RHEVM/oVirt Opensource full VM Backup tool

[Victor_Acosta]

Hi all, I've been using oVIrt since version 3.5, i really love it
But i didn't find a VM backup solutions that fullfill my requirenments, so i created a little script to do it.

You can find the documentation of my script in my personal blog:
http://blog.infratic.com/create-ovirtrhevs-vm-backup/
Github repo: https://github.com/vacosta94/VirtBKP

This script litterally save my life a few times, so now i'm thinking to create a more complete backup tool based on this script, and i have this objectives:
- The new tool should be able to create a full VM backup including hardware configuration, at this moment my script only creates a DISK backup
- The new tool should be able to handle archiving and RPO policies
- The new tool should be able to create backup based on VM tags
- Should be installed and/or distributed as a simple virtual appliance

So, i want to know the community thoughts about this:
- Any ideas or suggestions?
- Am i trying to create something that already exists?
- Any good opensource and free to use VM backup solution that support oVirt/RHEVM you can recommend?

I just downloaded and tried this script, based on the instructions on your blog.  I seems easy to use, but it fails part way through the backup.

Not being a python programmer or having the time today to learn python, it looks to me like the method attach_disk expects 4 parameters, but is only being given 3.  Any thoughts?

It looks like the URL did not return the expected object - at least based on the output.
