Kinda, they have an appliance (prepackaged ova exported from ESXi), I was going to test it.
Crash consistent only, I'd not use that. Why are you looking at it?
Why am I looking at the application?
Yes, why are you looking at a crash-consistent "backup" tool?
Not too many other choices out there!
What do you mean? There are endless awesome choices. This just isn't one of them. Why do you perceive a shortage of backup options?

List them out for me, please

Crash Consistent is the issue here, that I would see. When there are "real" backups that are full, rather than non-quiesced, why bother taking a backup if it isn't reliable? Reliability is the biggest factor in whether you consider a backup useful. It's not like you could use this and tell a client that you took a backup.

In bold are the four that I would find most interesting and would only very rarely consider anything further. They range from free to pricy, self supported to enterprise support, and cover basically any possible scenario. Beyond those, I've had a lot of good luck with Netbackup in the enterprise.

Should have said, I prefer agentless!!

@FATeknollogee said in Virt-manager: IDE disks:

Which, in this case is the same as saying "I prefer it not to work."
Agentless isn't an option here, period. Beyond that, why you have a "preference" for this kind of thing is an additional problem. IT should not have preferences, we should want proper solutions, however they work. Desiring a specific way of doing it, that can't be done, is an emotional mismatch.

I hear you loud & clear, but, I still prefer agentless.

Since KVM doesn't support working agentless today (outside of very specialty systems like Scale HC3), you are at a starting point of having eliminated all working backups and only looking at a category that doesn't work. So naturally it will feel like your choices are limited, because there are literally zero.
But this should not make you feel that the choices are limited, the proper reaction is to step back and say "I'm doing something wrong, I'm not looking at the goal (to protect the servers), I'm stuck in the weeds of an emotional "want" rather than a business "need"."

@FATeknollogee said in Virt-manager: IDE disks:

Right. So you've identified the problem - an emotional breakage. You have to fix that, period. It's not a viable reaction. You need to step back and figure out why an emotion is driving you rather than reason and goal orientation.
Everyone has their emotions and preferences, but there is no place in IT for those emotions to creep into our decision making. None. The moment we've done that, we move from being IT pros into being purchases in a consumer process.
So in IT, one of our most important skills is learning to set the emotional preferences aside and focus rationally on goals and logical decision making.

I love the idea of agentless, it's great. But it's only an idea in this case. And one that honestly, isn't important at all. Sure, conceptually it is neat, but that's all that it is. From a business or technical perspective, it's just a pointless thing that only sounds cool because we improperly use the term "agentless" even though there is an agent. Even the title of the category is engineered to invoke an emotional reaction, and it works.
-
So, now that you know that there isn't an option for a working agentless backup for KVM... do you want to go with a non-working backup system that you can't claim to really be a backup, or do you want to pursue something that can actually take what is considered a backup by the industry to protect the workloads? What is the end goal that you are trying to achieve?
I realize that in a lab, playing with anything is fun. But this would be considered a waste of resources to focus on something that conceptually can't be deployed in any real world scenario.

You said Scale was the only one that had KVM "agentless"?

@FATeknollogee said in Virt-manager: IDE disks:
This is for Nova only, from their website AFAICT. So doesn't apply to KVM. It requires an entire custom storage layer, and then can talk to the hypervisor.
That's no different from Scale HC3.

That works. HYCU requires that you replace KVM, as does Scale. Yes what they use is based on KVM, but it isn't just KVM. It's a custom new product made from KVM.
And vProtect doesn't take working backups (they state it at least half a dozen times on their site just from a casual look.)
Trilio can work only with OpenStack and only using Nova and beyond that, I've not researched if it can still work with just KVM.
The point being, none of these come close to meeting the criteria of being able to take a backup of KVM's VMs themselves. They all require either KVM to be replaced, or a storage layer that they use so that direct KVM would fail, or don't make working backups.

Interesting, maybe they've done enough work to make it work. It would be awesome if someone had done this, but vProtect is extremely open that they have not.
Has anyone looked into Trilio enough to know if their backups are safe?
