DNS settings

DNS settings must be configured for the Unitrends system to connect to the Internet. In addition, DNS configuration allows the seamless resolution of fully qualified domain names (FQDN) for computers to short names, and vice versa.

ClosedDNS registration for Windows, Linux, and Mac clients

Beginning in release 7.2, you can choose to add a Windows client to the backup system by entering a static IP address, or by relying on DNS to facilitate the connection. To use DNS, both the backup system and Windows agent must be running release 7.2 or higher. Releases 7.3 and higher support DNS for Linux and Mac clients. Both the backup system and Linux or Mac agent must be running release 7.3 or higher to use DNS. DNS-only registration is supported only for Windows, Linux, and Mac clients.

Consider the following when registering clients by DNS:

• If you do not enter a static IP, make sure that both the client and the backup system have DNS entries and that reverse lookup is configured.
• For clients that utilize DHCP for IP address assignment, DNS-only registration should be used.
• If you supply a static IP, the system attempts to connect using that address but will attempt DNS hostname lookup if the static IP connection fails.
ClosedTo configure DNS settings
1 Select Settings > Clients, Networking, and Notifications > Networks > DNS.
2 Enter the IP of the DNS server in the DNS Server Address field and click Add.

Multiple DNS servers can be added in this manner.

3 If desired, change the precedence order of the DNS servers in the Current DNS Server Address Order area by dragging a DNS server IP address.

The system connects to the DNS servers for name resolution in this order, starting with the address at the top.

4 Enter the domain for your environment in the DNS Domain field and click Add.

Multiple domain names can be added in this manner.

This allows short names on the network to be resolved with the provided domain name. If this information is not provided, all computer name resolution is performed using the fully qualified domain name (for example, computer.domain.com).

5 If desired, change the precedence order of the domain names in the Current DNS Domain Order area by dragging a domain name.

This is the order in which the system will try to resolve the short and fully- qualified domain names.
