Hello all,
I have a single VM on Azure. I manually update the server monthly. When it reboots to install the updates, the service will not be available. Are there any suggestions you can give me to avoid downtime for my monthly maintenance?
Regards
ET

I suggest you to run your service at least on 2 VM's to keep the service available during one VM maintenance.
Installing updates very important, If you are running Server 2019 Gen2 you can opt-out of a HOT PATCH option which reduces the reboot occurrences during the installation of patches.
Thanks for your response.
That is the problem I dont know how to have SFTP service on 2 VM .

Hi @ET , Thanks for posting your query here!
You can actually schedule a restart by referring to the document Manage device restarts after updates based on the downtime.
Kindly let us know if the above helps or you need further assistance on this issue.

Thanks for the document.
Actually I am looking for a solution to reboot my server without needing a down time. Because this VM should be always available.
You can't have a 'single' VM highly available - it's simply not possible. You must create at LEAST a 2 node cluster for failover or mechanism to bring high availability. In a 2 cluster node, you could restart one server, as the other takes over while the first one is restarting, then they sync up, and then you can restart the 2nd server while the newly restarted server takes over.
You also need to look at all the other components - storage of data, services (in your case, SFTP) and see how to configure these for HA. a 2 node cluster both with SFTP enabled sharing the same storage location - which also has it's HA abilities (so probably another 2 node cluster for disk storage).
@ET , Please let me know us the above-given solution helped.

Hello,
Thanks for your response,
Is there any document available in Azure for having one storage as a disk for 2 VMs?
