Convert disk images saved as templates

[laniatus]

Greetings,

I am trying to use disk images saved under /var/lib/vz/templates on our Proxmox server in virtual machines.
They are disk images that contain very valuable and important data, but the previous CTO converted them into templates without any extension.
How can I make these disk images usable in my virtual machines or how can I access the content of these disk images and backup my data?

I am very sure that these are disk images, I need your help to convert them to disks. Please feel free to elaborate as I am a bit of a novice, I have not used Proxmox at an expert level before.

Thank you,

The usual way, when a VM or CT has been converted to a template, is to clone a template to a new VM or create a new CT based on the template.

Hello and thank you for your response and your precious time. Can you tell me how I can do these steps? The files available here do not have any extension (.raw, qcow2 etc), I really don't know how to use them.

I'm not sure. You talked about them being unintentionally being converted to templates. Does they show up as VM or CT templates on your Proxmox web GUI? Then just select More > Clone from the Proxmox web GUI to create new VM or CT identical to the template. That's the usual way to undo a accidental conversion to a template ( by create a new guest based on the template).

I think they are templates because they are in a folder called Template. I'm not sure about this, the CTO before me created such a structure before he left, I'm trying to figure it out. The files here are files without any extension, ranging in size from 300/600GB to 3TB. It's probably a disk image, but I'm trying to make it usable in VMs. Honestly, I've been trying for 2 weeks, the last resort was to ask here. The files I am trying to convert to VM are the ones starting with W0, I think they are Windows server backups, I am looking for a way to access the data contained in these files.

I'm trying to convert it to raw now. I will try this but if there is another way please feel free to tell me ^^

I'm sorry but I don't really understand what happened, but would it not be much easier to restore from backups?

I would start by doing: file [filename]
This should give you an idea of what those files are, hopefully.

good luck
