@Dashrender but you don't need XO at all, it's just a really great solution to have in addition.
Sure - and you don't need any of the backup solutions for the rest either. Not sure where you're going?

Think of Virsh (the CLI as XAPI) or Virt Manager like XenCenter. These are things you need to either use or learn to manage the hypervisor.
So stating "I need something additional" is the red herring as it makes it sound like something entirely separate from the tools and management approach is somehow not needed with KVM.
When it still is there. It's just automatically installed.

My post was strictly about backups. Can you do backups using only XAPI? or only Virsh?

Yes.
No. You make snapshots and such. but then have to export and move and copy to make them a "backup"

Yes, you are correct, this I didn't mention.
But this is still doable through the command line.
Edit: but almost no one is really doing, this. At least none that I can find.

Would you still use it without Xen Orchestra?
I asked because I feel Xen Orchestra has a big part in making an individual to use XenServer/XCP-ng.I would definitely not use XCP-ng without XO. I would probably use Hyper-V and Veeam otherwise.
I want to try KVM, but I don't have time to figure out the backup stuff right now. Maybe it's time I switch my home lab over to KVM.
Before all the changes with XenServer, I had no problem using XenServer with XenCenter for what I needed. I actually like how quick I got use to using it and the cli compare to my first experience with Hyper-V and KVM.
Backups are always hot-topic with hypervisors. I don't really have issue using Agentless or agent-based backups.
I think tossing backups into this conversation at all is a red herring to use Scott's term. It has nothing to do with the questions at hand. In the case of XCP-NG you need XO/XOA, in the case of KVM - you need???
KVM actually can do backups, even with rudimentary CBT, with only the built in command line tools. But it's a pain. But it is there.

Technically you can backup to a remote using XAPI and export that without touching anything else besides the command line. I was doing it via script before I found XO some time ago and while it worked. It was less than an ideal approach for the organization.

So yes - backups can be done - but it's a huge PITA using those native tools.
got it. -

When snapping to a remote location How bad did that hit the disk? I'm guessing pretty bad.

Why would you guess that it would be bad?

It was never an issue as the backups were completed after the office had closed for the evening. But they took less than an hour to complete. Total.

umm like how? Snap's don't do anything to the disk after the initial writes to create the new snap files. Then it is just read of the snap to the target. This is zero different than every hypervisor backup mechanism ever.

Cockpit is there by default, no effort there.
Only if you installed Fedora Server Edition.

It is not there by default if you choose a minimal install. But that was not the point of this post.

I have to dig more into this - by simply choosing the option Scott pointed out - I now have a machine that's logged in - but no clue what to do next? in XS or VMWare or Hyper-V I'd be presented with a graphical display telling me to download something from some IP address (well OK not Hyper-V), and install XC or VMWare whatever it's called - or I think starting with 6.5 visit the webpage built into the hypervisor now, etc... but with KVM - nope, just a fedora prompt and me now going to search for 'what next'.
