Three weeks ago the hard drive in my MacBook Pro went bad. So far as I can tell, I didn’t lose a single byte of data. Here’s how.
DiskWarrior and SuperDuper are indeed fantastic. Dropbox is in many ways very well done. Why can’t iDisk work like that? Still, I wish there were an option to operate Dropbox in non-haxie mode, where it didn’t load its code into the Finder. And I think that the company has been irresponsible with their users’ resource forks and metadata (and also with disclosing which parts of the files they sync). However, there is now a beta version that addresses these issues, so hopefully they’ll soon be a thing of the past.
Gruber potentially had a problem because his SuperDuper clone was over 10 days old, since he had been out of town. His solution: back up important files constantly to Dropbox. My solution: travel with a portable clone drive and back up important files to CrashPlan.
