Re: [ovirt-users] Backups take sooo long, how can I improve the situation, where is the bottleneck?

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) 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: Jan 05 14:12:16: Start backup for: wiki (20 GB) Jan 05 14:12:17: Snapshot creation started ...
