Sometimes you have to suffer through the hard way once or twice just to find out... there's an easier way. I've posted recently about commercial backup applications that trigger a backup when you connect a target drive; I've posted on roll-your-own scripts that do the same thing. Over at MacOSXHints, an enterprising soul took the scripts from post #2 and enhanced/extended them. Great effort, everyone!
Then, along comes a comment to the scripting hint: "Hey, why not just use Do Something When?" Gosh, never heard of that, let's check it out... gadzooks! A preference pane that launches an application or document when a drive is mounted! Why, with that plus SuperDuper!, or Automator, or even rsync/rsnapshot and Platypus -- you'd be a backup machine.
So, the way to trigger backups on mount can be summed up thusly:
- Create your backup script in your tool of choice and save as a document or applet.
- Trigger that script when your drive is mounted, using DSW.
- There is no step three. There's no step 3!
