If I snapshot a VM and copy the snapshot off somewhere else it's a backup.

Sure, agreed. But that's not what @scottalanmiller said.

@scottalanmiller said in Reconsidering ProxMox:

We do, shouldn't, but we do because customers don't want to pay for better backups.

I was referring to this ^ Snapshots are not a backup, just like RAID is not a backup.

@scottalanmiller said in Reconsidering ProxMox:

Yeah, just for some reason in that table it shows that you can't. My guess is that it is a typo, but I've not tested it so I can't confirm.

It's defiantly not a typo. I am the member of a proxmox user group, and someone just did a install with LVM and everything related to snapshots was grayed out. Then we figured out it was LVM and not LVM-thin. So regardless if it's "all the same" it matters to proxmox.

I am surprised NTG would take on a client like this. We sure wouldn't. The risk is too great. We just tell the client to take there business elsewhere. Maybe we are sending clients to you guys!

@scottalanmiller said in Reconsidering ProxMox:

You definitely can. We use that as the backing to our main backup tools on LVM.

Then your using LVM-thin. Maybe that's just a subset of LVM?

@stacksofplates You can't take snapshots on LVM. https://pve.proxmox.com/wiki/Storage

@scottalanmiller said in Reconsidering ProxMox:

LVM is what we use.

So you don't take snapshots?

Seems like ZFS needs a ton of RAM.

You have to configure it

@scottalanmiller said in Miscellaneous Tech News:

I have no reason to run unsafe valueless hobby systems.

Isn't that the same thing you said about Proxmox? Now you're the biggest Proxmox fan like your having a love affair with it or something. Maybe FreeNAS would be the same way.

@scottalanmiller What’s your storage configuration like?

I’ve been playing with it on ZFS Raid 1 mirror. Proxmox OS and VMs all on same mirror. Performance is “OK”. Not as good as MD with same setup though.

Wonder if it’s better to create separate Raid 1 ZFS pools. One for the Proxmox OS and one for the VMs.

Did you configure ZFS correctly? https://pve.proxmox.com/wiki/ZFS_on_Linux#_limit_zfs_memory_usage What drives are you using?
