Proxmox Checkscript

[Skyministrator]

Hello everyone.

I created a bash script, that checks for QEMU VMs the (non-)existing backups from PBS.
This script is useful, if:

• multiple users (customers) uses your PVE
• you own multiple PBS and want to verify retention
• verify data privacy

Example, why this script is useful:

1. Customer A deletes a VM with 3 backups
2. couple days later, Customer B creates VM and gets same VMID --> possible to restore VM from customer A

This script doesn't solve this, but encounter it with notification to admins, so they can clean everything up.

My Script is on github, so if you don't mind, i would like to have feedback.

Shouldn't dedicated namespaces or datastores for each customer avoid such issues? Nontheless I think such a Script can be useful to detect issues but it would be more useful if it would output the data in a Format suitable for parsing through a monitoing tool e.g. a nagios/icinga plugin or a Prometheus exporter

Haven't tested it yet, but will do

Hi
I would like to try this but I run Proxmox stand alone not in a cluster. Is there a way to do this?

Thanks

Thanks for the response.
To your question:

It depends.
With a larger number of customers/users, it can be difficult to manage the maintenance, even if it's monitored with ncpa, snmp etc..

For example: 1 Cluster with 15 Nodes. 2 PBS, each PBS with only 1 Datastore .
In this one Cluster, 200 customers are working. Some have their own software systems that interact with the Proxmox API, while others access the web UI directly.

But i can relate your point.
In my position: If an existing infrastructure is proven to be effective, i only can work with what i have.

Your Node is already a "cluster" on a normal PVE Installation. You can use this script.
Just check API Connection for the "Cluster" and for the PBS. The cluster get's information about all VMs, Node indipendent.

Glad to hear that.
I await your response to your tests and thanks for testing it.
