I am thinking of building a new PVE server that may be used for some tasks plus be like a backup server in case of disaster.

My question is, say I have it -- Can I restore a VM backup to it?

What steps will I have to take?

TIA
 
Can I restore a VM backup to it?
Sure, that pretty unproblematic and a good idea. I would recommend to set up your new server with the same bridges and storageIDs. And for the VMs a CPU type that fits both hosts. And in case you want to cluster them, for migration and synced IP sets/firewall rules/aliases and so on a small third machine as a qdevice would be a good idea.

Thx for the reply. I use now intel nuc and plan to bu more powerful one.

How practically can I setup same bridges etc.? In other words, I need to create a clone of my existing server. Maybe after setup restore all system files (/etc/*)?
 
Just use the same interface names for the bridges. If you for example use vmbr0 for VMs/LXCs and vmbr1 for management then do the same on the second server. Not that important for the bridges as you could restore the VMs and then edit the vNICs before starting them if you don't plan to run a HA cluster. More important for the StorageIDs, especially when making use of multiple storages for a VM, as right now PVE won't allow you to select which vDisk should be restored to which storage. You can either restore all vDisks to the same storage you select or you don'T select a storage and it will restore them to the same storageID they were on when the backup was done. So only way to restore vDisks to multiple storages is to have the same storageIDs.

Ok I hear you cool
May ping later for details when I get a new box

But it’s very helpful now

BTW any videos of these specifics you know of?
