Validating SSH Fingerprints

When you select the Add unknown hosts to the list manually option in Veeam Backup & Replication settings, you need to validate SSH fingerprints of untrusted Linux servers and Linux VMs manually in the Veeam Backup & Replication console. For more information about all SSH fingerprint verification options, see Linux Hosts Authentication.

Validating Linux VMs

During discovery, Veeam Backup & Replication puts untrusted Linux VMs to the Untrusted node in the inventory pane. You can validate all untrusted VMs at once or a specific VM:

• To validate all untrusted Linux VMs at once, select the Untrusted node and click Trust All on the ribbon. Alternatively, you can right-click the Untrusted node and select Trust all.

• To validate a specific VM, select it in the working area and click Trust on the ribbon. Alternatively, you can right-click the VM and select Trust.

Validating Linux Servers

If the SSH public key fingerprint of a Linux server is changed, Veeam Backup & Replication puts this machine to the Unavailable node in the Backup Infrastructure view. To validate the Linux server, do the following:

1. Right-click the Linux server and select Properties.
2. In the SSH Connection step of the Edit Linux Server wizard, click Apply.
3. In the dialog box, click Yes to confirm that you trust this server.
4. Click Finish to close the wizard.
