Any way to add/remove a VM ID to /etc/cron.d/vzdump through CLI?

[Tuxington]

Hello,

I'm trying to figure out if there's a CLI command that will allow me to edit /etc/cron.d/vzdump at will, without use of the GUI?

Is there anything in place that will "reset" /etc/cron.d/vzdump automatically on Proxmox's end? I want to edit the line using ansible to add/remove VM's I create/destroy. Would editing it using ansible update the GUI as well?

I grabbed a HAR while editing the GUI and saw the put request info. Should this be done through the API?

Thanks

You should edit the /etc/pve/vzdump instead the /etc/cron.d/vzdump.
As long the syntax is correct Proxmox VE has no problem with it.

The API would be the safer way.

With Proxmox VE 6.0 you can add a whole pool as a backup target. You could leverage this by creating such a backup job and then just specify that pool on VM/CT create - it will then be included automatically in the backup as long as the VM/CT exists.

Thank you! i wasn't aware that that file existed. I probably glossed over it thinking the path was for cron.d. I will give it a shot using the API first, but I will admit it's not my strongest skill! I did see some documentation about the API though, so it may not be as bad as I'm making it out to be in my head.

Sadly I'm still running 5.4. I didn't realize there was an upgrade, so I will have to plan that. My setup also isn't that complicated, I just have a couple of VM's(and possibly more in the future) that I don't need backed up, and prefer to maintain a curated list. I will have to look into that feature though once I hit 6.0 as that sounds way easier to reach my end result.

Thank you both very much!

So after upgrading to 6.0 I found the "Exclude Selected VMs" backup option. Works for my situation! Not sure if this was a new(ish) feature that I never learned about or didn't even think about it when I initially setup my backups however long ago.

Leaving a note about this in case someone else stumbles across this post with a similar idea to what I had, but may not actually need to create a more complicated solution.
