Proxmox 5.3 install and backup

[nicolas studiokgb]

Hello

I'm looking in a simple way to backup the proxmox system HDD of the machine.
It's a multi network (5) with vlan and so. if the system hdd crashes I have one hour reconfiguring a new install from scratch.

I'm not talking about the VM which can be backed up in proxmox but proxmox install itself.

I've tried Clonezilla disk to disk . works but very long (LVM has to be cloned in raw so 300gb is 1hour...)
I can do clonezilla networked... a bit complex just to do a simple backup...

Is it possible to create a unattended Usb Stick with all the config already set up ? (put the usb stck in the machine, boot, install, connect and restore all my vms from a network cluster (eg) easy as my node config is already set up.

Any idea ?

Thank you

Nicolas

Backing up /var/lib/pve-cluster/config.db basically backups all configuration, including firewall rules, users and perms.
For network configuration, backup /etc/network/interfaces separately, because I am not sure whether Proxmox restores it from the db.
