oVirtBackup
This is a tool, written in Python, to make online fullbackup's of a VM which runs in an oVirt environment.
Requirements
It is necessary to install the oVirt Python-sdk. In addition when running Pyhon < 2.7 you need you install argparse.

Usage
Take a look at the usage text.
backup.py -h
Configuration
Take a look at the example "config_example.cfg"
Workflow
- Create a snapshot
- Clone the snapshot into a new VM
- Delete the snapshot
- Delete previous backups (if set)
- Export the VM to the NFS share
- Delete the VM
Useful tips
crontab
00 20 * * * /home/backup/oVirtBackup.git/backup.py -c /home/backup/oVirtBackup.git/config_webserver.cfg -d >> /var/log/oVirtBackup/webserver.log
Logrotate: /etc/logrotate.d/oVirtBackup
/var/log/oVirtBackup/* {

}
Security
Set permissions to config.cfg only for the needed user (chmod 600 config.cfg).
TODO's
- When the ovirtsdk supports exporting a snapshot directly to a domain, the step of a VM creation can be removed to save some disk space during backup
