a full power down of the VM
Which isn't out of the question... not really. Does this database need to be up 100% of the time?

Not 100% of the time. No.
But equally, daily downtime just for purposes of a backup is too frequent, even if only a few minutes. Its something we can plan for and will find a way. May be the case of just using the built in backup tool, and having documented rebuild process should the VM fail.

No. But kinda silly.

There is no reasonable way, and no reasonable reason, to avoid the built in tool. If you want a traditional backup model, just use the native tool to make a local backup, then backup then VM as you are now. Its unnecessarily heavy. But it will work.

This is probably the way to go. Even building a template/cold spare to spin a clone up when/if something goes wrong may be a good idea. Then you just restore the data to it and you're good to go. No nearly as automated as the Devops approach but feasible for someone without that experience to just load up.

You all need to learn to just ignore Scott when he takes his shiny toy and runs with it.

@Jimmy9008 I stopped reading early on because Scott.
Did you actually ever try to make and restore a backup from the hypervisor with Veeam?
A hypervisor level snapshot is not the same thing as guest backup. it is different tools at a different layer.
It may or may not work with your application, but it is a totally different mechanism.
While state solutions may be nice, they are by no means the bbest solution @scottalanmiller always makes them out to be. It add complexity and requires a total change of the design of your IT infrastructure.
Shit is not, ever, as black and white and Scott tries to make it.

Actually they are the same mechanism here. Its an LVM, just one layer down. Otherwise identical. I know you love hypervisor backups but they arent magic and within this context they work identically.
Dont give false hope. If you know how hypervisor backups work you know that they cant solve this problem.

The shiny toy here is pushing hypervisor backups blindly.

Actually it is black and white. You are pretending it isnt to push your darling product that you always push without looking into what his issue is or understanding how the LVM layer issue is identical between solutions.

Hi Folks,
I have used the free Windows Veeam backup tool for a while, love it. Works perfectly. We have a Linux machine (CentOS 7) which needs to be backed up regularly, so I have turned to the Linux Veeam tool (I expect it would be just as good as the tool for Windows).
Installed, updated, and setup to backup to our NAS. Backup ran successfully. I am able to restore the backup using the recovery disk from Veeam and the backup file from my NAS. Seems smooth... the problem though, the software on the Linux server (DGraph) stops working when restored from the backup.
The machine boots fine, I can access the desktop, but when trying to run DGraph I get errors. I expect the application isnt happy about being backed up by Veeam when on, so I tested some more.
I reinstalled DGraph and got it working again. Then, I ended the DGraph process (or service - whatever its called in Linux?)... then I ran the backup. I guess if the application is offline when the backup is made, the backup must work fine. But upon restore DGraph still does not work.
Not sure what is going on, even with DGraph off before the backup the application fails. Any ideas?
In Windows, if the software isnt running I have always seen a backup work successfully. Not posted on to Veeam forums yet, wanted to see if any ideas from here.
Any other tools I should try other than Veeam?
Best,
JimIf I read correctly, I understand you're using a Hyper-V host running a CentOS 7 VM that has DGraph installed.
I wouldn't put any backup software on the CentOS 7 VM. I'm saying this, first, because I don't know what DGraph is, and second, there are reasons to put backup software on VMs, but I don't see a reason to in your post.
I would back up the VM through the Hyper-V host using Windows Server Backup. For a smaller number of VMs, this works very well as far as backup process and restores. It's pretty simple and just works. In one example, I've used it in production on a Hyper-V Server 2016 host for up to about 60 VMs totalling roughly 15 TB back then, before I was sure WSB was way out-grown.
The free Veeam you are using in your Windows VMs will not back up VMs via the host... meaning you cannot install the free Veeam edition on your Hyper-V host and expect it to back up your VMs.
Host-level backups of your VMs will fully take advantage of the VSS capabilities in Hyper-V. Also, in your CentOS 7 VM, be sure to install the hyperv-daemons package:
sudo yum install hyperv-daemons

@Obsolesce you already know from this thread that that doesnt solve the problem. You are just repeating the same issue that he was trying to resolve.
VSS causes this issue the same as any other LVM.
Read the thread. Weve beaten this to death. VSS isnt magic.
-
While Jared likes to pretend Im pushing agent backup, ive clearly nit recommended agent or agentless. Ive explained ad nauseum how they share a mechanism that doesnt work here and neither can work without a native backup.

I will have to read more. I posted after only really reading the OP.

Actually it absolutely does do this. You are limited to ad-hoc VeeamZIP creation, but it works perfectly.

His DB doesnt quiesce and he cant find processes to stop manually. So anything using an LVM whether a Linux agent or Hyper-V's LVM called VSS will be expected to corrupt sometimes. Even when not clustered. Becayse it is a DB, not a storage quiescence problem.

Perfectly but not with a database like this. Takes backups as well as the agent. Which is not good.

Actually, no. You have no idea if this is true. Veeam absolutely can (and should when configured right) use the native guest tools. But it doe snot require it. Making a snapshot form the host has no requirement that the guest OS even do anything.
I also was not pushing hypervisor level as the solutoin. I was asking if it was tried or not.

You have no idea if that is the case or not as it was never attempted to our knowledge.
