Wouldn't it be more logical to take a snapshot, get the then read-only disk and export it directly from any host that can read it, and finally remove the snapshot ? Why the need to clone AND export ? What is the limitation to pull this VM directlly from host decreasing the time it takes the overall process and mainly the amount of storage necessary to do this job.

I didnt know that, we may adapt it in the future, but at first we will probably just write a basic set of scripts for minimal backup functionally since our dev time is limited.
Ill keep you in mind when looking into it.

Hi Bernardo,
Thanks, I knew this tool, but it is based on sdk3 which will be removed in the next version 4.2, so I'm looking at sdk4 project.
You may want to adapt it?

Hello Victor,
I have some questions about your script
Le 07/07/2017 à 23:40, Victor José Acosta Domínguez a écrit :
Hello everyone, i created a python tool to backup and restore oVirt's VMs.
Also i created a little "how to" on my blog: http://blog.infratic.com/2017/07/create-ovirtrhevs-vm-backup/ <http://blog.infratic.com/2017/07/create-ovirtrhevs-vm-backup/>
* Backup step is okay, and I get a usable qcow2 image of the snapshot vm in the backup vm. It seems to be compliant with the official backup API, except on the step 2.
1. /Take a snapshot of the virtual machine to be backed up - (existing oVirt REST API operation)/ 2. /Back up the virtual machine configuration at the time of the snapshot (the disk configuration can be backed up as well if needed) - (added capability to oVirt as part of the Backup API)/
I can't see any vm configuration anywhere but only the qcow2 disk itself
1. /Attach the disk snapshots that were created in (1) to the virtual appliance for data backup - (added capability to oVirt as part of the Backup API)/ 2. / / 3. /Detach the disk snapshots that were attached in (4) from the virtual appliance - (added capability to oVirt as part of the Backup API)/
An other case is when the vm to backup has more than one disk. After I tested it, I found that only one qcow2 disk is saved on the backup vm. This is really a matter when the original vm has many disks part of lvm, it makes the vm restoration unusable.
* About vm restoration, it seems that you are using the upload_disk api, so the disk is uploaded to the pre-defined storage domain, so it is not a real vm restoration.
Do you plan to backup and restore a full VM (disks + vm definition) in a next release?
I hope it help someone else
Regards
Victor Acosta
