Vzdump is a utility to make consistent snapshots of OpenVZ containers (and KVM virtual machines in case you are using Proxmox VE).

It fundamentally creates a tar archive of the container’s private area which also includes the CT configuration files.

The following steps are for Debian Squeeze Linux but vzdump can be used on all other linux distributions

1. Install Vzdump on Deian Squeeze:

apt-get install vzdump

You can also download and install vzdump from the follwing link:


and install it:

dpkg -i vzdump_1.2-4_all.deb

2. How to use Vzdump:

a. Create backups:

You can create a backup of ALL virtual machines as tar.gz  archive and send a email report when finished.
