Question about Backup Proxmox Hosts

[debi@n]

Hi, i read the documentation about the procedure. but i have a question about..

Caution
Please note that the proxmox-backup-client does not automatically include mount points.
 Instead, you will see a short skip mount point notice for each of them.
 The idea is to create a separate file archive for each mounted disk. 
You can explicitly include them using the --include-dev option (i.e. --include-dev /boot/efi). You can use this option multiple times
 for each mount point that should be included.

When i do the back up about proxmox VE i can see that some " skipping mount point", should i include every directory with the option --include-dev ?
i want a full backup about the system in case of disaster i can restore it.

Output:
skipping mount point: "dev"
skipping mount point: "etc/pve"
skipping mount point: "proc"
skipping mount point: "run"
skipping mount point: "sys"
skipping mount point: "var/lib/lxcfs"

Cheers

Those are "virtual" file systems - there is no need to backup those things.

Sorry for bringing this one back from the death. But I am currently preparing for my upgrade to PVE 8.0 and one requirement as stated in https://pve.proxmox.com/wiki/Upgrade_from_7_to_8 is to backup all files in /etc/pve.
Now I just realized that my host backup has skipped /etc/pve ever since I set it up, and according to this post this is by design. Given this, how do I get to /etc/pve if ever I need the files?

Include /etc/pve in your backups or backup the config.db, as the content of the /etc/pve folder is basically stored in that DB. See: https://pve.proxmox.com/wiki/Proxmox_Cluster_File_System_(pmxcfs)

Great, that makes sense. /var/lib/pve-cluster/config.db is the file in question, right?
Given that my db is small, I will add /etc/pve so it's easier to get to individual files.

Thank you for your prompt response!
