Hallo everyone, 

I would like to update my Ovirt installation but, before that I would like to create proper VM backups. Currently I try to automate the backups and I use the implementation of the following project.

The main idea is to use the Ovirt-API to trigger a snapshot, create a new VM from the snapshot, delete the snapshot, export the vm to the export domain, delete the vm.

This process takes even with only a 20 GB vm disk 55 Minutes. I have now 21 VMs with average 30 GB HDD space, that would mean that the backup job runs 22 hours. 

Is there something wrong with my setup? 
Config? 
Is there a better way to automate backups? 
Is anyone else doing VM Exports as backup or are you just using snapshots? 


Specs: 
HA Cluster 3 Nodes each has:
2x 6x 2.96 GHz, 96 GB RAM, 120 GB HDD for CentOS7, 1 TB SSD VM-Storage (Gluster FS), 4x 1 GBit LAN Bond, 4x 1GBit SAN Bond (Gluster Network, connection to Backup NAS/ Export Domain)

If you are using Gluster I'd utilize geo-replication.
See https://github.com/sabose/ovirt-georep-backup

Ovirt 4.0.3 

I'd upgrade. 
Y. 


The script output:

Thanks,
Florain
