QEMU/KVM EXTERNAL SNAPSHOTS (offline)

This script will help you make backups of your virtual machines in offline mode using the virsh tool.

NOTES:

• Make sure the disks of virtual machines they're added at least one pool. Because the script searches for disks on pools.
• The script needs privilege to run virsh
• To automate the script you can use crontab tool
