How to backup the hypervisor (pve)

[tkn-teamf]

Hi forum,

I can backup VMs, containers, ... but how do I backup the proxmox ve instance itself?

TIA, Thomas

Hello,

if you mean the pve configuration, simply backup the /etc/ directory and especially the /etc/pve/ directory.

Is there a documentation how to backup and restore the hypervisor?

Yes you could use the proxmox-backup-client to backup your data or your preferred backup-tool (e.g. rsync)

Important files/dirs to backup are:

/etc/hostname
/etc/hosts
/etc/network/interfaces
/etc/vzdump.conf
/etc/pve/

Thanks for the quick reply, are there any restore steps ? Or can I overwrite it once a fresh install is done?

Yes, but please think carefully about what you overwrite.

For example: If you are using a cluster /etc/pve gets restored by the other nodes.
In that case do not restore /etc/pve, you could overwrite changes made by the other nodes
