I`ll have tu upgrade server`s array from sas to ssd, so I`d like to backup and restore node OS smartly.
I have to create a new array in raid controller because there is no another way.
How can backup and restore node OS smartly?
I know, I can make fresh install and then replace /var/lib/pve-cluster/config.db and /etc/...this is simple way but not so smartly as I can Image.
Is there more intelligent option?
 
Maybe a block level backup of your system disk while booting from a USB stick? Clonezilla might be an option.
 
Of course using boot media (some linux) and dd with tar and restore it from another disk/array is a way too.
But we have 2022...there is no better way in this year?
I`v been using dd for backup 20 years ago and I hoped we have some newer, smarter solution.
 
Node backups are on the roadmap but until now there is no easy way to backup and restore a PVE node.
 
I was searching for this, backup a host is still in the roadmap, so I think this proxmox wiki link has the best solution, check it please, according to this, we need to backup
/var/lib/pve-cluster/ /root/.ssh/ /etc/corosync/ /etc/hosts/ /etc/network/interfaces
because according to proxmox formum link /etc/pve is a virtual filesystem living in a sqlite3 database '/var/lib/pve-cluster/config.db'

but according to proxmox wiki link
Back up all files in /etc. You will need various files in /etc/pve, as well as /etc/passwd, /etc/network/interfaces, /etc/resolv.conf and others, depending on what is configured by default. (/etc/pve has the file /etc/pve/storage.cfg wich will re-map and make available any external media you used for backup)
Click to expand...
So I think we need all /etc and /root/.ssh/ and custom files and folders, and as a precaution also /var/lib/pve-cluster/.
If someone has something clearer, please comment, there is no clear way, I hope I don't have to make the restauration.
