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 to ensure 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.
