Upgrading Raid controller in Dell R710

[Dayve]

I'm going to upgrade the raid controller in my dell r710 from a perc 6/i to a h700.

I have searched around and found it is recommended to have a backup of all CT's, VM's and data. What is the best way to do that on Proxmox?

Should i setup a second proxmox and do a cluster to migrate everything? (Still have a old proxmox server that I could fire back up)

Both (Old and new servers) are running version 6.1-5

Also: Is there a way to backup promox its self. or do i need to do that?

HI,
you can directly use PVE to backup CTs/VMs, see https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_vzdump.
Backups can for example be placed on a remote storage (e.g. a cifs share) or usb disk.

Setting up a second node can be of interest if you wish to keep everything up and running while you perform maintenance work on one of the nodes (although if you are interested in clustering you should go for at least 3 nodes or 2 nodes + quorum device, see https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_corosync_external_vote_support and in general https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_pvecm).
If you wish to use live-migration, you will have to use a shared storage, see https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_storage

To perform a backup of PVE itself, you will have to at least backup the config files https://forum.proxmox.com/threads/best-practice-for-proxmox-self-backup.38382/page-3

Hope this helps!
