Previous Description (2011-12-19 11:48:11):

The backup server that allows users to recover files on Unix machines such as www.queensu.ca,post.queensu.ca and jeff-lab.queensu.ca is currently unavailable. Users will not be able to use the recover command to restore files until the service is restored.

IT Services is working on the issue and will update when the service is restored.
