You can check the Failover Solution here.
There will be 2 servers, one Active and one Passive. The Passive will keep monitoring the active server services and if there is an issue, Passive server will take over.

@TheodorosG_3CX Thank you very much for your reply. Is there no downtime between the Active and Passive servers?

@TheodorosG_3CX Thank you very much for your reply. Is there no downtime between the Active and Passive servers?

There is downtime - at least "Time interval between tests in seconds" + time it takes to start services + TTL of DNS update.

Beat me by 10 seconds.

I was going to add it’s not a direct failover/hot spare, the restore of the primary’s backup is scheduled.

Exactly as @SweetAction mentioned however this will not take long.
