vma.py implements an extraction tool for the VMA backup format used by
Proxmox. The tool is implemented in Python3.
Usage:
./vma.py path/to/source.vma path/to/target/directoryI think it is pretty important to be able to read Proxmox backups outside of a Proxmox environment. Yet, porting their VMA implementation to a standalone tool proved difficult. VMA-Reader and VMA-Writer are implemented as patches to the Proxmox-patched version and Qemu and are thus very difficult to compile on non-Proxmox systems.
The format specification can be found on git.proxmox.com.
