FYI about Back Blaze:
"I use the service backblaze.com to back up my Mac. Well, I thought I did. Fortunately a friend hammered into me "if you haven't restored a file, you don't have backups", so I tried to restore one, and lo and behold it wasn't backed up.
It turns out that backblaze scans your machine slowly, looking for files that have been modified. It then schedules them to be sent off to their server. This has several problems.
1) If your machine is set to go to sleep after a while of inactivity, the scans stop. Backblaze doesn't alert you to this.
2) If you click their "backup now" button, all it does is transmit files it has already found to their server, and say "everything's backed up!". It doesn't start a new scan.
3) As best I can tell, there is no way to determine when it starts or completes a scan.
4) As best I can tell, there is no way to initiate a scan.
5) If you use a removable drive, there's no hint that it didn't have enough time to scan it and back it up before you disconnected it. In my case, I left it connected for four days, and it still wasn't backed up. This was with their throttle control set to full speed.
6) Upon complaining about this, I get hand-waving from them. Nobody there seems concerned.
All in all, I am underwhelmed."

It's funny you posted this, I'm headed to Fry's this weekend for an external HD for photos and scrap stuffs. My power supply on my desktop bit the dust. It then dawned on me that that pc isn't backed up with an external drive and what would I do if my HD died on that machine?! Oops! I will prob sign up for Crash Plan after getting all that done. In theory, I want to use the online backup as a secondary precaution.
I did finally go between the phones and the two laptops and gather all the random photos and put them one one machine. Now to get the big pc working and everything moved to it. First world problems lol.
