Over the weekend I wrote virt-back, a backup utility for QEMU, KVM, XEN, or Virtualbox guests.
virt-back is a python application that uses the libvirt API to safely shutdown, gzip, and restart guests.
The backup process logs to syslog for auditing and virt-back works great with cron for scheduling outages. Virt-back is in active development so feel free to give suggestions or branch the source.
virt-back has been placed in the public domain and the latest version may be downloaded here:
The fastest way to install virt-back is to use pip or setuptools.
Try sudo pip install virt-back or sudo easy_install virt-back
Otherwise you may manually install virt-back
sudo wget https://bitbucket.org/russellballestrini/virt-back/raw/tip/virt-back \ -O /usr/local/bin/virt-back
sudo chmod 755 /usr/local/bin/virt-back
