must be disabled for the agent to properly perform backups.
