During my honey moon trip in NZ, our camping car was totally wiped out by thieves, including all of the memory cards which contained 2 month worth of our traveling photos.  No amount of money can replace that.  Extremely frustrating.

 

Nowadays, I use the following setup to minimize the risk of losing any data:

• My PC has 3 TB mirrored (2 x 3TB configured in RAID 1).
  
• I have an external storage SAN using the same config (2 x 3TB in RAID 1; thinking of upgrading to 4 x 3TB in RAID 6 for even better reliability).
  
• I have CrashPlan as online backup service (unlimited space for < $100/year).
  

All this means is that I have 5 copies of my entire hard disk.  I also have a subset of important files on Dropbox (100 GB) to minimize the loss on sensitive data even more  (with a 30 day history capability - great when deleting or updating files by accident).

 

I run external storage backups on a regular basis (every other day or when a lot of stuff changes at once).

The limited upload bandwidth for the online service is not much of a problem as my PC is always on 24/7.

 

With this setup, my risk of actually losing data is close to zero.
