PowerProtect Data Manager 19.12 Microsoft SQL Server User Guide

Troubleshooting application-aware backup failure in multiple VLAN environment

In a Microsoft SQL Server environment of multiple virtual networks (VLANs) where each application client has access to only one network interface, an application-aware backup fails with the following error message:

PowerProtect agent for Microsoft Applications: Unable to update persisted settings for PowerProtect Data Manager host '<IP_address>': Exception 'Timeout was reached' occurred while sending Certificate Signing Request.

A Microsoft SQL Server application-aware backup is not supported in this type of multiple virtual network environment.

In a multiple virtual network environment, ensure that the Microsoft SQL Server application-aware host has network connectivity to both the management network and data network. The "Virtual networks (VLANs)" section in the PowerProtect Data Manager Administration and User Guide provides more details.
