Order Xen-Orchestra to snapshot all running VMs.

This tool aims to provide automated backup solution for your VMs (with the help of XO), until we implement this feature directly in the web interface.

Thanks to the XO architecture, you can backup all your VMs, regardless of which host they are.

How it works (so far)

We choose to create a snapshot of all your running VMs, on all XO connected servers. You can execute this script manually, or call it in a Cron job.


Install Node.js, then the xo-backup package:

npm install -g xo-backup


> xo-backup --help
Usage: xo-backup [--max-snapshots <n>] --token <token> <url>
       xo-backup [--max-snapshots <n>] --user <user> [--password <password>] <url>
  URL of the XO instance to connect to (
  Token to use for authentication.
<user>, <password>
  User/password to use for authentication.
  If not provided, the password will be asked.
  If defined, all (automatic) snapshots but the last <n> will be deleted.

With Cron

Here is an example for making a snapshot every night at 2am with 7 days of history:

30 2 * * * xo-backup --max-snapshots 7 --user --password admin


Thanks to npm, it's trivial to update this tool:

sudo npm update --global xo-backup
