Your backup target does not support this product version and needs to be upgraded

Challenge

During an upgrade from Veeam Endpoint Backup Free to Veeam Agent for Microsoft Windows 2.0, you receive the following warning:

Your backup target does not support this product version and needs to be upgraded

Cause

If Veeam Agent for Microsoft Windows is to be integrated with Veeam Backup & Replication, version 9.5 Update 2 of the latter is required.

During the upgrade, Veeam Agent for Microsoft Windows checks the latest backup made by Veeam Endpoint Backup Free and gets the information about Veeam Backup & Replication version.

However, Veeam Endpoint Backup Free is not aware of the updated Veeam Backup & Replication server unless a backup job has been run after the upgrade to 9.5 U2.

Solution

Either
disregard the warning message

or
run a backup with Veeam Endpoint Backup Free 1.5 to Veeam Backup & Replication before upgrading to Veeam Agent for Microsoft Windows 2.0.
