MPU Data Backups

The MPU has a number of servers containing master data. Most are backed up off-site using rsync+rmirror.

Rmirror backups are run by the Services Unit. They have a page which describes how to set up a client for mirroring. The nightly results of the mirrors can be checked from each client machine using om rmirrorclient report or all together on the Mirrors Report page.

Because mirrors can be moved around from time to time it no longer makes sense to list the exact mirror locations here. To find a mirror's location, first look on the results page to find the name of the mirror server used for that particular mirror; then login to that server and look in its /disk/rmirror partitions and/or its qxprof rmirror resources.

All mirrors have been checked (most recently: November 2012) to make sure that mirroring is succeeding, that it is at a separate site from the master copy, and that the mirror partition is being taped (except where noted below).

The current host of a VM can be found with kvmtool --name myhost locate.


pinemarten is the pkgforge master server and is a virtual machine in the Forum. It has 1 rmirror entry - pkgforgedb.


budapest is the web server and is a real machine in the Forum. It has 2 rmirror entries - lcfgdatadisk mirrored from and lcfgwiki mirrored from


heda is the server and is a VM in the Forum. It has one rmirror entry bugdata.


sernabatim is the diydice LCFG server and is a virtual machine based at KB. It has 1 rmirror entry diydice which is mirrored from


schiff is the LCFG master and is a real machine in the Forum. It has 2 rmirror entries - lcfgrfedata which is mirrored from and lcfgsvn which is mirrored from Note that for this machine we also have backups on the LCFG disaster recovery machine (lcfg-dr) which are likely to be much more up-to-date.

KVM hosts

Each KVM host has an rmirror entry called kvmconf to mirror its KVM guests' configuration files.

The SimpleKVMDocs page summarises the current KVM hosts and their whereabouts.


telford is the packages mirror server and is a real machine in the Forum. It is an AFS server; our master copies of the mirrors are held in AFS volumes which it hosts. These are all backed up with TiBS.
