Clonezilla is my go to for doing that. I have a tutorial where I should how to migrate from Virtualbox to XCP-NG here:

@olivierlambert

I work with enterprise companies and they NEED those reminders to let them know they should be using the supported version. I don't really see them as annoying at all.

@bullerwins

It's a wonderful feature, you can have customized filters for VM, storage, Templates, and Pools. Combine that with using lots of tags and it makes larger deployments very manageable.

@CodeMercenary

Under the xo-vm-backups directory is a series of directories named with UUID's that contain everything that belongs to a particular VM's backup. As long as you keep each directory and all the contents nested within it you will be able to restore that VM.

@jasonnix

That is enough to get it working and fine for most homelab environments.

@MichaelCropper
I recently did a video tutorial on how XCP-NG virtual machine dynamic memory management and over allocation works.

@starmood For each VM backup run inside of Xen Orchestra it backs up not just the VHD but everything that is needed to restore that VM to any other XCP-ng host. So in a complete loss situation you can load a new XCP-ng Host, setup Xen Orchestra, point the new Xen Orchestra to those backups and restore any of the VM's with all their settings.

The metadata backup of XCP-ng is just that, the metadata of the system and it's not granular. It's good to have because all the things like network setting and what VM's are on the hosts will be there, but the VM backups to me are the most important.

I have a tutorial covering how the backups work, it's from a bit over a year ago and there are EVEN MORE features now and I will be doing a new video this year to cover that.

I also have a tutorial on how you can also automate the backup validation process

If the storage type you have the VM is thick provisioned it will take up more space. Use a thin provisioned storage for better storage efficiency

If you choose 2 storage destinations it will copy to each of them at the same time.

@McHenry

I have a video breaking down how XCP-ng and XO work and at the 14:50 mark in my video here I break down how the XO Proxy works.

@nikade
Something to consider is that due to the way XCP-ng isolates for each disk for each VM for better security there can be some performance issues. But because it's per VM (unless your use case is to only running a single VM) this is less of an issues as most people run many VM's.

@jsox79 said in storage configurations are pretty disjointed:

reinitializing the hba storage

Are you trying to share the HBA storage from one host to the others?

@aqua-calc

I can confirm that a Synology works well as a backup "Remote" but as @olivierlambert said more details are needed to help.

@Matteo
You can use a SAN shared storage that is thin provisioned such as NFS.

@DustinB said in Delta backup questions:

As a discrete backup that is saved to each location individually.

Yes, that is a more accurate statement.

Also, there is an option for doing Mirrored Backups:

@Lulina

The VM created for the health check is deleted after boot confirmation is achieved by seeing the Xen tools.

@abudef
I only did that in my video to make it easier to show how things work with XCP-ng hosts, I don't think the VM's would work inside the nested systems.
