[ovirt-users] Incremental backup using ovirt api

[smidhunraj]

Hi,
I tried to take incremental backup of a vm using this script.

 public function downloadDiskIncremental(){

  $data=array();



   $xmlStr = "

  incremental
 
";

  $curlParam=array(
  "url" => 
"vms/4044e014-7e20-4dbc-abe5-64690ec45f63/diskattachments",
  "method" => "POST",
  "data" =>$xmlStr,


  );
}

But it is throwing me error as
Array ( [status] => error [message] => For correct usage, see: 
https://ovirt.bobcares.com/ovirt-engine/api/v4/model#services/disk-attachments/methods/add
 
Please help me with this issue

[smidhunraj]

I'm trying to clone the snapshot into a new vm. The tool I am using is 
ovirtBAckup from the github wefixit-AT The link is here 
https://github.com/wefixit-AT/oVirtBackup

this piece of code snippet throws me error.

if not config.get_dry_run():
api.vms.add(params.VM(name=vm_clone_name, memory=vm.get_memory(), 
cluster=api.clusters.get(config.get_cluster_name()), snapshots=snapshots_param))
VMTools.wait_for_vm_operation(api, config, "Cloning", vm_from_list)
print 'hello'
logger.info("Cloning finished")

The above lines are from the 325 line number of backup.py of the github.

I am getting error as

!!! Got a RequestError: 
status: 409
reason: Conflict
detail: Cannot add VM. The VM is performing an operation on a Snapshot. Please 
wait for the operation to finish, and try again.
How can i further debug the code to know what is happening wrong in my 
program.I am new to python please help me.
