Hello everyone. I'm new in Linux and in Proxmox at all. I have Linux Debian Proxmox server with VMs on it. I decided to install a couple of software to node for inventarisation and monitoring (OCS Inventory aggent and Zabbix). My question is: Should I make a backup of server before install this software and if I shold, what directories I need to backup to save data of node?

You should always have a recent backup of your guests (Vzdump or PBS).
And in case you want to backup your hosts configuration too you should backup the complete /etc folder (especially /etc/pve) on a regular basis using your backup tool of your choice (for example using the proxmox-backup-client if you got a PBS running).

And if you dont want to reinstall PVE on a failure you can also use proxmox-backup-client or clonezilla on a bootable USB stick to create a blocklevel backup of your complete system disk to be able to restore a 1-to-1 copy of your complete debian/PVE.
