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 -
