Always backup your data - three different ways!

The last few weeks I’ve had disk corruption issues on my two year old Macbook Pro’s original internal hard drive. The machine and drive still worked, but I needed to bring the machine into the Genius Bar to get a hard disk replacement.

In preparation I dutifully backed up my machine via Time Machine to an attached Firewire drive at least every day. I dutifully backed up my source code to a remote server with git. I added a third layer of backup to my local NAS device using Chronosync.

I am a bit surprised by a couple of things, though suprised is perhaps too strong a word.

There is an interesting post by Om Malik over at GigaOm suggesting how Google can get it mojo back from Facebook.

Taking a slight spin on this, I make the observation that a large part of Facebook's value is your identity and your associations and Facebook's willingness to leverage this information elsewhere on the web (Facebook Connect). Facebook Connect is becoming the most common way to login to other sites. The reputation of your identity is increased by your associations: it requires a consipricy to create a fake Facebook account and have N friends, the presence of which increases your identity's reputation.
