Automatic, non-scheduled backups...
 

I have a laptop that I'd like to fire off a backup every time it sees it's connected to a backup volume.

I see that by running cronjob -l that SD! puts cron entries into my crontab. Would it be possible to change them so that there's a "mount | 'grep /Volumes/vol name here' &&" bit run before the "open ...." command?

Oh, and obviously set the command to run every 10 minutes or so.

You could also follow the general steps in the "One Touch Button" FAQ, but use "Do Something When" (see VersionTracker) to run the script rather than the button...

I linkified your answer. Thanks - and as a new SD! customer thanks for a great piece of s/w!
