PVE VMA extract

Image with all the necessary dependencies to extract/verify a "backup" file from Proxmox VE.

The image exposes /backup as a good place to mount the folder with the backup.

Uncrompress the archive with:

$ unzstd ./file.vma.zst

Or directly print it

$ zstdcat ./file.vma.zst

Then extract the archive with

$ vma extract ./file.vma -v ./vmaextract

Or verify it

$ zstdcat ./file.vma.zst | vma verify -v -
