Proxmox 8.4 soon EOL, Do i NEED Px Backup Server?

[nadirian]

Hello, first time post, I hope im at the same spot, and that my question hasnt been asked before .

So i got an message about 8.4 being EOL soon, and that i should upgrade soon.
So i read the guide, which suggests a "Co-installed Proxmox Backup Server". I understand that i need backups, which i do on a separate machine.
Every sunday i take a snapshot of the vms i have.

Anyway, do i need to get a backup server? I dont have a second machine available, i only do some selfhosting at home.
I installed my proxmox using the proxmox iso, so there "should be no issues" as ive understood..
I for sure can yolo everything and upgrade, but Id rather be "as safe as possible". But i do not have the possibility to setup a backup server.

Welcome, @nadirian

Every sunday i take a snapshot of the vms i have.

A snapshot is not a backup.
I.e., a snapshot is not sufficient to save data. If you need your data, you must have backups.

Anyway, do i need to get a backup server?

There are more than one way to create backups. Proxmox Backup Server is one of them and it's a good solution.

I dont have a second machine available,

Ideally, Proxmox Backup Server is a separate physical machine. But it can also be installed in the same physical machine in which Proxmox Virtual Environment is installed. Inside PVE or as one of the virtual machines in this PVE.

I installed my proxmox using the proxmox iso, so there "should be no issues" as ive understood..

Sh*t happens ;-).

I for sure can yolo everything and upgrade, but Id rather be "as safe as possible".

That's the approach I like .

But i do not have the possibility to setup a backup server.

You do have, probably. Not necessarily as a separate physical machine.
A disk (internal or external) which isn't used by PVE is needed.
And a piece of software.

So i read the guide, which suggests a "Co-installed Proxmox Backup Server".

Do you mean this?:

Prerequisites

• Co-installed Proxmox Backup Server: see the Proxmox Backup Server 3 to 4 upgrade how-to

https://pve.proxmox.com/wiki/Upgrade_from_8_to_9#Prerequisites

This only means, that if you have the PBS co-installed, you should read the upgrade guide for it too...

Hello, and thank you so much!

I tried to read up on PBS yesterday... I couldnt quite figure out if "This is a full blown enterprise large system" or if its simply "Run this in docker and point to a NFS-share and youre good to go!" ...
Also, the VMs and LXCs i have, its not the end of the world if they go corrupt, but it would make my home network happier if they didnt (the people in my home )

And yes, shit happens. So thats why i hopped on to this forum to check a few stuffs .

I got a few more warns and fails on the pve8to9-script,

WARN: Removable bootloader found at '/boot/efi/EFI/BOOT/BOOTX64.efi', but GRUB packages not set up to update it!
Run the following command:
echo 'grub-efi-amd64 grub2/force_efi_extra_removable boolean true' | debconf-set-selections -v -u
Then reinstall GRUB with 'apt install --reinstall grub-efi-amd64'
FAIL: systemd-boot meta-package installed. This will cause problems on upgrades of other boot-related packages. Remove 'systemd-boot' See https://pve.proxmox.com/wiki/Upgrade_from_8_to_9#sd-boot-warning for more information.

First, i take it that the GRUB-command is tried and evaluated? So i mean, its safe to run? Sadly, i do not understand really what it means, the error.
Second, I surely can remove the systemd-boot package, but how do i check if i use it or not? I tried consulting google and LLM to figure it out, i believe i do not use systemd-boot, but, better safe than sorry?

NOTICE: Starting with PVE 9, autoactivation will be disabled for new LVM/LVM-thin guest volumes. This system has some volumes that still have autoactivation enabled. All volumes with autoactivations reside on local storage, where this normally does not cause any issues.
You can run the following command to disable autoactivation for existing LVM/LVM-thin guest volumes:

    /usr/share/pve-manager/migrations/pve-lvm-disable-autoactivation

Is this also, safe to run?

Thank you so much for taking your time to answer me !

Ah yes, i meant that! Yeah, of course, staying up 2 date is quite important

Both, sort of ;-). I don't know if literally in docker, but in a VM is definitely possible.

I can't reliably answer those questions, sorry.
First read carefully https://pve.proxmox.com/wiki/Upgrade_from_8_to_9

If you can't find answers there, search this Forum for the particular error and warning messages - there are quite many posts with questions (and answers) dealing with doubts during the upgrade.

If you really can't find the solution, you can start another thread. (Don't mix issues in the existing thread ).

Alright, thank you so much for your time! I have a PBS in LXC right now, trying to figure out how to share my /dev/sdb (that is on my proxmox ve) to the PBS (its a separated disk, used for the snapshot dumps that i have)
