Managed Customer (VM) backup

This document concerns end-users/customers. See [[datacenterlight:Backup]] page for server-side documentation.


This document is a DRAFT.


We make use of the ccollect software, which runs every day at 3AM Europe/Zurich. The backup server and storage clusters are in a location (place5) physically separated from the customer VMs (place6).


How to enable this service?

You will have to contact our support and give them the following details:

  • Address of the VM to backup (IPv6 or domain with AAAA field).
  • Directories to backup. Default is / excluding /sys and /proc.

ccollect makes use of rsync to transfer data and needs to connect to your server over SSH (rsync itself is not encrypted!). You need to configure an user - root for a full system backup - with the following SSH key (to put in ~/.ssh/authorized_keys):

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7LsZp048K5D2kSWwiI5fux5pv4Ji7eTtMZGpOu0MviZEuGG3T5NeSKPmdlG1Rr3/oLpIqaFPzB7la3SI0OX5/E3v/yWcSrIsXdoIlSJMx7yaWrd4rm3yICukg4v5cZm2iDGBzIffpRxN1aPg46XnwmSvID3dD18yHMfgKyOFJgMwpTeI0d+K99cRYdf0D+QoUUyJlEes8xOw29lfT+1gg3KXBfYeggXLxMQ1xOH5L91j3Lg1taaD0EfyvkjO+TspcEwIwEtcBwdGRDbkjNkZOgFUEoWpxEFESLFRvr+JxgDJjvkLD4Q7l6tNOvW30oq7iI961NbXSwgM1cH0gNPED ungleich-backup
