KVM Backups - DO NOT USE

@KOOLER said in KVM Backups:
Aren't there any agent-less KVM backups available? Anything like Veeam?
None that I know of. Scale does an agentless backup but you have to have a Scale cluster, not just KVM.

I was under impression they license somebody's else technology, don't they?

For their basic backup, no it's all internal. For more advanced features they work with third parties but don't license it, it's sold separately.

Do you use their agentless backup? How do you find it against say Unitrends or Veeam? thanks!

It's very basic. Just full images and automated exports. Nothing extensive. But for firms needing a basic, free backup mechanism, it gets them that. In most cases you would still want something more robust, like StorageCraft, Unitrends or the like. A Veeam product for it would be awesome. But it is enough to get automated data protection in place.

Qemu has some kind of incremental backup, but I haven't investigated much.
I just want to point out that one advantage to exporting to a raw .img file is that you can mount the image and pull files directly. If you need to import, just have qemu convert the .img back to a .qcow2 file and use the XML dump to rebuild the VM.

Is the move away from an agent based backup really worth that much?
Didn't we have this conversation a few months ago?

Unlike a lot of people, I'm fine with agent based. It might not be ideal, but it isn't bad. The big move here, though, is to "free and included."

I gotcha... So there is a free and included one in KVM, but no Xen or XS right?

There is a free, included one in Scale and one in XO.

Remember, KVM and Xen are base products. They "include nothing" because it would be foolish for anything to exist there. The idea that everything should be built in monolithically is a Windows one. That doesn't make it wrong, it is just one approach and idealistically opposed to all product markets except for Windows. One of the things that the Vmware crowd brags about is how little ESXi does (seriously, they do this.)
Xen and KVM actually do... nothing. It's their support environments that do everything. For Scale, it's the Scale system, not KVM, that does all of the features. With Xen a lot of features come from XenServer and a lot more come from Xen Orchestra. But those things are part of the ecosystem that you get for free. So it kind of feels like they are included, but really they are layered on top, as they should be.
Just like Xen doesn't include DRBD or Gluster or CEPH, but Xen's ecosystem always includes them.

You're right.. I have to keep reminding myself of that. But SMB's don't want to be chasing down dozens of little pieces all over the place to make these pieces work.
It's one thing or a larger company to have a team who's job it is to do just that - Scott's been talking about using Xen for decade plus. I have to assume that Scott the one man who is equal to nearly 10 normal mortals, has managed to collect and put together all of those parts.
The simplicity of XS and XO are what really give Xen any teeth in the SMB market, a la Windows style, everything in one place.
The bad thing about these groupings though, as we found out with the use of VHDs in XS, are the limitations those packages place upon us.

It's hardly chasing down lots of pieces. It's XenServer + Xen Orchestra on one side. Or just Scale on the other.
Compare that to VMware. You need VMware, Starwind, Veeam and how many more components to add up to just one or two in the KVM or Xen worlds? And licensing is the equivalent to many pieces, at least in terms of tracking down and complexity.
Hyper-V isn't quite as bad, but similar. You have Hyper-V confusion, tools for managing Hyper-V, Veeam, Starwind, etc.
The open sources pieces, even though they are separate, are normally bundled more completely than the VMware and Microsoft equivalents.

That's not what I meant.. I mean Xen.. then going and finding all of the other things you need to go along with Xen.

Here is where I was giving props to XS and XO for bundling things together to make it easier.

But you don't. Just like you don't get ESXi without vSphere. You don't get Xen alone. That's silly.
That's like saying that you went and got the NT kernel and boy is it complicated to build your own windows OS around it. No, you get Windows which is the NT kernel and all the other stuff packaged together.

But if you want a Xen solution today that supports VMs with image files larger than 2 TB, you can't use XS, and therefore can't use XO either.. so what is your option then?
Sure you can bandaid it with spanning, but come on, should that really be required?

Have less data.
(JOKE.)
