Ever wanted to chage your managed server from an IP Adress or DNS (shortname) to FQDN. Then you will find this article very useful.
Since the move to version Veeam Backup & Replication (VBR) v13, we have seen that FQDN works more reliably in VBR/VSA due to strict reverse DNS requirements for certificate authentication, SSH, and agent deployment on Linux. IPs skip PTR lookups and often fail validation as demonstrated in this guide “Building VIHR: Ransomware-Proof Repository with Veeam JeOS“. In this article, we shall discuss how to “Switch from IP to DNS names for Backup Infrastructure in VBR cleanly”
Managed Server Object Rename
Prior to running the commands below you need to identify the Name\FQDN\IP Veeam is using to communicate with the Managed Server currently. In place of Techda01, you could enter an IP address if this is what your managed server uses until now.
# Step 1: Assign the target infrastructure component object to a variable
$Server = Get-VBRServer -Name “Techda01”
$Server = Get-VBRServer -Name “192.168.2.147” (in case you have an IP address in the name field)
# Step 2: Push the new FQDN update directly into the VBR configuration database
$Server.SetName(“techda01.techdc01.techdirectarchive.com”)
