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.

https://github.com/wefixit-AT/oVirtBackup

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)

Ovirt 4.0.3 

The script output: 

Jan 05 14:12:16: Start backup for: wiki (20 GB)

Jan 05 14:12:17: Snapshot creation started ...

Jan 05 14:12:30: Snapshot created

Jan 05 14:12:40: Clone into VM started ...

Jan 05 14:36:37: Cloning finished

Jan 05 14:36:38: Snapshot deletion started ...

Jan 05 15:07:09: Delete cloned VM started ...

Jan 05 15:07:15: Cloned VM deleted

Jan 05 15:07:15: Duration: 55:0 minutes

Jan 05 15:07:15: VM exported as wiki_BACKUP_010516

Jan 05 15:07:15: Backup done for: wiki

Jan 05 15:07:15: All backups done

Thanks,

Florain
