OS X Leopard: What happens when your backup disk is full?

Time Machine: Backup disk fullI always wondered what would happen if my backup disk I used for Leopard’s Time Machine feature ran out of space.

Yesterday I finally found out (and yes, I realized that it has been mentioned in the manual, also)…

As I have set up my backup partition on an external Firewire drive to exactly the same size as my hard disk inside the MacBook Pro (160 GB), that means that I’ve been producing about 60 GB of changing data since I installed Leopard and ran Time Machine for the first time in the end of November. Wow.

  1. Another hint: if you want to keep older backups, just replace the external backup drive with a new one. Store the old one in a safe place (in case you need it some day), attach the new drive and activate it as new backup drive in Time Machine.

    And if you’re not having any kind of backup solution for your Mac so far, really consider setting one up! I’ve written an article on how to perform OS X backups to an external drive a while ago.
