Adding disks allready with data

[Camagur]

Hello community!

I'm having trouble to understand the concept of adding disks allready with data!
so the question is if for some reason it is necessary to reinstall proxmox, how do you add disks that already contain data without having to format?

Thanks

What is your use case where you want to access this data?

Depending on that the steps needed might be quite different.

ok! I usually install the proxmox on a 120gb SSD disk, then I have 2x500gb HDDs for ISOs and VMs and these are two disks I want to add without having to format.

Do you have these disks from a previous Proxmox VE install or are they just from some random source?

If you don't care about the data and just don't want to format them, check out this post by my colleague https://forum.proxmox.com/threads/unable-to-add-directory.66148/post-297552
That procedure should not be too time-consuming.

He probably cares about data since there are VMs on these disks...

Yes, the disks are from a previous installation.
but what I have in mind is to install everything as i want and make the changes/settings i want, then make an image with clonezilla and if anything happens just put the image back and add the disks with the data without formatting them!
is this possible? or is this the wrong way to do proxmox backups?

Thanks
