Validating SSH Fingerprints

Veeam Backup & Replication treats fingerprints of Linux VMs and Linux hosts differently:

Validating SSH Fingerprints of Linux VMs

When you enable the Add unknown hosts to the list manually (more secure) option in Veeam Backup & Replication settings, Linux-based computers whose fingerprints are not stored in the Veeam Backup & Replication database or the known_hosts file become unable to communicate to the Veeam backup server. During discovery, Veeam Backup & Replication puts such computers to the Untrusted protection group. To start managing an untrusted computer, you need to validate its fingerprint manually in the Veeam Backup & Replication console.

To validate the SSH fingerprint:

  1. Open the Inventory view.
  2. In the inventory pane, expand the Virtual Infrastructure node and click Untrusted.
  3. In the working area, Veeam Backup & Replication will display a list of computers whose fingerprints need to be validated. Check fingerprints of the computers in the list and validate them in one of the following ways:

    • To validate a fingerprint of a specific computer in the list, select the necessary computer in the working area and click Trust on the ribbon. Alternatively, you can right-click the computer and select Trust.

Validating SSH Fingerprints of Linux Hosts

If the SSH public key fingerprint of a Linux host is changed, Veeam Backup & Replication places this host in the Unavailable folder. To be able to use this server, do the following:

  1. In the Backup Infrastructure view, expand the Managed Servers node and select Unavailable.
  2. Right-click the Linux server and select Properties.
  3. In the SSH Connection step of the Edit Linux Server wizard, click Apply.
  4. In the pop-up dialogue window, click Yes to confirm that you trust this server.
  5. Click Finish to close the wizard.
