Hi all,
vzdump is an utility to make consistent snapshots of running OpenVZ VEs. It
basically creates a tar archive of the VE private area, which also includes
the VE configuration files.
There are several ways to provide consistency:
stop the VE during backup (very long downtime)
use rsync and suspend/resume (minimal downtime).
use LVM2 (no downtime)
vzdump is available at
http://www.proxmox.com/cms_proxmox/en/technology/oss-softwar e/openvz/
License: GPL
Please read the manual page for more information (man vzdump). Suggestions
and comments are welcome.
Best regards,
Dietmar

Looks really great, thanks! Can I put it to
download.openvz.org/contrib/? I am also interested in putting your template.
From the quick review (no testing yet) I see the following really nice
things:
* LVM2 support
* a man page
* the fact that you honour both /etc/vz/vz.conf and /etc/vz/conf/$VEID.conf
* rpm/deb packages
Problems:
* in fact the only problem I see is that the source tarball does not
contain the top-level directory (usually $NAME-$VERSION/), so if you
untar it all the files are extracted to the current directory which is
not good.
* perhaps having a .spec file for rpm will be better than using alien to
build rpm. I can mock up one if needed.

That would be great - feel free to upload the files. We can also contribute installation howtos on the wiki if you want.

I will fix that tomorrow.

Unfortunately I live in a debian world and do not know much about rpm. It would be great if you create a .spec file for me (and some hints howto create the rpm).
