Nextcloud scenario
-
A friend has a small datacenter with the normal bells and whistles. We had a discussion where he would provide the rack space and a public IP etc. I provide a server and each of us a Nextcloud instance. No cost to us and I have physical access to the hardware. My go-to is Hyper-V 2016 and a NC VM. I thought about trying KVM (Fedora) and Fedora for the NC instances but there has been so much fuss on here lately about lack of backup options for KVM. My NC is on Vultr now as well as a few local installs. What do you guys and gals think of this scenario?

@brandon220 Until you're comfortable writing your own scripts to get backups done in KVM, stick with what you know.
KVM backups are conceptually very simple, but I've not found a good set of scripts for it yet.
Process:- Create an external snapshot
- Backup the .qcow2 main file using your normal backup tool
- Remove the external snapshot
I'm not super good with sed or awk, so I have issues getting a script that automatically backs up all KVM guests without having to enter each guest by name :frowning_face:
-
I think ultimately you should choose the Type-1 Hypervisor that you have the most experience with @brandon220. Both Hyper-V and KVM are good options.
-
@travisdh1 conceptually though this shouldn't be a difficult thing. It should already exist.
How many places are only wanting to backup a single VM at a time?
-
Now as a part of a separate conversation you may offer backup services for a few dollars a month and then need a script that allows granular control.
But even Xen Orchestra has this control and you don't need to be typing away creating a script from literally nothing to do this. It's "built in" to XAPI and Xen Orchestra simply uses the API calls to do the job.

There are scripts available for a propery configured system. My home lab box is not a properly configured system tho, and I had little choice in this particular matter (no LVM on OS install, FFS).
How many places are only wanting to backup a single VM at a time?
Considering that my home lab currently has 11 guests running, nobody.

You've got me beat. I only have 8 right now

Honestly, I've not used KVM but thought this would be a great learning exercise. Been using Hyper-V for years. I prefer it over VMWare and Xen.

@wirestyle22 I could do everything I need on this host with Powershell. I hate Hyper-V Manager on non-domain joined hosts. More trouble than it is worth IMO. I miss 5-Nine being free.
-
On a side note it looks like @olivier appears to have a way of avoiding upgrading and loosing the functionality as mentioned in 7.3
-
Ignore everything @travisdh1 says about backups because he has no idea what he is talking about.
Of course it is easy to make a backup of a qcow2 and dump the VM confit to a XML file, it is 4 lines of code, but that doesn’t have dick to do with a good backup solution.
-
Is NC even something you want to back up in this manner? Why not back up from inside of the file system?

Exactly. Nice and easy without imaging anything.

And with the help of salt or ansible to deploy Nextcloud, it’s even better.
