Backups for Macintosh using the Legato System or Snapshots or Apple TimeMachine

For Faculty and Staff - To verify that your Mac is being backed up by Legato Networker

In a Terminal window, enter:

mminfo -s backup.cs -c hhhhhh -t "5 days ago"

Where hhhhhh is the hostname of your machine - as Networker knows it. It may be the first part of the response to the hostname command, or it may be the "Sharing" name under System Preferences.

For Staff and Faculty - File Recovery

This link can be used for recovering files in CS however the backup machine name is "backup.cs" instead of "hoover"

For Students and Tutors using the Mac Labs and Workstations as of September 2006

The student home directories are now stored on the Netapp, so snapshot backups ARE available:

  • open Finder
  • click on your home directory (eg iturner)
  • on the Finder top line click "go" then select "go to folder" from the drop-down
  • type ".snapshot" in the text field and click "Go"

The .snapshot directory, and all the backups will appear in the window;

  • navigate to the most recent backup with the file or directory you want to recover
  • click on the file, then "edit", click "copy filename", then
  • click the directory you want to recover "to", and "edit", "paste"

(I tried "click and drag" but it squawked about needing admin permissions to change Finder settings)

Adding Legato daemon to a client Mac

CSCF must know that the machine is to be backed up. Talk to your point of contact about this.

Basic installation and setup instructions from IST are applicable, but the server setup is not optional and you should replace all occurrences of "hoover" with "backup.cs".

You can obtain the client here.

There is documentation describing how to open up your client firewall, if need be.
