We just created vzdup.

vzdup is a utility to make consistent snapshots of OpenVZ containers. It basically creates an encrypted duplicity archive of the container's private area and configuration files and transfers the archive to an ssh destination. Backups can be restored with vzduprestore.

We created vzdup for our own use, but wanted to share the GPL code with the community. It probably contains a lot of bugs, but we welcome everybody to try it and also to improve it Smile vzdup has been tested only on CentOS.

The code is basically a quick hack of vzdump 1.2-13.

Here is the download link for vzdup:

Very convenient, since it does the following in one step:

- Incremental backup (huge space saver)
- Encrypt backup
- transfer to a another server via different protocols
- uses duplicity which supports S3

If you choose to stop the server for a very clean backup, vzdup allows you to start the container immediately after the snapshot, but before the long archive and compression part.

So the downtime is very short compared to vzdump for a clean backup (vzdump only restarts the container after the tar/archive process is finished).


Here is the (clickable) link:

I'm the owner of said github account - it's probably not the best idea to use that code, it's customized. But some patches may be useful to general public.

Also, thanks to Yoonique for creating it - great work, guys!
